Description

  The present invention relates to an image forming apparatus capable of double-sided printing using manual paper and an image forming system including the image forming apparatus.

  In an image forming apparatus such as a FAX (facsimile apparatus), a printer, a copying apparatus, and an MFP (composite apparatus), it is difficult to completely avoid the occurrence of a paper jam (medium jam). Therefore, when a paper jam occurs, it is an important technical problem to facilitate the printing restart process after the paper jam is removed. In particular, it is an even more important issue for an apparatus that does not include an automatic duplex printing mechanism and that performs duplex printing using manual paper.

In an image forming apparatus that performs double-sided printing using manual paper, all-page printing is performed only on one side, and then all-page printing is performed on the other side. Therefore, when a paper jam occurs while printing the other side, the print job for one side that has been printed has already disappeared. As a result, when a paper jam occurs while printing the other side, the user returns to the information terminal device that sent the print job to accept the print job on one side after removing the paper jam, and the print It was necessary to generate a job and start the printing process again.

  In a conventional apparatus that performs double-sided printing using manual paper, if a paper jam occurs during printing on the other side as described above, the printing restart process after paper jam removal is large for the user. The problem to be solved that was accompanied by labor burden was left.

According to a first aspect of the present invention, when a user sets a plurality of pages of output media printed on one side using a single-sided printing mechanism to a paper feeding unit, each output medium is fed from the paper feeding unit. An image forming apparatus that prints on the other side of each output medium by a single-sided printing mechanism, and prints a print job for printing on both sides of a plurality of pages of output medium on odd pages of the plurality of pages of output medium The print job and the print job to be printed on the even pages of the multi-page output medium, and print on one side of the multi-page output medium based on one of the print jobs. A printer unit that prints on the other side of the output medium of a plurality of pages set in the paper feed unit based on the other print job, and a user's input of whether or not the jammed medium is used when a paper jam occurs. Accept paper acceptance decision Has a step, when the paper jam during printing execution of the other print job is generated, suspends the other print job, then, the user eliminates a paper jam, the paper usability determining receiving means Usable When the user resets the jammed medium to the paper feed unit, printing of the other print job is resumed on the jammed medium, while the user removes the paper jam and accepts the paper use determination. When the means accepts the unusable, a request is made for a reproduction print job for reproduction printing on both sides of a new output medium set in the paper feed unit, and after the reproduction print job is executed, the other print job is resumed. The main feature is the provision of a jam recovery processing unit.

According to a second aspect of the present invention, when a user sets a plurality of output media printed on one side using a single-sided printing mechanism in a paper feeding unit, each output medium is fed from the paper feeding unit to perform single-sided printing. An image forming apparatus that performs printing on the other side of each output medium by a mechanism, and when a user places a plurality of single-sided originals at a reading position, the image forming apparatus corresponds to the reading order of either even pages or odd pages. The first image is sequentially read from each single-sided document, and then, when the user places a plurality of single-sided documents again at the reading position, the second image is sequentially read from each single-sided document corresponding to the other reading order. In the first copy mode, when the user places a plurality of double-sided originals at the reading position, the first image is sequentially read from one side of the plurality of double-sided originals, and then the user reads a plurality of double-sided originals. When placed again at the reading position, the plurality of both A copy mode selection unit that allows the user to select a second copy mode for sequentially reading the second image from the other side of the document, and a plurality of output media in which each read first image is set in the paper feed unit A printer unit that prints the second read image on the other side of each output medium when the user sets a plurality of output media again in the paper feed unit, during the paper jam occurs, has a paper usability determining receiving means for receiving the usability input of the jam medium from the user, when the paper jam during printing execution to the other surface of the output medium is generated, the print After that, when the user removes the print jam, the paper availability determination accepting means accepts the availability , and the user resets the jammed medium in the paper feeding unit , the jammed medium is placed on the other side of the jammed medium. mark for Was resumed, whereas, the user eliminates a paper jam, the paper usability determining receiving means receiving the disabled, after playing print on both sides of the new output medium set in the paper feed unit, the other surface And a jam recovery processing unit that resumes printing on the printer.

