Description

  The present invention includes a device, a communication system, and a program.

  With the spread of networks such as the Internet and wireless communication networks, the form used by users with image forming apparatuses connected to the network has increased. If the image forming apparatus is connected to a network, a server communicating with the image forming apparatus can provide various services to the user.

  For example, a technique has been devised for confirming a use state by utilizing that an image forming apparatus is connected to a server (see, for example, Patent Document 1). Japanese Patent Application Laid-Open No. 2004-151820 discloses a system in which the function of the image forming apparatus is stopped when the image forming apparatus transmits the usage frequency to the server and charging based on the usage frequency cannot be performed with the balance of the advance payment.

  As an example of the above service, the server can provide a maintenance service to an image forming apparatus connected via a network. Since an image forming apparatus such as a printer is a precision device, not only simple maintenance such as toner replacement but also regular maintenance by an expert is preferable. For this reason, the customer does not purchase the image forming apparatus from the sales company, but the customer may rent or lease the image forming apparatus with the sales company and enter into a maintenance contract. As a result, the user can receive a regular maintenance service by a customer engineer who is a maintenance specialist, or can receive a maintenance service whenever a problem occurs.

    In maintenance via the network, the image forming apparatus periodically transmits its own diagnosis information (cumulative print number, remaining toner amount, error information, etc.) to the server. The server compares the diagnostic information with the failure information of various past models, detects a failure sign, and determines necessary maintenance. As a result, if necessary, a customer engineer will be dispatched to perform appropriate maintenance, and inspections will be performed to prevent failure.

JP 2008-305186 A

However, if the image forming apparatus cannot communicate with the server, diagnostic information cannot be transmitted to the server, which makes it difficult to maintain over the network. For example, depending on the customer, the image forming apparatus may be used in an area where the communication status is poor, or the user may be disconnected from the network without being aware of it. If the state where communication with the server cannot be continued continues, the server cannot grasp the state of the image forming apparatus and cannot provide preferable maintenance.
In view of the above problems, an embodiment of the present invention aims to provide a device that performs an appropriate response when communication with the outside is not possible.

An embodiment of the present invention is a device that transmits a usage status to an information processing apparatus that can communicate via a network, and a function providing unit that provides a predetermined function; A communication means for transmitting; a determination means for determining whether the communication means has transmitted the usage status to the information processing apparatus; and a determination means for determining that the communication means cannot transmit the usage status to the information processing apparatus.

The registration number is the same as in Table 3. In the availability, it is registered whether or not the usage status Ud is periodically received from the image forming apparatus 20. Note that the term “periodic” does not need to be a fixed period, and means that the data can be received with a frequency that can be charged (for example, if the monthly fee is charged, the fee can be charged even once or more a month). For example, if the usage status Ud can be received, the usage permission is set, and if not, the usage limit is set. The reception time is the date and time when the usage status Ud was last received from the image forming apparatus 20. The counter information is the cumulative print frequency (number of pages) received last from the image forming apparatus 20. In addition, in addition to use permission and use restrictions, you may register unusable in usability.

  Next, the functional configuration of the management device 40 will be described. The transmission / reception unit 41 is realized by a command from the CPU 201 illustrated in FIG. 3 and the communication unit 207 illustrated in FIG. 3. The transmission / reception unit 41 is connected to the sales server 60, the image forming apparatus 20, and various data via the network N. Send and receive.

  The device management unit 43 is realized by an instruction from the CPU 201 shown in FIG. 3, and registers and updates a record in the device management table. Specifically, the contract information is received from the sales server, or the record is registered in the device management table in accordance with the operation of the operator of the management apparatus. At this time, a registration number is assigned. Further, when a registration status confirmation request is received from the image forming apparatus 20, “already set in the image forming apparatus” is set.

  The usage frequency management unit 42 is realized by an instruction from the CPU 201 shown in FIG. 3 and updates the record of the usage frequency management table based on the usage status Ud received from the image forming apparatus 20.

  The operation accepting unit 44 is realized by an instruction from the CPU 201 and the input unit 205 shown in FIG. 3 and accepts inputs of various operations of an operator who operates the management apparatus 40. For example, when contract information is received from the sales server 60, the operator creates a record in the device management table based on the contract information (when the operator registers).

≪Image forming device≫
The image forming apparatus 20 includes a transmission / reception unit 21, a registration status confirmation unit 22, a usage frequency recording unit 23, a communication availability determination unit 24, a usage status transmission unit 25, a usage restriction unit 26, and a storage / reading unit 29. Yes. Each of these units included in the image forming apparatus 20 operates according to a command from the CPU 301 according to the usage management program 2100 expanded from the flash memory 303 onto the SDRAM 302. It is a function realized by this, or a means to be functioned.

  In addition, the image forming apparatus 20 includes a storage unit 2000 constructed by the flash memory 303 and the HDD 304 shown in FIG. In the storage unit 2000, a usage management program 2100, a registration status confirmation response 2002, a usage permission 2003 or usage limit 2004, and a usage frequency information DB 2001 are constructed. The registration status confirmation response 2002 is stored when the image forming apparatus 20 receives the registration status confirmation response 2002 from the management device 40. The use permission 2003 is stored when the image forming apparatus 20 receives a use status response from the management apparatus 40. The use restriction 2004 is stored when the communication availability determination unit 24 determines that communication with the management apparatus 40 is not possible.

記憶部２０００には、表５に示されているような使用度数情報テーブルによって構成されている使用度数情報ＤＢ２００１が構築されている。使用度数情報テーブルには、送信日時に対応づけて、用紙サイズと印刷色のいくつかの組ごとに累積の印刷枚数（カウンター情報）が記録されている。送信日時はカウンター情報を画像形成装置２０が管理装置４０に送信した（実際に管理装置４０まで送信できた）日時である。なお、上記のように使用状況Ｕｄは表５の内容には限られない。

In the storage unit 2000, a usage frequency information DB 2001 configured by a usage frequency information table as shown in Table 5 is constructed. In the usage frequency information table, the cumulative number of printed sheets (counter information) is recorded for each set of paper size and printing color in association with the transmission date and time. The transmission date / time is the date / time when the image forming apparatus 20 transmitted the counter information to the management apparatus 40 (actually, the counter information could be transmitted to the management apparatus 40). As described above, the usage situation Ud is not limited to the contents of Table 5.

