When an error occurs to interrupt a submitted job in process, the image forming apparatus notifies the control apparatus or the external apparatus about the job interruption, and controls the interrupted job by page, according to the instruction.

Description

  The present invention relates to an image forming system, a control apparatus, an image forming apparatus, a control method thereof, and a program for transferring print data generated in a host computer to an image forming apparatus for printing.

  In an image forming apparatus equipped with a finisher such as a stacker, when a large amount of continuous printing is performed in a mode using the finisher, an abnormality may occur in an image printed on paper for some reason. However, it is not easy to check the printing status of paper stored in a finisher such as a stacker. Therefore, when the continuously printed paper is taken out after the printing is finished, an abnormality is first noticed, and equipment such as paper may be wasted.

  In Patent Document 1, in order to check print quality degradation that may occur due to printing interruption, the apparatus automatically performs sample printing (also referred to as sample printing, confirmation printing, confirmation printing, etc.) when restarting after printing interruption. An image forming apparatus has been proposed. In addition, a jam recovery function that automatically resumes printing from the next page without a print instruction from the host computer after the user removes the paper remaining in the device due to the occurrence of a paper jam. There is also an image forming apparatus having In this jam recovery function, printing is resumed from the next page of the page that has been normally printed and discharged, so that the printing after the page corresponding to the remaining paper can be performed again.

  However, the above prior art has the following problems. For example, whether or not a print quality deterioration check by sample printing is actually required depends on the situation and the user. If the image forming apparatus automatically performs sample printing, extra time and paper are consumed unless the user particularly desires.

  Further, there is a demand for not only whether to perform sample printing, but also for the user to flexibly and instruct the entire operation of the image forming apparatus performed when resuming after printing is interrupted depending on the situation. For example, the paper (jam remaining paper) remaining in the apparatus without being discharged out of the image forming apparatus when interrupted by a jam may be of sufficient quality to be used depending on the situation. There is a demand for the user to determine whether or not to use the remaining paper as it is by actually viewing the paper on the spot. For example, a sheet that has passed through the fixing device and has undergone a desired print and that is judged to have no quality problem with no particular wrinkles or folds may be used as it is as a printed matter. In addition, when printing printed materials that are confusing when there are multiple identical items, such as invoices, there is a case where the remaining paper that does not have a quality problem is not discarded but is actively used. Conceivable.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a mechanism that allows a user to instruct each page about an operation when resuming printing interrupted due to an error.

  The present invention is an image forming system including an image forming apparatus and a control apparatus that receives a job from an external apparatus and inputs the received job to the image forming apparatus. When a job being executed is interrupted, a display control unit that displays a screen for instructing control of each page of the interrupted job, and a page of the interrupted job via the screen displayed by the display control unit A receiving unit that receives a user instruction for each job, and an instruction unit that notifies the image forming apparatus of an instruction for each page of the interrupted job according to the user instruction received by the receiving unit. If an error occurs that interrupts the job while it is being executed, the job interruption occurrence notification is And interrupt occurrence notification means for notifying location, in accordance with an instruction from said instruction means, characterized in that it comprises a control means for controlling the job the interruption for each page.

  According to another aspect of the present invention, there is provided a control device that accepts a job from an image forming apparatus and an external device, and inputs the accepted job to the image forming apparatus, and a job being executed in the image forming apparatus is interrupted. Display control means for displaying a screen for instructing control for each page of the interrupted job; and reception means for receiving a user instruction for each page of the interrupted job via the screen displayed by the display control means; And instructing means for notifying the image forming apparatus of an instruction for each page of the interrupted job in accordance with the user instruction received by the accepting means.

<Configuration of Printer Unit 202>
Next, the configuration of the printer unit 202 will be described with reference to FIG. The polygon mirror 701 receives four laser beams emitted from the semiconductor laser driving unit. One of the laser beams scans the photosensitive drum 705 through mirrors 702, 703, and 704. Another laser beam scans the photosensitive drum 709 through mirrors 706, 707, and 708. Further, another laser beam scans the photosensitive drum 713 through mirrors 710, 711, and 712. Further, another laser beam scans the photosensitive drum 717 through the mirrors 714, 715 and 716.

  On the other hand, the developing device 718 supplies yellow (Y) toner, and develops the latent image formed on the photosensitive drum 705 in accordance with the scanning of the laser beam to form a yellow toner image. The developing device 719 supplies magenta (M) toner, and develops the latent image formed on the photosensitive drum 709 in accordance with the scanning of the laser beam to form a magenta toner image. The developing device 720 supplies cyan (C) toner and develops the latent image formed on the photosensitive drum 713 in accordance with the scanning of the laser beam to form a cyan toner image. Further, the developing device 721 supplies black (B) toner, and develops the latent image formed on the photosensitive drum 717 in accordance with the scanning of the laser beam to form a black toner image. The toner images of the above four colors (Y, M, C, K) are transferred to a sheet, and a full color output image can be obtained.

