Description

The present invention relates to a printing device, a job transmission device, a maintenance notification method, and a program.

Conventionally, an inkjet printer has been proposed that receives display language data from an external storage device and switches the display language (see, for example, Patent Document 1). With this inkjet printer, the display language can be switched according to the region where the printer is shipped after manufacture.

JP 2005-313332 A

After shipment, printing devices may be moved to other regions where different language areas are used. When a printing device is moved and used, maintenance such as changing the settings to appropriate settings for each region may be required. Examples of appropriate settings include settings that correspond to differences in supply voltage, color profiles, paper settings, etc. If appropriate settings are not performed, the printing device may break down or its functionality (e.g., print quality) may deteriorate.

It is possible to determine that the area in which a printing device is used has changed based on time information obtained from an NTP (Network Time Protocol) server or area information obtained from a GPS (Global Positioning System). However, if the printing device is not connected to an external network and time information cannot be obtained, or if area information cannot be obtained from a GPS, it is not possible to determine that the area in which the printing device is used has changed.

The object of the present invention is to provide a printing device, a job transmission device, a maintenance notification method, and a program that can easily determine if the area of use has changed and prompt for maintenance.

In one aspect, the printing device includes an acquisition unit that acquires, from a received print job, first regional information set in a job transmitting device that transmits the print job, and an alarm unit that issues an alarm urging the user to perform maintenance based on a discrepancy between the first regional information acquired by the acquisition unit and second regional information held by the printing device and indicating the region in which the printing device is used.

According to the above aspect, it is possible to easily determine if the area of use has changed and prompt maintenance.

FIG. 13 is a diagram showing an example of a maintenance notification screen in the first embodiment. 10 is a flowchart for explaining a maintenance notification process in the second embodiment. 13 is a table showing a relationship between a locale ID and a language in the second embodiment.

The following describes a printing device, a job transmission device, a maintenance notification method, and a program according to the first and second embodiments of the present invention, with reference to the drawings.

First Embodiment
FIG. 1 is a block diagram showing a printing system according to the first embodiment.

The printing system shown in FIG. 1 includes a printing device 1 and a user terminal 101.

The printing device 1 includes a medium supply unit 10, a transport unit 20, a printing unit 30, a medium discharge unit 40, a control unit 50, a memory unit 60, an operation panel 70, and a communication unit 80. Although not shown, the printing device 1 may also include a scanner that reads image data from a document.

The media supply unit 10 has a loading platform on which media such as paper is loaded, and supplies the media loaded on this loading platform to the printing unit 30.

The transport unit 20 has, for example, rollers, belts, etc., and transports the medium inside the printing device 1.

The printing unit 30 prints on the medium transported by the transport unit 20. The printing method of the printing unit 30 is not particularly limited, but may be, for example, an inkjet printing method or a stencil printing method.

The medium discharge unit 40 has a loading platform on which media is loaded and is exposed to the outside of the printing device 1, and discharges media that has been printed by the printing unit 30 onto the loading platform.

The control unit 50 has, for example, one or more processors (e.g., CPU: Central Processing Unit) that function as an arithmetic processing device that controls the operation of each part of the printing device 1. This processor functions as the acquisition unit 51 and the notification unit 52 by, for example, reading and executing a predetermined program from the storage unit 60 or from a storage medium (non-transient computer-readable recording medium) that is detachable from the printing device 1.

The acquisition unit 51 acquires, from the print job received by the communication unit 80, the first locale ID set in the user terminal 101 that transmits the print job. This first locale ID is an example of first regional information, and is, for example, an ID that represents the region (language) such as the country of the OS (Operating System) of the job transmission device (user terminal 101) that transmits the print job. This locale ID is, for example, made up of numbers as shown in FIG. 5.

As will be described in more detail later, the notification unit 52 issues a notification urging the user to perform maintenance based on the fact that the first locale ID acquired by the acquisition unit 51 does not correspond to the second locale ID (an example of second regional information) that is held by the printing device 1 and indicates the region in which the printing device 1 is used.

For example, the notification unit 52 may prompt the user to perform maintenance by displaying a maintenance notification screen 71a on the display unit 71 as shown in FIG. 3, which displays the message "Image adjustment may not be appropriate. Please contact the service provider." The notification unit 52 may perform the notification by audio output, or may perform the notification via the communication unit 80 to an external device such as the user terminal 101. The notification unit 52 may also perform the notification to prompt the user to perform maintenance at a predetermined timing based on the start date of use of the printing device 1 stored in the hard disk device of the storage unit 60 (for example, every few years or every few months), or at a predetermined timing based on the number of prints. The notification unit 52 may also perform the notification to prompt the user to perform maintenance based on the fact that the first locale ID and the second locale ID do not correspond to each other at the above-mentioned predetermined timing, or at the timing of other notifications such as when replacing consumables, and perform these notifications simultaneously.

