[First Embodiment]
A digital printing system according to a first embodiment of the present invention will be described with reference to FIG. In this printing system, a digital printing machine (printing apparatus) 102 and a computer 101 are connected via a network 100. The digital printing machine 102 is a multi-function processing apparatus (Multi Functional Peripheral: MFP (also referred to as an image forming apparatus)) having a plurality of functions, and details of each function will be described below. The digital printer 102 only needs to be able to print in color or monochrome.

  The digital printing machine 102 is configured such that a plurality of apparatuses having different roles are connected to each other to perform complicated sheet processing.

  The digital printing machine 102 can be roughly divided into three parts with the printer unit 1000 as a boundary. In FIG. 1, a device arranged on the right side of the printer unit 1000 is called a paper feeding device, and the main role of the paper feeding device is to continuously transfer sheets stored therein to the printer unit 1000 at appropriate timing. Is to supply. The device also detects the remaining amount of sheets stored inside by a sensor (not shown). There is also a paper feed stage 231 inside the printer unit 1000, and the function equivalent to that of the paper feed device can be executed. These paper feed stages included in the printer unit 1000 are also referred to as a paper feed device in the description. Hereinafter, each part constituting the digital printing machine 102 will be described.

  The printer unit 1000 forms (prints) an image using toner on a medium (sheet) fed from a paper feed stage based on the image data. The configuration and operating principle of the printer unit 1000 are as follows.

  A light beam, such as a laser beam, modulated according to the image data is reflected by a rotating polygon mirror (polygon mirror or the like) and irradiated to the photosensitive drum as scanning light. The electrostatic latent image formed on the photosensitive drum by the laser light is developed with toner, and the toner image is transferred to a sheet pressed against the transfer drum. By sequentially executing this series of image forming processes for yellow (Y), magenta (M), cyan (C), and black (K) toners, a full-color image is formed on the sheet. Further, in addition to these four colors, another color toner called a special color, transparent toner, or the like may be transferred. The sheet on the transfer drum on which the full-color image is thus formed is conveyed to the fixing device. The fixing device includes a roller, a belt, and the like. A heat source such as a halogen heater is built in the roller, and the toner on the sheet on which the toner image is transferred is melted and fixed to the sheet by heat and pressure.

  Next, a program executed by the digital printing machine will be described. These programs are stored in the HDD 209 and read and executed by the CPU 212 of the controller unit 205 of the digital printing machine 102.

  The JDF function program is a program for executing a print function by the controller unit 205 when a JDF job is received by the digital printer 102 via the external I / F 202. Note that JDF is Job Definition Format.

  The PDL function program is a program for executing a print function by the controller unit 205 when data described in PDL is received by the digital printer 102 via the external I / F 202. Note that PDL is Page Description Language.

  The UI function program is a control program for the operation unit 204. The UI function program identifies contents input from the operation unit 204 by the user of the digital printing machine 102, and performs an appropriate screen transition and a processing request instruction to the controller unit 205. Note that the UI means User Interface.

  The sheet management program is a program for executing a management function related to sheets usable by the digital printing machine 102. Sheet related information managed by this program is stored in the HDD 209. In this embodiment, the sheet-related information managed by the sheet management program is data relating to the size, media type, and remaining amount of sheets stored for each paper feed stage (sheet storage unit). Note that the sheet management information is not limited to this, and for example, data related to a sheet name, a sheet basis weight, and the like may be further managed.

  The job hold function program is a program executed by the controller unit 205 when the user of the digital printing machine 102 instructs the execution of the job hold function from the operation unit 204. The job hold function is a function for storing data to be printed in the HDD 209 of the digital printer 102 until a print instruction is received from the user. Thereafter, the user selects data to be printed, and prints data for which a print instruction has been accepted. In the job hold function, the operation of each device such as the printer unit 203, the sheet processing apparatus 200, the HDD 209, the compression / decompression unit 210, and the RAM 208 is performed in an appropriate order by the controller unit 205 based on the processing order and conditions described in the program.