  A sheet fed from any one of the sheet cassettes 722 and 723 and the manual feed tray 724 is adsorbed onto the transfer belt 726 via a registration roller 725 and conveyed. In synchronism with the timing of paper feeding, toner of each color is developed in advance on the photosensitive drums 705, 709, 713, and 717, and the toner is transferred to the sheet as the sheet is conveyed. The sheet on which the toner of each color is transferred is separated from the transfer belt 726 and conveyed to the fixing device 728 by the conveyance belt 727. In the fixing device 728, the toner is fixed on the sheet. The sheet that has passed through the fixing device 728 is once guided downward by the flapper 729, and after the trailing edge of the sheet has passed through the flapper 729, the sheet is switched back and discharged. As a result, the sheets are discharged in a face-down state, and the correct page order is obtained when printing is performed sequentially from the first page.

  The four photosensitive drums 705, 709, 713, and 717 are arranged at equal intervals with a distance d, and the sheet is moved at a constant speed v (however, the moving speed of the first mirror unit 510 of the scanner unit) by the conveyance belt. v). The polygon mirror 701 and the semiconductor laser are driven so that a toner image is formed on the photosensitive drum in synchronization with the timing according to the positional relationship and the conveyance speed.

<Configuration of Finisher 205>
Next, a configuration example of the finisher unit 205 will be described with reference to FIG. The sheet discharged through the fixing device 728 of the printer unit 202 is conveyed to the finisher unit 205. The finisher unit 205 includes a sample tray 801 and a stack tray 802, and the discharge destination tray is switched according to the type of job and the number of discharged sheets.

  There are two sorting methods. One is a bin sorting method that uses a plurality of bins to distribute output sheets to each bin for each job. The other one is an electronic sorting function, which will be described later, and a shift sorting method in which bins (or trays) are shifted forward in FIG. 8 and output sheets are sorted for each job. The electronic sort function is called collate. If the above-mentioned in-device controller 204 has a large-capacity memory (for example, the image memory 304 and the HDD 305), a so-called collate function that changes the buffered page order and discharge order using this memory can be used. Supports electronic sorting functions. Note that the group function is a function for sorting by page, while sorting is sorted by job.

  Further, when discharging to the stack tray 802, it is also possible to store the sheets before being discharged for each job and bind them by the stapler 805 immediately before discharging. In addition to the above two trays, there are a Z-folder 804 for folding paper into a Z-shape and a puncher 806 for punching two (or three) holes for files, depending on the type of job. Each process.

  Further, the saddle stitcher 807 binds the central portion of the sheet at two places, and then folds the sheet in half by biting the central portion of the sheet with a roller, and performs a process of creating a booklet such as a weekly magazine or pamphlet. . The sheets bound by the saddle stitcher 807 are discharged to the booklet tray 808.

  In addition, although not shown in FIG. 8, the image forming system 100 includes binding by glue (glue) for bookbinding, or trim (cutting) for aligning the end surface opposite to the binding side after binding. It is also possible to add a finisher. The inserter 803 is for sending a sheet set on the tray 809 to one of the trays 801, 802, and 808 without passing through the printer. As a result, the sheet set in the inserter 803 can be inserted (inserted) between the sheets fed into the finisher unit 205. On the tray 809 of the inserter 803, sheets to be inserted are set face-up by the user, and are fed into the finisher unit 205 in order from the uppermost sheet by the pickup roller 810. Accordingly, the sheet from the inserter 803 is conveyed to the trays 801 and 802 as it is, and is discharged in a face-down state. When the recording paper is sent to the saddle stitcher 807, the recording paper is once sent to the puncher 806 side, and then the face is aligned by switching back and sending it.

<External controller 104>
Next, the configuration of the external controller 104 and the operation during printing will be described with reference to FIG. The external controller 104 includes a CPU 901, a work memory 902, an image processing unit 903, an image memory 904, a mass storage device (hereinafter referred to as HDD) 905, an external network I / F unit 906, an internal network I / F unit 907, and an operation unit. 913.

  The operation unit 913 provides a user interface. In other words, the operation unit 913 includes an input device for the user to instruct execution of the function of the external controller 104 and to perform operation setting at the time of function execution. The operation unit 913 includes a display device for notifying the user of the state of the external controller 104.

  The image processing unit 903 is connected to the image forming apparatus 101 via the video cable 103. The image processing unit 903 is also connected to the image memory 904. The external network I / F unit 906 is connected to the external network 105, and the internal network I / F unit 907 is connected to the internal network 102. The CPU 901 operates according to a program stored in the HDD 905, communicates with the computer terminal 106 and the image forming apparatus 101 via the network I / F units 906 and 907, and executes predetermined processing. In addition, the CPU 1901 performs a user instruction / status display process from the operation unit 203.