The control unit 50 also changes various settings such as the print settings of the printing unit 30, such as color mode settings, the transport settings of the transport unit 20, and time settings. The control unit 50 also changes the settings manually, such as during maintenance, based on the user's input operation on the input unit 72, and automatically when updating the functions of the printing device 1.

The storage unit 60 includes, for example, a ROM (Read Only Memory), which is a read-only semiconductor memory in which a specific control program is pre-recorded, a RAM (Random Access Memory), which is a semiconductor memory that can be written and read at any time and is used as a working memory area as necessary when the processor executes various control programs, and a hard disk device.

As described below, the storage unit 60 stores a second locale ID, which is held by the printing device 1 and is an example of second regional information indicating the region in which the printing device 1 is used. The storage unit 60 may store this second locale ID in multiple different locations, such as a ROM or a hard disk drive. Note that even if the region in which the printing device 1 is used changes, the second locale ID is retained in the printing device 1 as is. Therefore, when the region in which the printing device 1 is used changes, the second locale ID will indicate the region in which the region of use was used before the change, until it is deleted once.

The operation panel 70 has a display unit 71, which is a display that displays various information, and an input unit 72 that accepts input of various information by a user (e.g., a general user, a maintenance worker, etc.). If the display unit 71 has a touch panel, the display unit 71 also serves as the input unit 72. Note that the maintenance worker may be someone selected from the general users, or may be a specialized maintenance worker.

The communication unit 80 is an interface unit that transmits and receives various information between various devices, such as the user terminal 101, that are connected wirelessly or by wire via the network. The communication unit 80 receives, for example, a print job from the user terminal 101.

The user terminal 101 includes a control unit 110, a storage unit 120, a communication unit 130, a display unit 140, and an input unit 150. The user terminal 101 is an example of a job transmission device. For example, the user terminal 101 is a stationary terminal such as a desktop computer, or a portable terminal such as a tablet terminal, a smartphone, or a notebook computer. The job transmission device is not limited to the user terminal 101, and may be a print control device that controls the printing device 1, or other devices.

The control unit 110 has, for example, one or more processors (e.g., a CPU) that function as an arithmetic processing device that controls the operation of each part of the user terminal 101. This processor controls each part of the user terminal 101 by reading and executing a specific program, such as an OS, from the storage unit 120 or from a storage medium (non-transient computer-readable recording medium) that is removable from the user terminal 101. The control unit 110 may also control the printing device 1 by reading and executing a printer driver.

The storage unit 120 includes, for example, a ROM, which is a read-only semiconductor memory in which control programs are pre-recorded, a RAM, which is a semiconductor memory that can be written and read at any time and is used as a working storage area as necessary when the processor executes various control programs, and a hard disk device in which predetermined programs such as an OS are pre-stored. The locale ID of the OS is the first locale ID as described above.

The communication unit 130 is an interface unit that transmits and receives various information between various devices, such as the printing device 1, that are connected wirelessly or by wire via the network. The communication unit 130 is an example of a transmission unit that transmits a print job to the printing device 1. The first locale ID is incorporated into the print job under the control of the control unit 110.

The display unit 140 is a display that displays various information.

The input unit 150 is, for example, a keyboard device, a mouse device, a touch panel, etc., and accepts input of various operational information by the user.

As described above, the printing device 1 obtains from the received print job the first locale ID (an example of first region information) set in the user terminal 101 (an example of a job sending device) that sends the print job, and issues a notification to encourage the user to perform maintenance based on the fact that the obtained first locale ID does not correspond to the second locale ID (an example of second region information) that is held by the printing device 1 and indicates the region in which the printing device 1 is used. From the viewpoint of the method, the maintenance notification method obtains from the received print job the first locale ID set in the user terminal 101 that sends the print job, and issues a notification to encourage the user to perform maintenance based on the fact that the first locale ID does not correspond to the second locale ID that is held by the printing device 1 and indicates the region in which the printing device 1 is used.