  Next, the functional configuration of the image forming apparatus 20 will be described. The transmission / reception unit 21 is realized by a command from the CPU 301 illustrated in FIG. 4 and the NIC 306 illustrated in FIG. 4, and transmits / receives various data to / from the management device 40 and the information terminal 10 via the network N. .

  The registration status confirmation unit 22 is realized by a command from the CPU 301 and the operation unit 307 shown in FIG. 4, and transmits a registration status confirmation request to the management apparatus 40. When a registration status confirmation response indicating that the registration is received from the management apparatus 40 in response to the transmission of the registration status confirmation request, the confirmation result is displayed on the operation unit 307. Also, a registration status confirmation response 2002 is stored in the storage unit 2000.

  The usage frequency recording unit 23 is realized by the command from the CPU 301 and the plotter engine 311 shown in FIG. 4. The usage frequency recording unit 23 counts the number of pages printed and displays the accumulated counter information up to the present as a set of paper size and print color. Record each in the usage frequency information table.

  The usage status transmission unit 25 is realized by a command from the CPU 301 shown in FIG. 4, and transmits the usage status Ud to the management device 40 via the transmission / reception unit 21 periodically or at a fixed timing. The usage status Ud is transmitted when the registration status confirmation response 2002 is stored in the storage unit 2000. As the usage status Ud, the counter information stored in the usage frequency information DB 2001 is transmitted together with, for example, a registration number for identifying the own device.

  The communication availability determination unit 24 is realized by an instruction from the CPU 301 illustrated in FIG. 4, and determines whether the usage status transmission unit 25 has transmitted the usage status Ud to the management device 40.

  The use restriction unit 26 is realized by a command from the CPU 301 illustrated in FIG. 4, the operation unit 307, the NIC 306, and the like. When the use restriction 2004 is stored in the storage unit 2000, the function of the image forming apparatus 20 is used. At least a part of the image forming apparatus is locked so that the user cannot use the image forming apparatus. Note that even when there is an unusable response from the management device 40 (for example, due to insufficient balance), at least a part of the functions of the image forming device 20 is locked. When the image forming apparatus 20 has functions of printing, FAX transmission, FAX reception, copying, and scanning, one or more users among these cannot be used. As a method of restricting use, for example, the operation unit 307 may not accept an operation. In this case, the operation unit 307 does not accept hard key input. Further, even if the operation unit 307 does not display the menu on the touch panel or displays the menu, no input is accepted (when the copy function is limited, the copy menu is not displayed or the selection is not accepted). Thereby, the use of the image forming apparatus 20 from the operation unit 307 can be restricted. Note that operations other than using the functions of the image forming apparatus 20 such as printing, FAX transmission, FAX reception, copying, and scanning may be accepted. Thereby, when the use is restricted, it is possible to display the use restriction on the operation unit 307, the reason, and the solution method.

  Further, as a method of restricting use, there is a method in which the image forming apparatus 20 does not print print data that is created by a PC or the like with a printer driver and transmitted via the network N. The usage restriction unit 26 discards the print data received by the NIC 306 or rejects the reception before the NIC 306 receives the print data. Alternatively, it may be handled as a print job that has received print data but ended without printing.

<Operation procedure>
Next, an operation procedure of the print management system 100 will be described.

≪Registration of customer information≫
FIG. 6 is an example of a sequence diagram illustrating an operation procedure of the print management system 100 when the image forming apparatus 20 is purchased.

  S1: For example, the information terminal 10 accesses the Web page of the sales server 60 by the user's operation, and the operation reception unit 12 receives the user's operation. Thereby, the input of payment information and customer information is received. The transmission / reception unit 11 of the information terminal 10 transmits settlement information and customer information to the sales server 60 together with an application for purchase or rental of a product.

  S2: The transmission / reception unit 61 of the sales server 60 receives the purchase application, and the application reception unit 62 registers the customer information in the record of the customer management DB 6001 and the contract information in the record of the contract information DB 6002. That is, a customer ID that is not duplicated is assigned to the customer management DB 6001 if necessary, and the customer name, address, contact information, and representative are registered. Further, a sales code that does not overlap is assigned to the contract information DB 6002, and a customer ID, a device number purchased by the user, a sales date, and a contract period (in the case of rental) are registered. It should be noted that the settlement state is not yet established and the contract information is not transmitted or not.

  S3: The settlement request unit 63 of the sales server 60 requests the settlement organization 80 for settlement.

  S4: The settlement organization 80 performs settlement, and transmits settlement completion to the sales server 60.

  S5: Thereby, the sales server 60 transmits settlement completion to the information terminal 10. Payment completion may be sent by e-mail or via a web page.

  S6: The application receiving unit 62 of the sales server 60 registers “completed” in the settlement state of the contract information DB 6002.

  S7: Also, since the contract is completed, the contract information transmission unit 64 of the sales server 60 transmits the contract information to the management apparatus 40.

  S8: The application receiving unit 62 of the sales server 60 registers the transmission in the contract information transmission / non-existence of the contract information DB 6002.

<< Notification of Usage Status from Image Forming Apparatus 20 to Management Apparatus 40 >>
FIG. 7 is an example of a sequence diagram illustrating a procedure for the image forming apparatus 20 to notify the management apparatus 40 of the usage status Ud.

  S1: First, the transmission / reception unit 41 of the management apparatus 40 receives the contract information.

  S2: The device management unit 43 of the management device 40 issues a registration number. The device management unit 43 registers the registration number, device number, and customer ID in the device registration information DB 4001. “Installation state of image forming apparatus” in the device management table is not set. A terminal such as a PC operated by the operator of the management apparatus 40 may receive the contract information. In this case, the operator may input the device number and customer ID into the device registration information DB 4001. Similarly, when the management device 40 receives the contract information, the operator may register the device number and the customer ID. The device management unit 43 issues a registration number by registering the device number and customer ID.