  Next, an operation (control of the CPU 901) in the external controller 104 when printing a document file on the computer terminal 106 will be described. The external controller 104 receives the PDL data transmitted from the computer terminal 106 using the external network I / F unit 906 via the external network 105. The PDL data received by the external network I / F unit 906 is stored in the HDD 905. Next, the CPU 901 uses the image processing unit 903 to develop the PDL data stored in the HDD 905 as an image on the image memory 904. Then, the image processing unit 903 transfers the developed image to the image forming apparatus 101 via the video cable 103. At this time, the CPU 901 transmits the print attribute information of the developed image to the image forming apparatus 101 via the internal network I / F unit 907 and the internal network 102. Note that the print attribute information includes information such as the size of the developed image, settings at the time of printing performed by the image forming apparatus 101 included in the PDL data, and the like. Thus, based on the print attribute information transmitted from the external controller 104 and the developed image, the image forming apparatus 101 prints the image on the sheet.

<Overview of flash function sequence example>
Next, with reference to FIG. 4A and FIG. 4B, an outline sequence example of processing for the characteristic flash function in the present embodiment will be described. 4A and 4B show an example of a processing sequence performed by the external controller 104 and the image forming apparatus 101 in FIG.

  First, FIG. 4A is a sequence example when a 4-page print job is instructed. In the image forming apparatus 101, the discharge of the first page of paper is completed, and after the second page of paper is fed, a job interruption factor (error) occurs before the discharge is completed. The job interruption factor is, for example, jam or no paper. In response to the occurrence of job interruption in the image forming apparatus 101, a flash instruction is issued from the external controller 104. Upon receiving this flash instruction, the image forming apparatus 101 deletes all page data of the job. In other words, the flash process in this example is a process for deleting page data of a job being printed held by the image forming apparatus 101. The external controller 104 that receives the notification of completion of the flash processing from the image forming apparatus 101 inputs the second page sample print in accordance with an instruction from the user. Furthermore, according to the instruction from the user, the second page to the fourth page are instructed again.

  FIG. 4A shows that processing is executed in order from 4001 to 4016. Each process indicated by an arrow indicates that the root side of the arrow is giving an instruction or notification to the tip side of the arrow. Reference numeral 4001 denotes a job start instruction from the external controller 104 to the image forming apparatus 101. Job # 1 is generated in the image forming apparatus 101.

  Subsequently, in 4002 to 4005, a page input instruction is notified from the external controller 104 to the image forming apparatus 101. Here, four pages are input, and four pages of page # 1 to page # 4 are input to the image forming apparatus 101. Thereafter, in 4006, a job interruption occurrence notification is issued from the image forming apparatus 101 to the external controller 104. Here, the image forming apparatus 101 notifies the external controller 104 that some job interruption factor such as no paper or jam has occurred. In step 4007, a flash instruction notification is issued from the external controller 104 to the image forming apparatus 101. This flash instruction corresponds to an instruction transmitted to the image forming apparatus 101 in S5001 of FIG. Details of the flash instruction and the flash process in response to the flash instruction will be described later with reference to FIGS.

  Next, in 4008 to 4011, a page status notification is issued from the image forming apparatus 101 to the external controller 104. The page status notification is a notification indicating the processing status of each interrupted job page. In this example, four times (for four pages) are notified, and this notifies the processing status of each page for four pages entered in 4002 to 4005 of job # 1 that started with the job start instruction of 4001. (S6008 in FIG. 6A). The processing status of each page is one of “printed”, “paper fed”, and “deleted”. “Printed” indicates a processing status in which the page is printed and discharged to a discharge destination such as the stack tray 802 of the finisher unit 205. “Feed” indicates a processing state in which paper is fed from either a sheet cassette or a manual feed tray but is not completed at the discharge destination. That is, it indicates that the sheet of the page exists in the image forming apparatus 101. “Deleted” indicates a processing status in which page data is deleted without the page being fed. The deletion of page data corresponds to the processing of S6007 in FIG.

  In 4008, it is notified that the page # 1 has been printed, and in 4009, it is notified that the page # 2 has been fed but has not been discharged. That is, page # 2 indicates that it remains in the image forming apparatus 101. In addition, 4010 notifies page # 3, and 4011 notifies that page # 4 has been deleted.

  In step 4012, a flash processing completion notification is issued from the image forming apparatus 101 to the external controller 104. In 4013, the page controller (page # 2) is notified from the external controller 104 to the image forming apparatus 101. Here, the discharge destination is instructed as a sample tray, that is, this is an instruction for sample printing (S5106 in FIG. 5B). In response to this, the image forming apparatus 101 sees the result of the sample printing, and the user gives further instructions to the external controller 104.

  In steps 4014 to 4016, a page input instruction is notified from the external controller 104 to the image forming apparatus 101. Three pages are inserted, and three pages of page # 2 to page # 4 are input to the image forming apparatus 101. This means that three pages other than the printed page # 1 among the four pages # 1 to # 4 input in 4002 to 4005 are input in response to a user instruction.