In addition, from the viewpoint of the program, the program causes a computer (e.g., a computer such as the control unit 50 of the printing device 1) to execute a function of acquiring, from a received print job, a first locale ID set in the user terminal 101 that sends the print job, and a function of issuing a notification urging the user to perform maintenance based on a lack of correspondence between this first locale ID and a second locale ID that is held by the printing device 1 and indicates the region in which the printing device 1 is used.

The above-described maintenance notification method and program are executed, for example, by the printing device 1, but may also be executed by another device, such as a dedicated print control device that controls the printing device 1.

Next, the maintenance notification process in this first embodiment will be described with reference to the flowchart shown in FIG. 2. Note that the flowchart shown in FIG. 2 also describes the process when the storage unit 60 of the printing device 1 does not store the second locale ID.

The processing of the flowchart shown in FIG. 2 is performed by the control unit 50 after starting up the printing device 1, for example.

First, the acquisition unit 51 analyzes the print job received by the communication unit 80 (step S11) and acquires the first locale ID included in the print job (step S12).

The acquisition unit 51 may then perform a sampling process (step S13) to check whether the acquisition of the first locale ID satisfies a continuous acquisition condition. The continuous acquisition condition may be, for example, that the same first locale ID is acquired from the print job over a specified period of time or consecutively for a specified number of times or more. The sampling process (step S13) may be omitted, but is preferably performed in order to exclude cases in which a temporarily different locale ID is acquired as the first locale ID. In the sampling process (step S13), the first locale ID does not have to be acquired every time a print job is received.

Next, the acquisition unit 51 determines whether a locale ID (second locale ID) is stored in the storage unit 60 (step S13). If a locale ID (second locale ID) is not stored in the storage unit 60 (step S14: NO), the acquisition unit 51 stores the acquired first locale ID in the storage unit 60 as the second locale ID (step S15). Then, the process shown in FIG. 2 ends.

If a locale ID (second locale ID) is stored in the memory unit 60 (step S14: YES), the notification unit 52 determines whether the first locale ID acquired by the acquisition unit 51 corresponds to the second locale ID stored in the memory unit 60 (e.g., first locale ID ≠ second locale ID) (step S16).

If the first locale ID acquired by the acquisition unit 51 corresponds to the second locale ID stored in the storage unit 60 (step S16: NO), the process shown in FIG. 2 ends.

If the first locale ID acquired by the acquisition unit 51 does not correspond to the second locale ID stored in the storage unit 60 (step S16: YES), the notification unit 52 issues a notification urging the user to perform maintenance (step S17), and the process shown in FIG. 2 ends.

As described above, the notification unit 52 may prompt the user to perform maintenance by, for example, displaying a maintenance notification screen 71a on the display unit 71 as shown in FIG. 3, which displays the message "Image adjustment may not be appropriate. Please contact the service provider."

The user who is prompted to perform maintenance should contact a maintenance technician (service provider), and a specialized maintenance technician should perform the maintenance. If the user who is prompted to perform maintenance is a maintenance technician selected from among general users, the user may perform the maintenance themselves. Note that since the area in which the printing device 1 is used can be said to have changed when maintenance is performed, the second area information (second locale ID) indicating the area in which the printing device 1 is used should be updated by deleting the second area information stored in the printing device 1 and then saving it again in step S15 described above.

The notification unit 52 may also notify the user of the contents of the maintenance to be performed in the area (transmission area) corresponding to the first locale ID set in the user terminal 101, which may be the area to which the printing device 1 is to be moved. The contents of this maintenance may be, for example, the driving voltage of the inkjet head of the printing unit 30, in cases where the supply voltage differs between the areas before and after the movement of the printing device 1. The contents of the maintenance may also be, for example, color adjustment to suit the destination area (for example, color adjustment using a color profile to express the red color unique to China).

If maintenance is not performed even after a predetermined period of time has elapsed since a notification urging the user to perform maintenance was made, the notification unit 52 may issue another notification urging the user to perform maintenance. If maintenance is not performed despite multiple notifications urging the user to perform maintenance, the notification unit 52 may issue a notification by displaying a warning (such as that image quality cannot be guaranteed) during printing, etc., and if maintenance is not performed even after the warning is displayed, the notification unit 52 may perform printing with limited functions of the printing device 1 (for example, printing at a slower print speed or with a lighter print density). The notification unit 52 may also stop the use of the printing device 1. The restriction of functions or the stop of use of the printing device 1 is performed to prevent breakdowns and deterioration of quality.

When the difference in the setting conditions (e.g., the difference in the head drive voltage) that should be performed during maintenance due to a change in region of the printing device 1 is equal to or greater than a predetermined value, it is preferable to restrict or suspend the functions of the printing device 1 earlier than when the difference is less than the predetermined value. Furthermore, when maintenance is not required, the notification unit 52 may omit the notification process for the execution of maintenance.