  The mismatch determination program is a function in which the controller unit 205 performs the following determination when the user of the digital printing machine 102 instructs execution of mismatch determination from the operation unit 204. The mismatch determination is whether or not the attribute information (media) of the sheet used in the print job is registered in any of the paper feed stages, and whether or not there is a remaining amount of the sheet to be used in the print job. It is to determine whether or not. The controller unit 205 reads sheet attribute information that can be used by the digital printing machine 102. Note that sheet attribute information that can be used by the digital printing machine 102 is stored in the HDD 209 by the sheet management program. Then, by comparing with the attribute information of the sheet used in the job held by the job hold function program, it is determined whether or not the attribute information of the sheet used in the print job is registered in any paper feed stage. (Hereinafter referred to as “mismatch determination”). The sheet attribute information used in the print job includes at least one of a sheet size, a sheet basis weight, a sheet surface property, a sheet shape, and a sheet color.

  In addition, the controller unit 205 detects the remaining amount of the sheet by a sensor provided in the paper feed stage, and determines whether or not there is a remaining amount of the sheet to be used in the print job (hereinafter referred to as “no remaining amount determination”). Call). The result of mismatch determination (mismatch determination or no remaining capacity determination) executed by this mismatch determination program is held by a flag and stored in the RAM 208.

  Although the details of a part of the function program have been described above, it is not necessary to include all of the function programs, and a part of the function programs or a function program other than those described above may be provided. Details of the mismatch determination (non-match determination or no remaining capacity determination) process will be described later with reference to FIGS. 10, 11, and 12.

  The data structure of the job, print queue data, and hold queue data of the digital printing machine 102 according to the first embodiment will be described with reference to FIG.

  First, the data structure of a job will be described with reference to FIG. A job input to the digital printing machine 102 has a structure of an entry 411 as shown in FIG. There are as many entries 411 as the number of jobs input to the digital printing machine 102 and processed. The entry 411 includes a job ID 411a, a print attribute 411b, print data 411c, and the like. A job ID 411 a in the entry 411 is a unique ID and is used for identifying and specifying a job by the digital printing machine 102. A print attribute defined in the job is stored in the print attribute 411b in the entry 411. As print attributes, the name of the user who submitted the job, the size of the sheet used in the job, the media type, the information on the paper feed stage used in the job, the number of pages, and the like are described. The print data 411c in the entry stores print data that is data describing an image drawn on a print sheet.

  Next, the data structure of the print queue data will be described with reference to FIG. When a job is submitted to the print queue, the job is managed in the print queue buffer 421. When a job is submitted when there is no job in the print queue, the job is registered in the queue 1 of the print queue buffer 421. Next, if a job is input, it is stacked so that it is registered in the queue 2. Printing is basically performed in order from the job stacked in the queue 1. When printing is completed, the job is deleted from the print queue buffer 421, so the jobs in the print queue buffer 421 are moved up in order. Next, the job stacked in the queue 1 is printed. Although only five queues are shown in FIG. 4B, an appropriate number of queues are prepared in consideration of the memory capacity of the digital printing machine 102 and the print processing speed.

  Job attributes registered in each print queue are managed by a print queue job attribute table. In FIG. 4B, in the queue 1 and the queue 5, attribute tables 422 and 423 corresponding to the respective jobs stacked in the print queue buffer 421 are registered. Actually, there are as many queues as the print queue buffer 421. Details of the print queue job attribute table 422 will be described below.

  The attribute table 422 includes a job ID 422a that is an ID for identifying a job, a flag 422b for identifying a mismatch determination result, a flag 422c for identifying whether or not a suspend process target is used, and the like. In the attribute table 422, the print data 411c does not exist. This is because each job stacked in the print queue buffer 421 refers to the print data 411c in the entry of FIG. In the present embodiment, the print queue job attribute table does not include the print data 411c, and the following description proceeds. However, the actual state of the job may exist by copying or the like. A plurality of entries 411 are searched for a job ID 411a having the same value as the value of the job ID 422a. Then, the print attribute 411b and the print data 411c of the entry 411 specified from the job ID 411a having the same value as the job ID 422a are acquired.