  Through the above sequence, the printout of the four pages of page # 1 to page # 4 and the printout of the sample print of page # 2 are discharged to the sample tray 801 in the image forming apparatus 101. . In FIG. 4A described above, the control when the job end instruction has not been notified for the job input from the external controller 104 to the image forming apparatus 101 has been described.

  However, a job end instruction may be notified. The job end instruction means that page insertion in the job has been completed and no further pages will be input, and therefore the image forming apparatus 101 proceeds with various processes on the premise thereof. For this reason, after page data is deleted by a flash instruction, when a page is input for printing that is to be continued after the flash process, it is necessary to explicitly indicate from the external controller 104 that continuous job input and page input are to be performed. .

  Here, an example of processing when the job end instruction is notified will be described using FIG. 4B as an example in which two jobs are successively input. FIG. 4B is a sequence example when a 4-page print job (job # 1) and a 3-page print job (job # 2) are instructed. Here, after the job end instruction for the first job is notified, the second job starts to be submitted.

  In the image forming apparatus 101, the first and second sheets of job # 1 have been discharged, and a job interruption factor has occurred before the third page is fed. Job # 2 has not fed even one page. The job interruption factor is, for example, no paper. In response to the occurrence of job interruption in the image forming apparatus 101, a flash instruction is issued from the external controller 104. Upon receiving this flash instruction, the image forming apparatus 101 deletes all the page data of the job that has started printing (job # 1) and cancels the job before starting printing (job # 2). In this example, the external controller 104 that has received the notification of completion of the flash processing from the image forming apparatus 101 instructs to input the third and subsequent pages of the first job in accordance with an instruction from the user.

  Since 4101 to 4105 are the same instructions as 4001 to 4005, description thereof is omitted. In 4106, a job end instruction is issued from the external controller 104 to the image forming apparatus 101. Subsequently, in 4107 to 4111, the external controller 104 issues a second job submission instruction to the image forming apparatus 101. Since it is the same as 4101-4108, description is abbreviate | omitted. Here, 4-page job # 1 and 3-page job # 2 are input to the image forming apparatus 101.

  Since 4112-4117 are the same as 4006-4011, description is abbreviate | omitted. Subsequently, in 4118, a job end notification is issued from the image forming apparatus 101 to the external controller 104 (S6004 in FIG. 6A). Here, it is notified that the job # 2 has been terminated by cancellation. Since 4119 is the same as 4012, description thereof is omitted.

  In 4120, a continuous job start instruction (job # 1) is issued from the external controller 104 to the image forming apparatus 101. This continuous job start instruction is an instruction for starting the continuous page input for the job # 1 in which the job itself exists by the flash processing of the image forming apparatus 101. Since job # 1 has once received a job end instruction from 4106, the external controller 104 explicitly instructs the image forming apparatus 101 to start a continuous job so that a continuous page can be input again (in FIG. 5B). S5111). Since it is notified in 4118 that job # 2 has ended due to cancellation, a continuous job start instruction like job # 1 is not issued to job # 2. Since it can be determined that the job # 2 has not been started, it is not necessary to resume the job # 2, and the job # 2 starts again when the job is submitted.

  Since 4121 to 4122 are the same as 4015 to 4016, description thereof is omitted. 4123 indicates a job end instruction for job # 1 as in 4106. As a result, the job end of the job # 1 that has started continuous printing is notified by 4120. Reference numeral 4124 denotes a job end notification from the image forming apparatus 101 to the external controller 104. Here, it is notified that the job # 1 has been normally printed. Thereafter, the job # 2 can be re-submitted from the external controller 104 in accordance with a user instruction.

  As described above, when the flash processing is performed in a state where two jobs that have been instructed to end the job have been input to the image forming apparatus 101, a job that has been printed and has been stopped up to a halfway page is instructed by the user. As a result, the continuation page is reloaded and printed. Also, jobs that have not started printing are cancelled, but can be re-entered and printed according to user instructions.

<Flash instruction and subsequent continuous printing>
Next, the flash instruction of the external controller 104 and the subsequent continuous printing operation will be described with reference to FIGS. 5A and 5B. In the present embodiment, when the external controller 104 receives a job interruption occurrence notification (for example, 4006 in FIG. 4A) from the image forming apparatus 101, the external controller 104 performs the operation described in this flow. The start of this flow is not limited to the reception of a job interruption occurrence notification. For example, there is no problem even if this flow is started by an input from the user to the external controller 104. The processing of each step shown in FIGS. 5A and 5B is realized by the CPU 901 of the external controller 104 loading a control program stored in the HDD 905 into the work memory 902 and executing it.