In the above description, the locale ID has been described as an example of the first region information and the second region information, but the first region information and the second region information are not limited to the locale ID. For example, the first region information may be a locale ID, and the second region information may be information other than the locale ID. In addition, the region represented by the first region information (first locale ID) and the region represented by the second region information (second locale ID) can be said to correspond even if there is a difference in how the region is perceived, as long as they include a common region, such as when one is regional information representing Tokyo and the other is regional information representing Japan. In addition, the user terminal 101 (the communication unit 130, which is an example of a transmission unit) which is an example of a job transmission device does not transmit a print job to the printing device 1, but may transmit an execution job other than a print job to an execution device other than the printing device 1. Incidentally, when the region of use of the execution device is changed, the language setting is usually set to that of the destination. The user terminal 101 includes language information in the execution job and sends it to the execution device. Therefore, after changing the language setting, the execution device should check the language information of the multiple execution jobs sent, and if the most common language information matches the language information of the language setting set on the execution device, determine that the area in which the execution device is used has changed. This makes it easy to determine that the area in which the execution device is used has changed, and prompts maintenance to be performed.

The processes in the flowchart shown in FIG. 2 (for example, the process of acquiring the first locale ID after analyzing the print job in steps S11 and S12 described above, and the process of determining the correspondence between the first locale ID and the second locale ID in step S16 described above) may be performed at any timing, such as every time a print job is received a specified number of times, rather than every time a print job is received. In this case, the control of the control unit 50 can be simplified.

In the first embodiment described above, the printing device 1 includes an acquisition unit 51 that acquires, from a received print job, a first locale ID, which is an example of first regional information set in the user terminal 101, which is an example of a job transmission device that transmits the print job, and a notification unit 52 that issues a notification urging the user to perform maintenance based on a lack of correspondence between the first locale ID acquired by the acquisition unit 51 and a second locale ID, which is an example of second regional information that is held by the printing device 1 and indicates the region in which the printing device 1 is used.

The user terminal 101, which is an example of a job transmission device, includes a communication unit 130, which is an example of a transmission unit that transmits a print job (an example of an execution job) to the printing device 1 (an example of an execution device), and a storage unit 120 that stores a first locale ID, which is an example of first regional information set in the user terminal 101, and the communication unit 130 transmits a print job including the first locale ID to the printing device 1.

The maintenance notification method is, for example, a maintenance notification method performed by the printing device 1, and obtains from the received print job a first locale ID, which is an example of first regional information set in the user terminal 101, which is an example of a job transmission device that transmits the print job, and issues a notification urging the user to perform maintenance based on the fact that this first locale ID does not correspond to a second locale ID, which is an example of second regional information held by the printing device 1 and indicates the region in which the printing device 1 is used.

The program also causes a computer (e.g., a computer such as the control unit 50 of the printing device 1) to perform the following functions: obtain, from the received print job, a first locale ID, which is an example of first regional information set in the user terminal 101, which is an example of a job transmitting device that transmits the print job; and issue a notification to encourage the execution of maintenance based on a lack of correspondence between the first locale ID and a second locale ID, which is an example of second regional information that is retained by the printing device 1 and indicates the region in which the printing device 1 is used.

Therefore, for example, based on the fact that the first locale ID set in the user terminal 101 that sends the print job does not correspond to the second locale ID that indicates the region of use of the printing device 1, it is possible to determine that the printing device 1 has been moved to a different region and is being used. This makes it possible to easily determine that the region of use has changed even when time information cannot be obtained from an NTP server or region information cannot be obtained from a GPS or the like. Furthermore, since it is possible to determine that the region of use of the printing device 1 or the like has changed, it is possible to prompt the user to perform maintenance that is required in response to the change in the region of use at an appropriate timing and with appropriate content. Thus, according to this first embodiment, it is possible to easily determine that the region of use has changed and prompt the user to perform maintenance.

In addition, in this first embodiment, the notification unit 52 issues a notification to encourage maintenance to be performed based on the fact that the first locale ID acquired by the acquisition unit 51 and that satisfies the continued acquisition condition does not correspond to the second locale ID. This makes it possible to exclude cases in which a temporarily different locale ID is acquired as the first locale ID, and therefore makes it possible to more accurately determine that the printing device 1 has been moved to a different region and is being used. This makes it possible to prevent erroneous notifications of maintenance.