  Subsequently, the data structure of the hold queue data will be described with reference to FIG. Note that when a print execution instruction is given to the print data managed in the hold queue buffer 431, the print data moves to the print queue buffer 421. When a job is submitted to the hold queue, the job is entered in the hold queue buffer 431. The hold queue buffer 431 is a storage area for stored jobs managed by the job hold function program. The job to be saved received from the external device is stored in the hold queue buffer 431 together with the print settings. Since the structure of the hold queue buffer 431 is the same as that of the print queue buffer 421, detailed description thereof is omitted.

  Job attributes registered in each hold queue are managed by a hold queue job attribute table. In FIG. 4C, in the queue 1 and the queue 5, attribute tables 432 and 433 corresponding to the respective jobs stacked in the hold queue buffer 431 are registered. Actually, there are as many queues as the hold queue buffer 431. Details of the hold queue job attribute table 432 will be described below.

  The attribute table 432 includes a job ID 432a that is an ID for identifying a job, a flag 432b for identifying a mismatch determination result, and the like. In the attribute table 432, the print data 411c does not exist. This is because each job stacked in the hold queue buffer 431 refers to the print data 411c in the entry of FIG. In the present embodiment, the following description is made assuming that the print data 411c does not exist in the hold queue job attribute table, but the actual state of the job may exist by copying or the like. A plurality of entries 411 are searched for a job ID 411a having the same value as the value of the job ID 432a. Then, the print attribute 411b and the print data 411c of the entry 411 specified from the job ID 411a having the same value as the job ID 432a are acquired.

  Next, a process from when a job is input until the job is stacked in the print queue buffer 421 or the hold queue buffer 431 will be described. This process is achieved by the CPU 212 of the controller unit 205 executing a job hold function program read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  First, the user submits a job in order to perform a printing process or the like on the digital printing machine 102. The specified value of the queue relating to whether the job is specified to be stored in the print queue buffer 421 or is specified to be stored in the hold queue buffer 431 is recorded as a job attribute. After receiving a job submitted by the user, a unique ID is generated and assigned to the job. Then, one entry 411 is created for each job. The generated job ID is input to the job ID 411a in the entry 411, the print attribute of the received job is input to the print attribute 411b in the entry 411, and the received print data is input to the print data 411c in the entry 411.

  Next, the specified queue value is read, and if the specified queue value is a print queue, it is stacked in the queue of the print queue buffer 421. On the other hand, if the designated value of the queue is the hold queue, it is stacked in the queue of the hold queue buffer 431.

  When stacking in the queue of the print queue buffer 421, one attribute table 422 shown in FIG. 4B is generated for one job. The job ID is registered in the job ID 422a of the attribute table 422.

  On the other hand, when stacking in the queue of the hold queue buffer 431, one attribute table 432 shown in FIG. 4C is generated for one job. The job ID is registered in the job ID 432a of the attribute table 432.

  A job stacked in the hold queue buffer 431, that is, a job held by the job hold function program includes a sheet type designation and a paper feed stage designation as a paper feed designation.

  The sheet type designation job designates the type of sheet to be used in the print job, feeds a sheet from a paper feed stage in which the sheet type designated in the print job is set and registered, and performs print processing.

  On the other hand, the paper feed stage designation job is a job in which a specific paper feed stage is designated as a sheet feed source of a sheet used for printing. This is effective when a frequently used sheet is to be stored in a specific sheet feed tray and fed. When a paper feed stage designation job is executed, a sheet to be used in a print job is fed from the paper feed stage designated in the job, and printing is performed on the sheet.

  In the sheet type designation job, the media management unit 211 is instructed to refer to a sheet management table as shown in FIGS. 5A and 5B. An example of a sheet management table for managing information on sheets stored in each paper feed stage in the digital printing machine 102 will be described with reference to FIG. This sheet management table is stored in the HDD 209 and is referred to by the CPU 212.

  In the example shown in FIG. 5A, for each of the 10 paper feed stages included in the digital printing machine 102, information on the size 512, the media type 513, and the remaining amount 514 is provided using the paper feed stage number 511 as a key. It is managed. Note that the remaining amount of the sheet is detected by a sensor provided in each paper feed stage.