  When receiving the job interruption occurrence notification from the image forming apparatus 101, the CPU 901 of the external controller 104 transmits a flash instruction to the image forming apparatus 101 in step S5001 (4007 in FIG. 4A). In step S <b> 5002, the CPU 901 receives a page processing status and job end notification from the image forming apparatus 101. The contents of the received notification are stored in the work memory 902 or the HDD 905 and can be referred to when necessary.

  In step S5003, the CPU 901 determines whether a flash completion notification is received from the image forming apparatus 101 (4012 in FIG. 4A). If it is determined that the flash completion notification has not been received, the CPU 901 returns the processing to S5002 again and repeats until it is determined in S5003 that the flash completion notification has been received.

  On the other hand, if the CPU 901 determines in step S5003 that a flash completion notification has been received from the image forming apparatus 101, the process advances to step S5101 in FIG. 5B. In step S <b> 5101, the CPU 901 displays a display for prompting the user to input “continuous printing after job interruption” on the operation unit 913. The display for prompting the user to input “continuous printing after job interruption” will be described later with reference to FIGS. 10A to 10D.

  In step S5102, the CPU 901 determines whether a user input for continuous printing after the job is interrupted is received. As will be described later, when either the print button 1002 or the job cancel button 1001 is pressed, it is determined that the user's input has been accepted.

  The processing of S5102 is periodically repeated until it is determined that the input has been accepted. If the CPU 901 determines that an input has been received in S5102, the process proceeds to S5103. In step S <b> 5103, the CPU 901 determines whether the user has input “job cancel”. If it is determined that the user has input “job cancel”, the CPU 901 advances the process to step S5104. In step S <b> 5104, the CPU 901 transmits a job cancel instruction to the image forming apparatus 101. Then, a series of processing ends.

  On the other hand, if it is determined in step S5103 that the user has not input “job cancel”, that is, if “continue printing” has been input, the process advances to step S5105. In step S <b> 5105, the CPU 901 determines whether the user inputs “sample printing”. If it is determined that the user inputs “print sample”, the process advances to step S5106. In step S5106, the CPU 901 transmits a page to be sample-printed to the image forming apparatus 101 according to the input by the user (4013 in FIG. 4A). In step S <b> 5107, the CPU 901 displays a display for prompting the user to input “continuous printing after sample printing” on the operation unit 913. The display for prompting the user to input “continuous printing after sample printing” will be described later with reference to FIG.

  In step S <b> 5108, the CPU 901 determines whether a user input for continuous printing after sample printing has been received. As will be described later, when either the print button 1102 or the job cancel button 1101 is pressed, it is determined that the user's input has been accepted. Here, S5108 is repeated until it is determined that the input has been accepted. If the CPU 901 determines that an input has been received in S5108, the process proceeds to S5109. In step S <b> 5109, the CPU 901 determines whether the user has input “job cancel”. If it is determined that the user inputs “job cancel”, the CPU 901 advances the process to step S5104, transmits a job cancel instruction to the image forming apparatus 101 as described above, and ends the series of processes.

  On the other hand, if it is determined in step S5109 that the user has not input “job cancel”, that is, if “continue printing” has been input, the CPU 901 advances the processing to step S5110. In step S <b> 5110, the CPU 901 determines whether a job end instruction for the job being submitted has been transmitted to the image forming apparatus 101. If it is determined that the job end instruction has been transmitted, the process advances to step S5112. On the other hand, if it is determined in S5110 that the job end instruction has not been transmitted, the CPU 901 transmits a continuous job start instruction to the image forming apparatus 101 in S5111 (4120 in FIG. 4B). Then, the process proceeds to S5112.

  In step S5112, the CPU 901 focuses on the continuous printing start page input by the user. This is the page that the user has entered on the input screen for continuous printing in the above-described S5102 or S5108. In step S <b> 5113, the CPU 901 transmits a page insertion instruction for the page of interest to the image forming apparatus 101. In step S5114, the CPU 901 determines whether there is a page next to the page of interest. If it is determined that there is a next page, the next page is noticed in S5115 and the process is repeated from S5113. As a result, pages after the start page of continuous printing input by the user are transmitted to the image forming apparatus 101 (4014 to 4016 in FIG. 4A).

  On the other hand, if it is determined in S5114 that there is no next page, it means that the page input instruction for all pages has been transmitted to the image forming apparatus 101. In step S5116, the CPU 901 transmits a job end instruction to the image forming apparatus 101, and completes a series of processes.

  As described above, the CPU 901 of the external controller 104 gives a flash instruction to the image forming apparatus 101. Then, after the flash processing in the image forming apparatus 101 is completed, an operation is performed to transmit to the image forming apparatus 101 a page to be sampled and continuously printed in accordance with an input received from the user.