  The registration number is notified to the image forming apparatus 20. Specifically, for example, the operator of the management apparatus 40 transmits the information to the user of the image forming apparatus 20 by e-mail, telephone, or FAX. Alternatively, the person in charge of the shipping source may set a registration number in the image forming apparatus 20 before delivery of the image forming apparatus 20. Alternatively, the delivery number may be held by the delivery person assigned by the management apparatus 40 and set in the image forming apparatus 20 at the time of installation to the customer.

  S3: When the payment is completed (or may be before the payment is completed), the image forming apparatus 20 is delivered to the customer and installed.

  S4: The image forming apparatus 20 cannot be used by the user until a registration status confirmation response is received from the management apparatus 40. For this reason, the registration status confirmation unit 22 of the image forming apparatus 20 transmits a registration status confirmation request to the management device 40 together with the registration number of the own apparatus and the usage status Ud. If the device number has an identification capability for identifying the image forming apparatus 20, the device number may be transmitted to the management device 40. Alternatively, both the device number and the registration number may be transmitted. The registration status confirmation request may be transmitted when the user operates, or may be transmitted when it is detected that the registration status confirmation response 2002 is not stored in the storage unit 2000.

  S5: When the transmission / reception unit 41 of the management device 40 receives the registration status confirmation request, the device management unit 43 refers to the device registration information DB 4001 and determines whether or not the registration number received from the image forming apparatus 20 is registered. In this embodiment, it is assumed that a registration number is registered. At this time, “installation state of image forming apparatus” in the device management table is not set. If the registration number is registered in the device registration information DB 4001, since the contract is complete, the device management unit 43 updates the “image forming apparatus installation state” in the device management table to “set”.

  S6: The transmission / reception unit 41 of the management apparatus 40 transmits a registration status confirmation response to the image forming apparatus 20.

  S7: The storage / reading unit 29 of the image forming apparatus 20 records the registration status confirmation response 2002 in the storage unit 2000. As a result, the user can use the image forming apparatus 20.

  S8: When the image forming apparatus 20 registers itself in the management apparatus 40 (when a registration status confirmation response is received), the usage status transmission unit 25 of the image forming apparatus 20 periodically updates the usage status Ud together with the registration number. Send to. This regular transmission is performed, for example, at a predetermined time of the day (after the power is turned on if the power of the image forming apparatus 20 is not turned on at this time) or at regular intervals. The transmission interval may be once every two days, once a week, once a month, or the like. Moreover, you may transmit twice a day.

  S9: When the transmission / reception unit 41 of the management device 40 receives the usage status Ud, the usage frequency management unit 42 registers the reception time and usage status (counter information) Ud in association with the registration number of the usage frequency management DB 4002.

  S10: The transmission / reception unit 41 of the management apparatus 40 transmits a usage status response to the image forming apparatus 20. The usage status response is a response notifying that usage is permitted or not. For example, when the balance of the management device 40 is insufficient, there may be a case where it is notified that the use is not possible. In this embodiment, it is assumed that the use permission is notified.

  S11: The transmission / reception unit 21 of the image forming apparatus 20 receives a usage status response (use permission). As a result, the storage / reading unit 29 of the image forming apparatus 20 stores the use permission 2003 in the storage unit 2000.

≪Usage notification process≫
Next, the periodic transmission of the usage status Ud to the management device 40 will be described in detail. FIG. 8 shows an example of a flowchart showing a procedure for transmitting the usage status Ud in step S8 of FIG. The process of FIG. 8 is repeatedly executed periodically.

  First, the usage status transmission unit 25 determines whether a time interval for performing usage status notification has passed. For example, when transmitting once a day, it is determined whether or not 24 hours have elapsed since the last transmission time (S10).

  When the determination in step S10 is Yes, the usage status transmission unit 25 transmits the usage status Ud (S20).

  The communication availability determination unit 24 determines whether or not the usage status Ud has been transmitted to the management device 40 (S30). For example, in response to transmission of the usage status Ud, when a usage status response indicating permission for use is received from the management device 40, it is determined that the usage status Ud has been transmitted to the management device 40. Although it is determined that transmission is possible even when an unusable usage status response is received, this is similar to the usage restriction in that the user cannot use the image forming apparatus 20 due to the unusable state. Accordingly, it is determined No in step S30, except that the image forming apparatus 20 receives a use status response indicating that use is permitted or unusable. Note that the situations determined as No include the case where the image forming apparatus 20 is not connected to the network N, and the case where the image forming apparatus 20 is connected to the network N but the communication status is congested. There is. That the image forming apparatus 20 is not connected to the network N can be detected by the OS of the image forming apparatus 20. The congestion of the communication status can be detected by, for example, a ping command or a traceroute command.

  If the determination in step S30 is Yes, the process proceeds to step S60, and the storage / reading unit 29 of the image forming apparatus 20 stores use permission 2003 (or unusable) in the storage unit 2000 (S60). At this time, the number of retries described below is cleared.

  When the determination in step S30 is No, the process proceeds to step S40, and the communication availability determination unit 24 determines whether or not the number of transmissions of the usage status Ud exceeds the number of retries (S40). The number of retries is an upper limit number of times for retransmitting the usage status Ud, and is determined in advance.

  If the determination in step S40 is No, the usage status transmitter 25 increases the number of retries by one and tries to retransmit the usage status notification (S30). Note that the retransmission timing may be periodically performed, for example, every few minutes.

  If the determination in step S40 is Yes, it can be confirmed that the usage status Ud cannot be transmitted to the management apparatus 40, so the communication availability determination unit 24 determines to limit the use of the image forming apparatus 20 (S50). Therefore, the storage / reading unit 29 stores the use restriction 2004 in the storage unit 2000. If the use permission 2003 is already stored, the use permission 2003 is overwritten. As a result, the use restriction unit 26 restricts the use of the image forming apparatus 20, so that the user cannot use it.