  The first aspect of the invention includes a jam recovery processing unit, and when a paper jam occurs during printing on one side and printing on the other side, a determination is made as to whether or not the print medium being printed can be used (to the user). If it is determined that it can be used, the printing process is resumed. If it is determined that it cannot be used, a reproduction print job for reproducing both sides of the output medium is automatically performed (for the information terminal device). Requesting the user to execute manual double-sided printing based on the reproduction print job (to the user), the printing resumption process after removing the paper jam can be performed without imposing a large labor burden on the user. Get the effect.

  In the second aspect of the invention, in the first copy mode, the single-sided originals of a plurality of pages are placed in a predetermined order, read and printed every other page from the top in the placement order, and stacked and output in the printing order. The multi-page single-sided originals are again placed in the predetermined order, and the remaining read-printed originals of the multi-page single-sided originals are printed on the output medium that is stacked and output in the order of printing. In the second copy mode, one side of each of the plurality of double-sided originals is placed in a predetermined order, read and printed from above in the order of placement, and stacked and output in the reverse order of the printing order. After that, the other side of each of the two-page double-sided originals is again placed in the order opposite to the predetermined order, and printed on the back side of the output medium that is stacked and output in the order of placement reverse to the printing order. Because it is equipped with a scanner unit to output, it is cheaper Even when a print job is generated from read data of a scanner unit using an image forming apparatus that does not have a memory with a large storage capacity, manual duplex printing can be used more effectively. An advantage is obtained in that the printing resumption process after exclusion can be easily executed.

The flow starts when the user issues a print request to the image forming apparatus 100 having the manual duplex printing function from the information terminal apparatus 200.
Step S101
If the print request is manual duplex printing, the process proceeds to step S103. If the print request is normal printing, the process proceeds to step S102.

Step S102
Normal printing processing is executed and the flow is terminated. Here, the normal printing process means, for example, single-sided printing, and the description thereof is omitted because it is a conventionally known technique.

Step S103
The state determination unit 203 determines that the print request is manual duplex printing, transmits a manual duplex print request notification to the image forming apparatus 100 via the network 250, and proceeds to step S104.

Step S104
The job generation unit 201 generates a print job for manual duplex printing from document data, image data, and the like to be printed, and temporarily stores them in the job storage unit 202. Here, the manual duplex printing job includes two pages, an odd page print job including only odd pages to be printed and an even page print job including only even pages to be printed. The reason is that either one of odd-numbered pages or even-numbered pages is sent to the image forming apparatus 100 to complete the printing, and then the paper on which only one side is printed is turned over, and the remaining printing is left. This is because the job is transmitted to the image forming apparatus 100 to complete double-sided printing.

Step S105
As an example, when processing an even page print job first, the information terminal device 200 reads the even page print job from the job storage unit 202 and transmits it to the image forming apparatus 100 via the network 250. Depending on the mechanism of the image forming apparatus 100, the even page print job or the odd page print job is determined first. Here, as an example, it is assumed that an even page print job is transmitted first.

Step S106
If a jam occurrence notification is received from the image forming apparatus 100 via the network 250, the process proceeds to step S107. If the even page print job processing is completed without receiving the jam occurrence notification, the process proceeds to step S108.

Step S107

Step S111
When the state determination unit 203 receives a notification of the result of determining whether or not the sheet can be used from the image forming apparatus 100 via the network 250 and the sheet can be reused, the process proceeds to step S112, and the sheet cannot be reused. If YES, go to step S113.

Step S112
After the user removes the paper jam, the information terminal device 200 executes normal printing resumption processing and returns to step S110.

Step S113
When the state determination unit 203 accepts a print job re-transmission request from the image forming apparatus 100 via the network 250, the job generation unit 201 reproduces the manual double-sided printing process that combines the even and odd pages of the corresponding sheet. A print job is generated and the process proceeds to step S114.

Step S114
The information terminal device 200 transmits a reproduction print job for double-sided printing processing that combines the even-numbered pages and odd-numbered pages of the corresponding paper generated in step S113 to the image forming apparatus 100, and print resumption processing after paper jam removal Is returned to step S110, the printing of all pages is completed while repeating steps S110 to S113, and the flow is terminated.

FIG. 3 is an operation flowchart of the image forming apparatus according to the first exemplary embodiment.
Next, the operation of the image forming apparatus 100 will be described in order of steps from step S201 to step S212 in FIG.