In addition, in this first embodiment, the first region information is the locale ID (first locale ID) of the OS of the user terminal 101, which is an example of a job transmission device that transmits the print job. In this way, by using information on the OS of the user terminal 101 (job transmission device), it is more likely that the first region information is the transmission region of the user terminal 101, so it is possible to more accurately determine whether the printing device 1 has been moved to a different region and is being used. Therefore, false notifications of maintenance can be prevented.

Second Embodiment
The second embodiment differs from the first embodiment in that a notification is issued to prompt the user to perform maintenance not only because the first region information (first locale ID) and the second region information (second locale ID) do not correspond to each other, but also because the first language information related to the second region information and the second language information in the language setting of the printing device 1 do not correspond to each other, but other matters can be the same as those in the first embodiment. Therefore, only the differences will be described.

Figure 4 is a flowchart for explaining the maintenance notification process in the second embodiment.

The flowchart shown in FIG. 4 is similar to the flowchart shown in FIG. 2, except that in addition to the processing of the flowchart shown in FIG. 2, the processing of steps S21 and S22 is performed. Therefore, only matters related to the processing of steps S21 and S22 will be described.

As described above, if the first locale ID acquired by the acquisition unit 51 does not correspond to the second locale ID stored in the storage unit 60 (step S16: YES), the notification unit 52 converts the second locale ID into first language information (e.g., information in the language shown in FIG. 5) (step S21). For example, as shown in FIG. 5, if the second locale ID is 1041, the first language information becomes Japanese information.

Then, the notification unit 52 determines whether the above-mentioned first language information corresponds to the second language information of the language setting of the printing device 1 (step S22). For example, the second language information of the language setting of the printing device 1 is Japanese information if the language setting is Shift_JIS, and is Chinese information if the language setting is Unicode (UTF-8).

As an example, consider the case where the second locale ID is 1041 (Japan) and the language associated with this second locale ID is Japanese, as shown in FIG. 5. In this case, if the language setting of the printing device 1 is Shift_JIS, the second language information is Japanese information, and therefore the notification unit 52 determines that the first language information (Japanese) associated with the second locale ID corresponds to the second language information (Japanese) in the language setting of the printing device 1 (step S22: NO). On the other hand, if the language setting of the printing device 1 is Unicode (UTF-8), the second language information is Chinese information, and therefore the notification unit 52 determines that the first language information (Japanese) associated with the second locale ID does not correspond to the second language information (Chinese) in the language setting of the printing device 1 (step S22: YES).

If the first language information and the second language information correspond to each other (step S22: NO), the process shown in FIG. 4 ends. If the first language information and the second language information do not correspond to each other (step S22), the notification unit 52 issues a notification to encourage the user to perform maintenance (step S17), as described above, and the process shown in FIG. 4 ends.

The correspondence between the first language information and the second language information (step S22: NO) may be a condition for saving in the process of saving the first locale ID as the second locale ID (step S15) as described above. In other words, since the second locale ID saved in the printing device 1 represents the region in which the printing device 1 is used, the condition for saving may be that it corresponds to the second language information of the language setting of the printing device 1.

The second embodiment described above can achieve the same effects as the first embodiment described above, namely, it can easily determine that the area in which the printing device 1 is used has changed and prompt for maintenance.

In addition, in the second embodiment, the notification unit 52 issues a notification to encourage the execution of maintenance based on the fact that the first locale ID (first region information) does not correspond to the second locale ID (second region information) and that the first language information related to the second locale ID does not correspond to the second language information of the language setting of the printing device 1. However, when the region in which the printing device 1 is used is changed, the language setting of the printing device 1 is usually changed as well. Therefore, when the language setting of the printing device 1 is not changed (i.e., when the second language information of the language setting of the printing device 1 corresponds to the first language information related to the second region information representing the region in which the printing device 1 is used), it can be considered that the region in which the printing device 1 is used has not changed. Therefore, if the language setting of the printing device 1 is not changed, even if the first locale ID and the second locale ID do not correspond, for example, when a print job (first locale ID) is sent from a user terminal 101 in which first region information (first locale ID) different from the region in which the printing device 1 is used is set, it is possible to prevent a notification that maintenance will be performed. Therefore, it is possible to prevent erroneous notifications of maintenance.

The present invention is not limited to the above-described embodiment as it is, and the components can be modified and embodied without departing from the gist of the invention in the implementation stage. Various inventions can be formed by appropriately combining the multiple components disclosed in the above-described embodiment.