  When the use is restricted, the use restriction unit 26 may display on the operation unit 307 that the use is restricted. FIG. 9 is a diagram illustrating an example of a message displayed on the operation unit 307. For example, a message such as “Currently use is restricted. To cancel, let the image forming apparatus 20 send the usage status” is displayed. Further, the message may be changed according to the reason why the usage status Ud cannot be transmitted. When not connected to the network N, a message such as “Please connect the image forming apparatus to the network” is displayed. When connected to the network N but the communication status is congested, a message such as “Check network communication status” is displayed. These messages are examples of functions being limited, and the operation unit 307 is an example of a display device.

  Accordingly, the user can grasp the reason for the use restriction and take measures such as connecting the image forming apparatus 20 to the network N.

  Note that time may be used instead of the number of retries as an index for the communication availability determination unit 24 to cancel retransmission of the usage status Ud. For example, if it is set as 30 minutes in advance, the usage status transmission unit 25 attempts to transmit the usage status Ud periodically or irregularly for 30 minutes. In this case, since it can be confirmed that transmission is not possible for a certain period of time, the communication availability determination unit 24 can reliably determine that transmission has failed.

  On the other hand, the communication availability determination unit 24 may limit the use without retrying. When it is not connected to the network N, it is not necessary to retry. Further, when the communication status is congested, it does not always recover during the retry, and as described below, the communication status recovers and the usage status Ud can be transmitted at the next transmission timing.

  Even when the usage restriction 2004 is stored in the storage unit 2000, the usage status transmission unit 25 tries to transmit the usage status Ud again at the next transmission timing. Thus, if the usage status Ud can be transmitted to the management apparatus 40, the image forming apparatus 20 can be used. Further, when the usage restriction 2004 is stored in the storage unit 2000, the usage status transmission unit 25 may attempt to transmit the usage status Ud without waiting for the next transmission timing. Thereby, when the usage status Ud can be transmitted, the downtime can be shortened. Further, the usage status Ud can be transmitted by a user operation. Thereby, when the usage status Ud can be transmitted, the use can be resumed at a timing when the user wants to use it.

  Further, when the usage status transmission unit 25 can transmit the usage status Ud to the management device 40 after the usage status Ud cannot be transmitted, the management device 40 can charge the customer based on the received usage status Ud.

  As described above, the print management system 100 according to the present embodiment can restrict a user from using the image forming apparatus 20 when the image forming apparatus 20 cannot communicate with the management apparatus 40.

  In this embodiment, an image forming apparatus 20 that can give a grace period when the usage status Ud cannot be transmitted will be described. In the present embodiment, the description will be made assuming that the configuration of the print management system 100 is the same as or different from that of the first embodiment, and there is no problem in the description.

  FIG. 10 shows an example of a flowchart showing the processing procedure of the transmission processing in step S8 of FIG. In the description of FIG. 10, steps different from those in FIG. 8 will be mainly described. The processing in steps S10 to S40 is the same as that in FIG.

  When the determination in step S40 is Yes, the communication availability determination unit 24 determines whether or not the first usage status Ud is transmitted after the number of transmissions exceeds the number of retries (S42). In addition to transmitting the usage status Ud to the management apparatus 40, it may be detected that the image forming apparatus 20 transmits some information to the management apparatus 40.

  When the determination in step S42 is Yes, the communication availability determination unit 24 sets a timer (S44). That is, when the number of retries exceeds the number of transmissions, a timer for a certain time is started from that time.

  As shown in FIG. 11, the use restriction unit 26 may display the remaining time of the fixed time on the operation unit 307 from this time point. FIG. 11 is a diagram illustrating an example of a message displayed on the operation unit 307. For example, a message such as “The image forming apparatus cannot transmit the usage status. For this reason, use of the image forming apparatus is restricted after another 60 minutes have elapsed” is displayed. The displayed time decreases with the timer count. As a result, the user can grasp how long the image forming apparatus 20 can be used.

  Returning to FIG. 10, the communication availability determination unit 24 determines whether the timer has timed out (S46).

  If the determination in step S46 is No, the process returns to step S20. Therefore, the user can use the image forming apparatus 20 until the timer counts a certain time (until time out). Further, it is possible to attempt to transmit the usage status Ud to the management apparatus 40 until the time-out occurs.

  When the time-out has occurred (Yes in S46), the communication availability determination unit 24 determines that the use of the image forming apparatus 20 is restricted (S50). Therefore, the storage / reading unit 29 stores the use restriction 2004 in the storage unit 2000.

  Therefore, according to the present embodiment, even when the usage status Ud cannot be transmitted, the user can use the image forming apparatus 20 for a certain period of time. If the image forming apparatus 20 cannot communicate with the management apparatus 40 and the image forming apparatus 20 cannot be used immediately, there is a risk that the user may have trouble with the business. On the other hand, sudden unavailability can be avoided by providing a grace period as in this embodiment.

  When the image forming apparatus 20 prints during a certain time, the latest usage status (counter information) Ud is not transmitted to the management apparatus 40. However, when the usage status transmission unit 25 can transmit the usage status Ud to the management device 40 after the usage status Ud can no longer be transmitted, the management device 40 responds to the customer based on the usage status Ud increased over a certain period of time. You can charge.

  The fixed time may be determined by the manufacturer of the image forming apparatus 20 or the operator of the management apparatus 40 as a general time (for example, 12 hours or 24 hours) until communication is restored. The predetermined time may be stored in advance in the image forming apparatus 20 or may be transmitted from the management apparatus 40.

  Further, the fixed time may not be fixed in the same image forming apparatus 20 and the same customer. For example, the image forming apparatus 20 may randomly determine when the number of transmissions exceeds the number of retries. This is because it may not be a fixed time as long as printing can be permitted for a certain period of time.

  Further, this time may vary depending on the model of the image forming apparatus 20 or may vary depending on the customer.

  In the present exemplary embodiment, an image forming apparatus 20 that can give a delay until printing of a certain number of sheets when the usage status Ud cannot be transmitted will be described. In the present embodiment, the description will be made assuming that the configuration of the print management system 100 is the same as or different from that of the first embodiment, and there is no problem in the description.

  FIG. 12 shows an example of a flowchart showing the processing procedure of the transmission processing in step S8 of FIG. In the description of FIG. 12, steps different from those in FIG. 10 are mainly described. The processing in steps S10 to S40 is the same as that in FIG.