<Display prompting user to input>
Next, a display in which the CPU 901 prompts the user to input “continuous printing” will be described with reference to FIGS. 10A to 10D and FIG. Here, a screen for instructing control for each page of the interrupted job displayed on the external controller 104 when the image forming apparatus 101 interrupts the job being executed will be described. First, FIGS. 10A to 10D are examples of screens displayed on the operation unit 913 when the CPU 901 prompts the user to input “continuous printing after job interruption”. For example, the screen may be transmitted from the external controller 104 to the computer terminal 106 and displayed on the display unit of the computer terminal 106. Here, the external controller 104 functions as a display control unit and a reception unit. On this screen, the user can instruct control for each page of the interrupted job. The external controller 104 notifies the image forming apparatus of an instruction for each page of the interrupted job in accordance with the received user instruction.

  Here, the continuous printing start page field 1003 indicates from which page the continuous printing starts in the job when the print continuation button 1002 is pressed. The user can change the numeric value of the continuous printing start page field 1003. 10A to 10C illustrate starting continuous printing from the second page, and FIG. 10D starting from the third page.

  The sample printing field 1004 is a check button. When the user presses the button once, the sample printing can be toggled to change whether the sample printing is performed or not. When the field 1004 for sample printing is checked, a page field 1005 for sample printing is also displayed as shown in FIGS. 10A and 10B, and the numeric page is sample printed separately from continuous printing. In this case, a thumbnail of the page to be sample printed is also displayed in the field 1006. Here, the page field 1005 for sample printing can be changed by the user. That is, according to the present embodiment, the continuous printing start page field 1003 and the sample printing page field 1005 are displayed on the screen so that numerical values can be designated by the user. If the field 1004 for sample printing is not checked, the page field 1005 for sample printing is not particularly displayed as shown in FIGS. 10C and 10D. In the field 1006, thumbnails that are sample-printed are not displayed.

  When the job cancel button 1001 is pressed, the CPU 901 notifies the image forming apparatus 101 of a job cancel instruction. When the print continuation button 1002 is pressed, the CPU 901 performs continuous printing processing according to the values indicated in the fields 1003 and 1005. If either the continuation print button 1002 or the job cancel button 1001 is pressed, the input for continuous printing is completed and the user's input is accepted. That is, according to the present embodiment, the screen is displayed so that it is possible to select whether to resume the interrupted job.

  In the case of the example shown in FIG. 4A, in step S5101 in FIG. For example, 2 is displayed as a default value in the start page field 1003 for continuous printing, and 2 is displayed in the page field 1005 for sample printing. The page to be initially displayed is not limited to this example, and any page may be displayed. In this example, since only page # 1 has been printed in the page status notification from the image forming apparatus 101, page # 2, which is the first page that has not been printed, is printed with the continuous printing start page field 1003 and sample printing. The page field 1005 is initially displayed. A field 1006 schematically displays which page is printed when the continuation print button 1002 is pressed. The screen in FIG. 10A indicates that page # 2 is sample-printed, and separately, page # 2 and subsequent pages are continuously printed. That is, when the continuation print button 1002 is pressed on the screen of FIG. 10A, an instruction is given from the external controller 104 to the image forming apparatus 101 in the order of 4013, 4014, 4015, and 4016 as shown in the sequence example of FIG. 4A. Will be.

  For example, if the user wants to change sample printing to page # 1, the page field 1005 for sample printing may be changed to “1” as shown in FIG. 10B. That is, when the print continuation button 1002 is pressed on the screen of FIG. 10B, the instruction 4013 in FIG. 4A changes to page # 1 instead of page # 2. Thereafter, the external controller 104 instructs the image forming apparatus 101 in the order of 4014, 4015, and 4016.

  Furthermore, when the user wants to change to not printing the sample, as shown in FIG. 10C, the field 1004 for sample printing may be unchecked. That is, when the continuation print button 1002 is pressed on the screen of FIG. 10C, the instruction 4013 in the sequence example of FIG. 4A is not notified, and instructions from the external controller 104 to the image forming apparatus 101 in the order of 4014, 4015, and 4016. Will be made.

  Furthermore, if the user wants to change the start of continuous printing from page # 3, the continuous printing start page field 1003 may be changed to “3” as shown in FIG. 10D. That is, when the continuation print button 1002 is pressed on the screen of FIG. 10D, the instruction of 4013 in the sequence example of FIG. 4A is not notified, and instructions are given from the external controller 104 in the order of 4015 and 4016. In the example of FIG. 10D, the paper of page # 2 has passed through the fixing device and has been printed as desired, and has no particular wrinkles or creases, so there is no problem in terms of quality. Is assumed to be unnecessary by the user.

  Next, a screen displayed on the operation unit 913 when the external controller 104 prompts the user to input “continuous printing after sample printing” will be described with reference to FIG. 11. For example, the screen may be transmitted from the external controller 104 to the computer terminal 106 and displayed on the display unit of the computer terminal 106. FIG. 11 is almost the same as FIGS. 10A to 10D, but since the instruction for sample printing has already been completed, only an instruction for continuous printing is possible. FIG. 11 shows a screen displayed in the process of S5107 in FIG. 5B in the situation shown in FIG. That is, in step S5107 in FIG. 5B, the external controller 104 first displays the initial display in FIG. 11 on the operation unit 913 to prompt the user to input. The user can press the subsequent print button 1102 as it is or after changing the start page of continuous printing to a desired page.