  The flow starts when the power of the image forming apparatus 100 is turned on and a print job can be accepted.

Step S201
When the communication I / F 110 receives a print job requested for printing from the information terminal device 200 via the network 250, the process proceeds to step S202.

Step S202
The input / output information interpretation unit 108 interprets the contents of the received print job. If the print job is a manual duplex printing job, the process proceeds to step S204. If the print job is normal printing, the process proceeds to step S203.

Step S203
Normal printing processing is executed and the flow is terminated.

Step S204
The communication I / F 110 receives an even page print job from the information terminal apparatus 200 via the network. This step is linked to step S105 in FIG.

Step S205
The printer unit 101 executes normal printing processing. If a paper jam occurs during the normal printing process, the paper jam is eliminated based on the normal return method, and a printing resumption process is executed.

Step S206
After all the even pages have been printed, the user puts together the printed sheets on only one side, turns them over, sets them in the paper feed tray, completes the preparation for printing the remaining one side, and presses the panel 109 For example, an odd page print preparation completion notification is transmitted to the information terminal device 200 via the network 250, and the process proceeds to step S207. This step S206 is linked to step S108 of FIG.

Step S207
The communication I / F 110 receives an odd page print job from the information terminal apparatus 200 via the network, and the printer unit 101 starts odd page printing. This step is linked to step S109 in FIG.

Step S208
If the apparatus status monitoring unit 104 does not detect a paper jam until the odd-numbered pages are printed, the flow ends. On the other hand, when the apparatus status monitoring unit 104 detects a paper jam, the process proceeds to step S209.

Step S209
The apparatus state monitoring unit 104 notifies the jam recovery processing unit 107 of the occurrence of a paper jam, and also notifies the jam generation notification via the job management unit 105, the input / output information interpretation unit 108, the communication I / F 110, and the network 250. It transmits to the terminal device 200 and progresses to step S210. This step S209 links to step S110 in FIG.

Step S210
When the jam recovery processing unit 107 asks the user via the panel 109 to determine whether or not the paper corresponding to the paper jam, on which the even-numbered pages have been printed, can be used again Advances to step S211, and upon accepting the determination of non-reusability, advances to step S212.

Step S211
When the user removes the paper jam and then feeds the paper determined to be reusable to the paper feed tray, the jam recovery processing unit 107 includes the input / output information interpretation unit 108, the communication I / F 110, and the network 250. The information terminal device 200 is notified of the paper use availability as a paper use availability determination result notification, and the process proceeds to step S208.

Step S212
If the user determines that the paper cannot be reused after removing the paper jam, the jam recovery processing unit 107 sends the corresponding print data (reproduction print job) to the information terminal device 200 via the network 250. Request retransmission. Further, the user is requested to manually feed double-sided printing with new paper via the panel 109. The communication I / F 110 receives a reproduction print job that prints even and odd sides of the corresponding paper generated by the information terminal device 200. The printer unit 101 prints this reproduction print job on new paper inserted by the user, and the process advances to step S208. Thereafter, Steps S208 to S212 are repeated, and if the apparatus state monitoring unit 104 does not detect a paper jam until odd-numbered page printing is completed, the flow ends.

  As described above, according to the present embodiment, when a paper jam occurs while printing the other side, the user can execute the print job to accept the print job on one side after removing the paper jam. There is no need to return to the sent information terminal device, generate the print job, and activate the printing process again. As a result, it is possible to reduce the labor of the printing resumption process for the user after removing the paper jam.

  In the first embodiment, a print job is temporarily stored in the job storage unit 202 of the information terminal device 200. After printing one side, a paper jam occurs during printing the other side, and the paper is reused. If it is determined that the job cannot be performed, the job generation unit 201 reads the printed job for one side again from the job storage unit 202 and regenerates the corresponding non-reusable paper. A replay print job is generated.

  However, when the print job is generated from the read data of the scanner unit, the job storage unit 202 of the information terminal device 200 cannot be used as described above. In addition to the functions of the first embodiment, the image forming apparatus of the present embodiment can easily generate a reproduction print job for manual printing even when a print job is generated from read data of the scanner unit.