  When the determination in step S40 is Yes, the communication availability determination unit 24 determines whether the image forming apparatus 20 has output a certain number of pages after the number of transmissions exceeds the number of retries (S43). When the number of transmissions exceeds the number of retries, the communication availability determination unit 24 counts up the number of pages printed by the image forming apparatus 20 from that time. For example, when one side is printed on one sheet, one page is the amount of output, and when two sides are printed, two pages (one printed matter) are the amount of output. It is determined that the use of the image forming apparatus 20 is permitted until the count reaches a predetermined number, and when the predetermined number is reached, the use of the image forming apparatus 20 is restricted.

  Therefore, according to the present embodiment, the user can use the image forming apparatus 20 from when the number of transmissions exceeds the number of retries until a certain page is output. If the grace period is given for a certain time, the user cannot use the image forming apparatus 20 after a certain time without using the image forming apparatus 20. On the other hand, when a grace period up to the use limit is given by a fixed number, the user can surely output until the fixed number is output.

  Also in the present embodiment, a message may be displayed on the operation unit 307 when a certain number of output margins are given. For example, a message such as “The image forming apparatus cannot transmit the usage status. Therefore, if another 300 sheets are printed, the use of the image forming apparatus is restricted.” Is displayed. The user can effectively use a certain number of sheets.

  The fixed number is determined in advance by the manufacturer of the image forming apparatus 20 and the operator of the management apparatus 40. Further, the fixed number may be stored in advance in the image forming apparatus 20 or may be transmitted from the management apparatus 40.

  Further, the fixed number may not be constant in the same image forming apparatus 20 and the same customer. For example, the image forming apparatus 20 may randomly determine when the number of transmissions exceeds the number of retries. This is because it may not be constant as long as a certain number of pages and printing can be permitted. Further, the fixed number may differ depending on the model of the image forming apparatus 20 or may differ depending on the customer.

  In addition, combining the second embodiment and the present embodiment, a longer period of time until a certain time or a certain number of sheets are output may be set as a grace period. In this way, the user can use the image forming apparatus 20 to the maximum extent after the number of transmissions exceeds the number of retries. Moreover, it is good also considering a shorter one until output of a fixed time or a fixed number of sheets is complete as a grace period. In this way, the grace period during which the user can use the image forming apparatus 20 can be limited to a minimum while giving the grace period.

  In this embodiment, the image forming apparatus 20 that can give a grace period according to the processing capability of the image forming apparatus 20 when the usage status Ud cannot be transmitted will be described.

  FIG. 13 shows an example of a functional block diagram of the image forming apparatus 20 of the present embodiment. The functional block diagrams of the management device 40, the sales server 60, and the information terminal 10 are the same as those in the first embodiment. Moreover, since the component which attached | subjected the same code | symbol in FIG. 5 fulfill | performs the same function, only the main components of a present Example may be mainly demonstrated.

図１３の画像形成装置２０の記憶部２０００には、表６に示されているような出力可能枚数テーブルによって構成されている出力可能枚数管理ＤＢ２００５が構築されている。出力可能枚数テーブルには、機種ごとに連続出力速度及び出力可能枚数が対応づけて登録されている。機種は、画像形成装置２０の種別を示す識別情報である。連続出力枚数は、それぞれの画像形成装置の出力能力を意味し連続して印刷した場合の印刷速度である。出力可能枚数は、送信回数がリトライ回数を超えてからそれぞれの画像形成装置２０が出力可能なページ数である。出力可能枚数は、連続出力速度が大きいほど出力可能枚数が大きくなっている。これにより、画像形成装置２０の連続出力速度が大きくても、ある程度の時間を猶予期間としてユーザは画像形成装置２０を使用できる。

In the storage unit 2000 of the image forming apparatus 20 in FIG. 13, an outputable number management DB 2005 configured by an outputable number table as shown in Table 6 is constructed. In the outputtable number table, the continuous output speed and the number of outputtable sheets are registered in association with each model. The model is identification information indicating the type of the image forming apparatus 20. The continuous output number means the output capability of each image forming apparatus and is the printing speed when printing is performed continuously. The outputtable number is the number of pages that can be output by each image forming apparatus 20 after the number of transmissions exceeds the number of retries. The number of outputtable sheets increases as the continuous output speed increases. Thereby, even if the continuous output speed of the image forming apparatus 20 is high, the user can use the image forming apparatus 20 with a certain period of time as a grace period.

  FIG. 14 shows an example of a flowchart showing the processing procedure of the transmission processing in step S8 of FIG. In the description of FIG. 14, steps different from those in FIG. 12 are mainly described. The processing in steps S10 to S40 is the same as that in FIG.

When the determination in step S40 is Yes, the communication availability determination unit 24 reads the outputable number table from the storage unit 2000 (S41). The communication enable / disable determining unit 24 reads out its own model from the flash memory 303 and the HDD 304, and reads out the outputtable number corresponding to its model from the outputable number table. The subsequent processing is the same as in FIG.
As in the third embodiment, when a certain number of outputs are allowed regardless of the model of the image forming apparatus 20, the grace period is substantially changed between a model with a large continuous output speed and a model with a small continuous output speed. In the present embodiment, the larger the number of sheets that can be output, the larger the number of sheets that can be output, is set in the outputable sheet number table, so that any user of the image forming apparatus 20 can be given a certain grace period.

  Further, in Table 6, “outputtable sheet number ÷ continuous output speed” is not constant, but the outputable sheet number may be set so as to be substantially constant. That is, the number of outputtable sheets is set so that the ratio between the number of outputtable sheets and the continuous output speed is substantially constant.

  The outputtable number management DB 2005 may be held by the image forming apparatus 20 when the image forming apparatus 20 is shipped, or may be downloaded from the management apparatus 40 at a predetermined timing. As this timing, for example, when the image forming apparatus 20 receives a registration status response confirmation from the management apparatus 40, the outputable number management DB 2005 can be downloaded. Or you may download when receiving a use condition response.