  As described above, when the job being executed is interrupted, the user can flexibly specify to which page the sample printing or the continuous printing after the restart is performed. Further, the user can specify whether to execute sample printing or continuous printing.

<Flash processing upon receiving a flash instruction>
Next, the operation of the image forming apparatus 101 when a flash instruction is received will be described with reference to FIGS. 6A and 6B. The processing of each step shown in FIGS. 6A and 6B is executed by the in-device controller 204 of the image forming apparatus 101. More specifically, for example, the CPU 301 of the in-device controller 204 loads the control program stored in the HDD 305 to the work memory 302 and executes it, thereby realizing the processing of FIGS. 6A and 6B.

  In step S6000, the in-device controller 204CPU301 determines whether a flash instruction has been received. The flash instruction is an instruction transmitted from the external controller 104 to the image forming apparatus 101 in S5001 of FIG. If it is determined in S6000 that the flash instruction has been received, in S6001, the CPU 301 pays attention to the first job.

  In step S <b> 6002, the CPU 301 determines whether the job of interest has already been fed one page or more. If it is determined that one or more pages have not been fed, that is, no page has been fed, the CPU 301 advances the process to step S6003. In step S6003, the CPU 301 cancels the job of interest. In step S <b> 6004, the CPU 301 notifies the external controller 104 of job completion (cancellation). In step S6005, the CPU 301 determines whether the processing has been completed for all jobs included in the image forming apparatus 101. If it is determined that processing has not been completed for all jobs, the process advances to step S6006. In step S6006, the CPU 301 pays attention to the next job. Then, the processing from S6002 is executed on the noticed job.

  On the other hand, if the CPU 301 determines in step S6005 that all jobs have been completed, the process advances to step S6009. In step S <b> 6009, the CPU 301 transmits a flash completion notification to the external controller 104. When the external controller 104 receives this flush completion notification, as described above, the external controller 104 advances the process from S5003 to S5101. Then, the process proceeds to S6101 of FIG. 6B.

  On the other hand, if it is determined in S6002 that the job of interest has already been fed one page or more, the CPU 301 advances the process to S6007. In step S6007, the CPU 301 deletes all page data of the job of interest. In step S6008, the processing status of each page of the job of interest is transmitted to the external controller 104. When the processing status notification for each page ends in S6008, the in-device controller 204 advances the processing to S6005, and performs the processing from S6005 onward as described above.

  When the process of S6009 is completed as described above, the process proceeds to S6101 of FIG. 6B. In step S6101, the CPU 301 determines whether a job exists. If there is a job for which printing has been started, that is, a job for which one or more pages have already been fed at the time of S6002, the CPU 301 determines that the job is also present at the time of S6101. If it is determined that no job exists, all jobs have been canceled, and the series of processing ends.

  On the other hand, if it is determined in S6101 that a job remains, the in-device controller 204 advances the process to S6102. In step S6102, the CPU 301 determines whether a job end instruction for an existing job has been received. If it is determined that a job end instruction has not been received, the process advances to step S6110 to determine whether a page input instruction has been received. If it is determined in S6110 that a page insertion instruction has been received, processing of the inserted page is performed in S6111. Then, the process proceeds to S6112.

  On the other hand, if it is determined in S6110 that a page input instruction has not been received, the process advances to S6112. In step S6112, the CPU 301 determines whether a job end instruction has been received. If it is determined that a job end instruction has been received, a series of processing is completed.

  On the other hand, if it is determined in S6112 that the job end instruction has not been received, the CPU 301 returns to S6110 and repeats the process. On the other hand, if it is determined in S6102 that a job end instruction for an existing job has been received, it is determined in S6103 whether a job start instruction has been received. If it is determined that a job start instruction has been received, in step S6104, the CPU 301 recognizes the start instruction for a new job different from the existing job. Therefore, a new job is generated and normal job processing is performed. Then, the process returns to S6103.

  On the other hand, if it is determined in S6103 that a job start instruction has not been received, the CPU 301 determines in S6105 whether a continuous job start instruction has been received. If it is determined that the continuous job start instruction has not been received, the CPU 301 advances the process to step S6106. In step S6106, it is checked whether a job cancel instruction has been received. If it is determined that a job cancel instruction has been received, the process advances to step S6107. In step S6107, the CPU 301 cancels the job and ends the process.

  On the other hand, if it is determined in S6106 that a job cancel instruction has not been received, the CPU 301 returns the process to S6103 and repeats from there. On the other hand, if it is determined in S6105 that the continuous job start instruction has been received, the CPU 301 advances the process to S6108. In step S6108, a new job is generated that inherits a job that has already started printing. In step S6109, the CPU 301 cancels the existing job. Thereafter, the process proceeds to S6110 and the above-described processing is performed.