  In this embodiment, an image forming apparatus 20 that determines the number of sheets that can be output after the number of transmissions exceeds the number of retries according to the rank of the customer will be described. The customer rank (class) is a relative evaluation between the customer and the customer, which is determined from the customer's creditworthiness, sales to the sales company, and ease of charge collection.

  FIG. 15 shows an example of a functional block diagram of the management device 40 of this embodiment. Note that the functional block diagrams of the image forming apparatus 20, the sales server 60, and the information terminal 10 are the same as those in the first embodiment. Moreover, since the component which attached | subjected the same code | symbol in FIG. 5 fulfill | performs the same function, only the main components of a present Example may be mainly demonstrated.

  The management device 40 of this embodiment has a rank determination unit 45. The rank determination unit 45 is realized by an instruction from the CPU 201 shown in FIG. 3 and determines the rank of the customer. An example of the rank determination method will be described later.

図１５の管理装置４０の記憶部４０００には、表７に示されているようなランク出力可能枚数テーブルによって構成されているランク出力可能枚数ＤＢ４００３が構築されている。ランク出力可能枚数テーブルには、ランクごとに出力可能枚数が対応づけて登録されている。なお、表７ではランクがＡ〜Ｅの５つに区分されているが、これは一例に過ぎず４以下又は６以上のランクに区分してもよい。

In the storage unit 4000 of the management device 40 of FIG. 15, a rank outputable number DB 4003 configured by a rank outputable number table as shown in Table 7 is constructed. In the rank outputtable number table, the number of outputtable sheets is registered in association with each rank. In Table 7, the rank is divided into five ranks A to E, but this is only an example, and the rank may be divided into 4 or less or 6 or more ranks.

  FIG. 16 is an example of a sequence diagram illustrating a procedure in which the image forming apparatus 20 notifies the management apparatus 40 of the usage status Ud and determines the rank. In FIG. 16, steps different from those in FIG. 7 will be mainly described.

  S5.1: When the image forming apparatus 20 is installed, the image forming apparatus 20 transmits a registration confirmation request to the management apparatus 40. On the other hand, the rank determination unit 45 of the management device 40 reads the customer ID associated with the registration number from the device registration information DB 4001. And a customer information request | requirement is transmitted to the sales server 60 with customer ID.

  S5.2: The storage / reading unit 69 of the sales server 60 reads customer information corresponding to the customer ID from the customer management DB 6001. Also, the number of records associated with the customer ID from the contract information DB 6002 is counted. Hereinafter, this count number is referred to as the number of customer contracts. Therefore, the number of contracts is the number of image forming apparatuses 20 for which the customer is currently contracting for rental or the like.

  S5.3: The transmission / reception unit 61 of the sales server 60 transmits customer information, contract information, and the number of contracts to the management apparatus 40.

  S5.4: The rank determination unit 45 of the management device 40 determines the rank of the customer based on the customer information, the contract information, and the number of contracts. The rank determination unit 45 calculates the following total weight by weighting the cumulative payment results of customer information, the contract period of contract information, and the number of contracts.

Total weight = α × cumulative payment record + β × contract period + γ × contracted quantity For example, the median and standard values of the accumulated payment record, the contract period, and the contracted number are determined by the operator of the management apparatus 40 and the weight sum is Α, β, and γ are determined so as to be 50 points. Of course, the weight of the important index may be increased. The total weight of the customer is calculated with the determined α, β, γ.

  The cumulative payment record and the number of contracts are information related to customer credit quality and serve as an index of customer credit quality. The accumulated payment result is information related to sales to the sales company and serves as an index of sales to the sales company. The accumulated payment record and the contract period are information related to the ease of collecting the usage fee and serve as an index of the ease of collecting the usage fee.

Then, customers are ranked by referring to the following table.
100 or more: A rank 80 or more to less than 100: B rank 60 or more to less than 80: C rank 40 or more to less than 60: D rank 40 or less: E rank The rank determining unit 45 is associated with a rank from the rank outputable number table. Read the number of printable images.

  S6: Then, the transmission / reception unit 41 of the management apparatus 40 transmits the number of outputtable sheets to the image forming apparatus 20 together with the registration status response confirmation. The storage / reading unit 29 of the image forming apparatus 20 stores the registration status response confirmation and the number of outputtable sheets in the storage unit 2000. The subsequent processing may be the same as in the first embodiment.

  Processing when the image forming apparatus 20 cannot transmit the usage status Ud is the same as that in FIG. 14 of the fourth embodiment. That is, in step S41, the number of outputtable sheets may be read from the storage unit 2000 instead of the outputtable table.

  In addition, since the rank of a customer can be changed according to the cumulative payment performance, contract period, and number of contracts of each customer, the management device 40 may re-determine the rank once a year, for example.

  The method for determining the rank of the customer is merely an example. The rank may be determined using only one of the customer's cumulative payment record, the contract period, and the number of contracts, or an index other than these may be used.

  In the present embodiment, the management apparatus 40 determines the rank, but the sales server 60 or the image forming apparatus 20 may determine the rank.

  In this embodiment, a description will be given of a print management system 100 in which the management apparatus 40 transmits the upper limit number of prints to the image forming apparatus 20 as a response to the usage status notification process by the image forming apparatus 20.

  In this embodiment, when the image forming apparatus 20 transmits the usage status Ud to the management apparatus 40, the upper limit number of prints held by the image forming apparatus 20 is updated by the management apparatus 40. The upper limit number of prints is the upper limit of the number of pages that can be printed by the image forming apparatus 20 after the upper limit number of prints is updated. Accordingly, the customer can perform printing using the image forming apparatus 20 until the number of printed pages reaches the upper limit number of prints after the image forming apparatus 20 finally transmits the usage status Ud to the management apparatus 40.

  FIG. 17 shows an example of a functional block diagram of the management apparatus 40 and the image forming apparatus 20 of the present embodiment. The functional block diagrams of the sales server 60 and the information terminal 10 are the same as those in the first embodiment. In addition, since components having the same reference numerals in FIG. 5 perform the same function, only the main components of the present embodiment may be mainly described in FIG.

  The management apparatus 40 of this embodiment has a printing upper limit sheet number update unit 46. The printing upper limit sheet number update unit 46 is realized by a command from the CPU 201 shown in FIG. 3 and transmits the upper printing limit sheet number to the image forming apparatus 20 when the usage status Ud is transmitted from the image forming apparatus 20. The maximum number of prints will be described later.

  In addition, the image forming apparatus 20 according to the present exemplary embodiment includes a printing upper limit number DB 2006 in the storage unit 2000.

表８は印刷上限枚数ＤＢ２００６に記憶されている印刷上限枚数テーブルを模式的に示す。Ａ４カラー、Ａ４モノ、Ａ３カラー及びＡ３モノのそれぞれについて印刷上限枚数が登録されている。なお、Ａ４やＡ３などの用紙サイズ、カラーやモノなどの印刷色の区別なしに印刷上限枚数が登録されていてよい。

Table 8 schematically shows a print upper limit sheet number table stored in the print upper limit sheet number DB 2006. The maximum number of prints is registered for each of A4 color, A4 mono, A3 color, and A3 mono. Note that the upper limit number of prints may be registered without distinguishing between paper sizes such as A4 and A3 and print colors such as color and mono.

  As an example, the maximum number of prints for A4 color is 86. A value of 100 in parentheses is a value immediately after the upper limit number of prints is updated by the management apparatus 40. The values in parentheses are values for explanation, and may not be registered in the print upper limit sheet number table. Taking A4 color as an example, the customer can print the remaining 86 sheets. Another form of the upper limit printing number table will be described later.

  The upper limit number of prints may be constant regardless of the customer, or may be different for each customer. When different for each customer, it may be determined at the time of purchasing or renting a product. Alternatively, when different for each customer, the printing upper limit sheet number updating unit 46 determines the number of printing sheets for each customer in consideration. For example, the average, median, mode, maximum, etc. of the difference between the previous usage status Ud and the current usage status Ud are calculated, and for example, the average, median, mode, maximum value, etc. The maximum number of prints is determined to be 2 to 3 times.

  Further, the printing upper limit sheet number updating unit 46 transmits the difference between the previous usage situation Ud and the current usage situation Ud to the image forming apparatus 20, and the image forming apparatus 20 adds this difference to the remaining printing upper limit sheet number. Good. Therefore, the upper limit number of prints of the image forming apparatus 20 is kept constant as in the case where the entire upper limit number of prints is transmitted.

  Returning to FIG. 17, the image forming apparatus 20 according to the present exemplary embodiment includes an upper limit printing number acquisition unit 27 and a remaining number determination unit 28. The printing upper limit number acquisition unit 27 is realized by an instruction from the CPU 301 shown in FIG. 4 and acquires the printing upper limit number transmitted from the management apparatus 40 and stores it in the printing upper limit number DB 2006. As a result, the values in parentheses in Table 8 are obtained. The updated maximum number of prints in the maximum print number table is reduced by the amount printed each time one page is printed or each time one job is completed.

  The remaining number determination unit 28 is realized by an instruction from the CPU 301 and confirms whether the upper limit number of prints is equal to or greater than the total number of pages of the job, or whether the upper limit number of prints is not zero. When the upper limit number of prints is zero, the use restriction unit 26 is notified that use restriction is requested.

  FIG. 18 is an example of a sequence diagram illustrating a procedure for the image forming apparatus 20 to notify the management apparatus 40 of the usage status. Note that FIG. 18 mainly describes the differences (steps S6, S7, S10, and S11) from FIG.

  S6: The transmission / reception unit 41 of the management apparatus 40 transmits a registration status confirmation response to the image forming apparatus 20. In this embodiment, the use upper limit number is transmitted together with the registration status confirmation response.

  S7: The storage / reading unit 29 of the image forming apparatus 20 records the registration status confirmation response 2002 in the storage unit 2000. Further, the printing upper limit number acquisition unit 27 of the image forming apparatus 20 registers the upper limit number of use in the printing upper limit number DB 2006 via the storage / reading unit 29. As a result, the user can use the image forming apparatus 20.

  S10: The transmission / reception unit 41 of the management apparatus 40 transmits a usage status response to the image forming apparatus 20. At least when the use permission 2003 is transmitted, the printing upper limit sheet number updating unit 46 transmits the printing upper limit sheet number to the image forming apparatus 20.

  S11: The transmission / reception unit 21 of the image forming apparatus 20 receives the use status response (use permission 2003) and the upper limit number of prints. As a result, the storage / reading unit 29 of the image forming apparatus 20 stores the use permission 2003 in the storage unit 2000. Further, the printing upper limit number acquisition unit 27 of the image forming apparatus 20 registers the upper limit number of use in the printing upper limit number DB 2006 via the storage / reading unit 29. Therefore, when the usage status Ud is periodically transmitted to the management device 40, the upper limit number of usage is also periodically updated.

  FIG. 19 is an example of a flowchart illustrating a procedure in which the image forming apparatus 20 updates the upper limit number of prints. The process of FIG. 19 starts when, for example, it is time to execute the usage status notification process.

  First, the usage status transmission unit 25 of the image forming apparatus 20 transmits the usage status Ud to the management device 40 (S10).

  The transmission / reception unit 21 of the image forming apparatus 20 receives the usage status response and the upper limit number of prints (S20). The upper limit number of prints may be transmitted only when the use permission 2003 is transmitted. This is because, when “unusable” is transmitted, the customer cannot print even if the upper limit number of prints is updated. However, since the customer cannot print when unavailable is transmitted, the upper limit number of prints may be transmitted when unavailable is transmitted.

  The use restriction unit 26 determines whether or not printing is not permitted (S30).

  If the determination in step S30 is Yes, the use restriction unit 26 restricts use of the image forming apparatus 20 (S50).

  If the determination in step S30 is No, since the upper limit number of prints has been received, the upper limit print number acquisition unit 27 updates the upper limit number of prints in the print upper limit number DB 2006 (S40).

  As described above, when the use is not restricted, the upper limit number of prints is updated, so that the customer can print within the range of the upper limit number of prints.