  As described above, the image forming apparatus 101 performs flash processing for each job in the image forming apparatus in response to a flash instruction from the external controller 104. The flash process is a process that cancels a job before starting printing, deletes the page data of the job while keeping the job that has already started printing without canceling.

  As described above, according to the present embodiment, the external controller 104 operates to issue a flash instruction and a page input instruction according to the user instruction, and the image forming apparatus 101 responds to the flash instruction. Can operate to flash. As a result, the overall operation of the image forming apparatus that is performed when restarting after printing interruption, such as whether to perform sample printing, which page to sample print, and from which page to continue printing depending on the situation. The user can give instructions flexibly.

  Further, the external controller 104 operates to issue a page input instruction in accordance with a user instruction after instructing a continuous job start for a job for which a job end instruction has been issued. The in-device controller 204 of the image forming apparatus 101 operates so as to continuously perform page processing on a printed page in response to a continuous job start instruction. As a result, a continuous page can be reloaded and printed.

  In addition, by issuing a new job start instruction prior to a continuous job start instruction, it is possible to process another new job before printing a continuous page of a stopped job. In the present invention, since it is configured so that printing instructions can be flexibly performed from the host side and the user side, whether or not a print quality deterioration check by sample printing is actually required after resuming printing depends on the situation. It is possible to select according to the user. That is, it is possible to prevent the user from performing sample printing that is not particularly desired and spending extra time and paper.

  Further, the user can instruct the operation of the image forming apparatus in general, which is performed at the time of resumption after the interruption of printing, including whether to perform sample printing, according to the situation. In addition, since the information notification at the time of flash processing is not started for the job that has not started printing, it is only necessary to notify the status of the job once without reducing the total number of notifications. There is also an effect that is good.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. 12 and 13. In the first embodiment, an example in which a print job is developed into an image by the external controller 104 and stored in the HDD of the image forming apparatus 101 has been described. However, the present invention is not limited to this. The image forming apparatus 101 may function as a printer, and the print job sent from the computer terminal 106 may be developed into an image by itself and stored in the HDD. Then, the computer terminal 106 may have a function of performing a flash instruction and subsequent continuous printing. In this case, the external controller 104 can be omitted.

  First, the configuration of the image forming system 100 according to the present embodiment will be described with reference to FIG. The image forming apparatus 101 is a color scanner / printer apparatus capable of full color scanning or printing. The image forming apparatus 101 is connected to the external network 105. A computer terminal 106 is connected to the external network 105. Accordingly, the image forming apparatus 101 is connected to the computer terminal 106 via the external network 105, but is different from the configuration of FIG. 1 in that there is no external controller 104 in between.

  As shown in FIG. 13, the configuration of the in-device controller 102 is almost the same as that in FIG. However, the connection to the computer terminal 106 is not connected to the external controller 104, and the connection to the computer terminal 106 is different via the external network 05. The in-device controller 204 also performs processing of image data handled by the scanner unit 201 and printer unit 202 and data transmission / reception control with the computer terminal 106 connected via the external network 105. Other than that, it is the same as FIG.

  Next, an operation at the time of printing of the in-device controller 204 of the image forming apparatus 101 in the case of a configuration connected to the computer terminal 106 via the external network 105 will be described using FIG. An operation (control of the CPU 301) in the in-device controller 204 when printing a document file on the computer terminal 106 will be described.

  The in-device controller 204 receives the PDL data transmitted from the computer terminal 106 using the network I / F unit 307 via the external network 105. The PDL data received by the network I / F unit 307 is accumulated in the HDD 305. Next, the CPU 301 uses the image processing unit 303 to develop the PDL data stored in the HDD 305 as an image on the image memory 304. The developed image (image data) is stored in the HDD 305 via the image processing unit 303 and the image memory 304. The stored image data is sent again to the printer unit 202 via the image memory 304 and the image processing unit 303 for printing. Thus, the image forming apparatus 101 prints an image on a sheet based on the print attribute information and the developed image.

  As described above, in the present embodiment, the processing performed by the external controller 104 in the above embodiment is performed by the computer terminal 106 and the image forming apparatus 101, thereby omitting the external controller 104. . That is, with this configuration, the computer terminal 106 operates to issue a page input instruction corresponding to the flash instruction and the user instruction instead of the external controller 104. The image forming apparatus 101 expands the received PDL data into an image instead of the external controller 104, and generates image data in a printable format. As a result, the overall operation of the image forming apparatus performed at the time of restart after printing interruption, such as whether to perform sample printing, which page to sample print, and from which page to continue printing, is detailed by the user according to the situation. It is possible to instruct from the computer terminal 106 flexibly.

<Other embodiments>
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads the program. It is a process to be executed.