  FIG. 20 is a flowchart illustrating an example of a procedure in which the image forming apparatus 20 checks the upper limit number of prints during printing and updates the upper limit number of prints. The processing in FIG. 20 is started, for example, when the user performs an operation for executing a job (print or copy) for printing.

  First, the remaining number determination unit 28 refers to the print upper limit number DB 2006 and determines whether the upper limit print number is equal to or greater than the total number of pages (S10). In the case of a print job, since the total number of pages to be printed is known in advance, it can be easily determined whether the upper limit number of prints is equal to or greater than the total number of pages. In the case of a copy job, the total number of pages to be printed cannot be determined unless the number of documents is known. Therefore, the remaining number determination unit 28 calculates the total number of pages using the number of documents counted by scanning the document with a scanner device or the like, and determines whether the upper limit number of printing is equal to or more than the total number of pages. Even if the upper limit number of prints is less than the total number of pages, printing may be permitted until the upper limit number of prints becomes zero. In this case, since a part of the job may be sufficient, it is preferable that the user inputs to the image forming apparatus 20 that printing is to be performed. This is because the user wants to print the entire job, and printing a part of the job may be meaningless. Also in this case, the image forming apparatus 20 can execute a job within the range of the current upper limit number of prints.

  Further, instead of comparing the total number of pages of the job with the upper limit number of prints, the remaining number determination unit 28 may determine whether the upper limit number of prints is zero every time one page is printed. In this case, the image forming apparatus 20 executes the job until the upper limit number of prints becomes zero.

  When the upper limit number of prints is registered in the upper limit print number DB 2006 according to the paper size or print color, the upper limit number of prints and the total number of pages of the job that meet the print conditions (paper size or print color) set by the user. Alternatively, it is determined whether or not the upper limit number of prints that meets the printing conditions is zero.

  If the determination in step S10 is Yes, the use restriction unit 26 does not restrict use, so the image forming apparatus 20 executes the job (S20).

  Next, the usage frequency recording unit 23 updates the upper limit number of prints (S30). As described above, it may be updated when one job is completed, or may be updated for each page.

  If the determination in step S10 is No, the use restriction unit 26 cancels the job (S40). As described above, a job is canceled in a case where the job is canceled without being executed at all, or a case where a part of the job is executed but the rest is canceled.

  When the job is canceled, the image forming apparatus 20 preferably displays an error message on the operation unit 307 or the like. For example, if a job is canceled without being executed, “Job canceled” is displayed. If a part of the job is executed, “Job canceled. Page not printed” Is displayed. " Thereby, the user can grasp the reason why the job is canceled and the number of pages not printed.

  As described above, according to the print management system 100 of this embodiment, the customer user can use the image forming apparatus 20 until the upper limit number of prints is exceeded. If the usage status notification is made periodically (for example, once a day), the upper limit number of prints is also periodically updated. Therefore, it is unlikely that the upper limit number of prints becomes zero and the use of the image forming apparatus 20 is restricted. When the user prints a large amount in a short time, the use of the image forming apparatus 20 may be restricted. In such a case, the user can operate the image forming apparatus 20 to transmit the usage status Ud to the management apparatus 40, whereby the upper limit number of prints can be updated.

  FIG. 21 is an example of a flowchart illustrating a procedure performed by the management apparatus 40 when use is restricted because the upper limit printing number of the image forming apparatus 20 has become zero.

  The use restriction unit 26 of the image forming apparatus 20 transmits use restriction occurrence information via the transmission / reception unit 21 (S10). The use restriction occurrence information is information indicating that the use restriction has occurred because the upper limit number of printing sheets has become zero. The usage restriction occurrence information may be transmitted together with the usage status Ud, or may be transmitted alone.

  For example, when the management device 40 receives the usage status Ud (No in S10), the printing upper limit number update unit 46 calculates the average, median, mode, and maximum of the difference between the previous usage status Ud and the current usage status Ud. A value or the like is calculated using the past N times (N is a natural number of 2 or more) (S40). Then, an average, median, mode, maximum value, etc., 2 to 3 times, etc. are determined as the maximum number of prints. Therefore, the upper limit number of prints may be increased or may be passed, and is always kept at an appropriate value.

  When the management apparatus 40 receives only the usage status Ud (No in S10), the printing upper limit sheet number updating unit 46 determines that it is preferable to increase the printing upper limit sheet number because the use is restricted, and the use restriction occurs. The upper limit number of prints is calculated using the current printing speed (S20). When the usage restriction occurrence information is transmitted, since the printing can be performed only up to the upper limit number of prints, the appropriate upper limit number of prints for this customer is not clear. Therefore, an appropriate upper limit number of prints is estimated using the printing speed. For example, when use restriction occurrence information is received within 12 hours from the update of the upper limit number of prints, “upper limit number of prints at update time / 12” is the printing speed per hour. If the update interval of the upper limit number of prints is 24 hours, “upper limit number of prints at update time / 12” × 24 is the estimated upper limit number of prints.

  Further, even if usage restriction occurrence information is transmitted, the upper limit number of prints is not changed immediately, and printing is performed when the number of times that usage restriction occurrence information is transmitted in a unit period (for example, one week or January) is equal to or greater than a threshold value The upper limit number of sheets may be increased.

  In this way, by setting the upper limit number of prints with less excess or deficiency, it is possible to prevent the customer from continuing to use the image forming apparatus 20 that does not transmit the usage status Ud.

  Note that the use restriction occurrence information may be transmitted to the management apparatus 40 before the upper limit number of prints becomes zero. For example, when 80% to 90% of the upper limit number of prints is consumed, the image forming apparatus 20 transmits use restriction occurrence information to the management apparatus 40. In this case, the period during which the customer cannot use the image forming apparatus 20 can be eliminated or shortened by calculating the upper limit number of prints as in step S20 of FIG.

<Another example of the upper limit printing number table>
Table 8 shows the upper limit number of prints table in which the upper limit number of prints is reduced, but the upper limit number of prints immediately after the update and the count value of the printed pages counted from the previous update are registered in the upper limit number of prints table. May be. In this case, since the count value increases due to the execution of the job, the remaining number determination unit 28 executes the job in a range where the count value is equal to or less than the upper limit number of prints.