  For example, 501 in FIG. 5A indicates that the size of the sheet stored in the paper feed stage 1 is A4, the medium type is plain paper 1, and the remaining amount is 3. The numerical value indicated by the remaining amount 514 has the following meaning. 3: Full (100%), 2: Small remaining amount (25%), 1: Very small remaining amount (less than 5%), 0: No remaining amount (0%). The accuracy of detecting the remaining amount of the sheet can be made finer by increasing the accuracy of the remaining amount sensor.

  For example, full (100%) is a state in which 3000 sheets are stored in a paper feed stage that can store 3000 sheets. The low remaining amount (25%) is a state in which 750 sheets are stored in a paper feed stage that can store 3000 sheets. The remaining amount is extremely small (less than 5%) is a state in which less than 150 sheets are stored in a paper feed stage that can store 3000 sheets. “No remaining amount (0%)” means a state in which no sheets are stored in a paper feed stage capable of storing 3000 sheets, that is, 0 sheets. As described above, the remaining amount of sheets stored in each paper feed stage can be detected in three stages by the sensors provided in each paper feed stage.

  For example, when the sheet used in the sheet type designation job is “A4 color paper (red)”, the sheet management table of FIG. 5A is referred to, and “A4 color paper (red)” is set to one of the paper feed stages. It is determined whether or not the setting is registered. If it is determined that the setting is registered in the sheet feeding stage 2, the sheet feeding stage 2 is determined as a sheet feeding destination (that is, a sheet feeding stage for feeding sheets used in the job).

  On the other hand, in the job for specifying the paper feed stage, for example, when paper feed stage 1 is designated as the paper feed destination, “A4 plain paper 1” stored in the paper feed stage 1 according to the example of FIG. Paper.

  Subsequently, the flowchart shown in FIG. 6 shows details of a series of processing for receiving a print job and registering the received job in the hold queue buffer 431 or the print queue buffer 421 in the digital printer 102 according to the present embodiment. Will be described. This process is achieved by the CPU 212 of the controller unit 205 executing the PDL function program or the JDF function program read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  In step S <b> 601, the digital printing machine 102 determines whether a print job has been received via the external I / F 202. When the computer 101 inputs a print job to the digital printer 102 via the network 100, the digital printer 102 receives the print job.

  If it is determined that the print job has been received, the process proceeds to S602. On the other hand, it stays at S601 until a job is received.

  In step S602, the print settings of the job received in step S601 are analyzed, and the process advances to step S603. Note that the print setting of the job analyzed in step S602 is, for example, a setting related to whether to issue a print instruction or to perform a storage process using a job hold function.

  In S603, based on the print settings of the job analyzed in S602, the image data to be printed is expanded, and the process proceeds to S604. Note that the resulting data generated by the processing of S603 is a raster image. Alternatively, it may be intermediate data before conversion to a raster image, or data in a format that can be easily converted into a raster image, such as JPEG or JBIG.

  In step S604, it is determined whether the job received in step S601 has been instructed to be stored by the job hold function.

  If it is determined that a storage instruction has been given by the job hold function, the process proceeds to S605. In step S605, the job received in step S601 is registered in the hold queue buffer 431.

  On the other hand, if NO is determined in S604, the process proceeds to S606. In step S606, the job received in step S601 is registered in the print queue buffer 421.

  After the process of S605 or S606, a print job is received, and a series of processes for registering the received job in the hold queue buffer 431 or the print queue buffer 421 is ended.

  Next, an example of the operation screen 701 for the job hold function displayed on the operation unit 204 in the digital printing machine 102 according to the present embodiment will be described with reference to FIGS. 7A and 7B. The operation screen 701 includes a plurality of display areas, a plurality of operation buttons, and the like. Hereinafter, important points in describing the first embodiment will be described.

  The job hold function is a function that stores data to be printed in the HDD 209 of the digital printing machine 102 until a user issues a print instruction, and then executes printing according to the data received from the user. Note that with the job hold function, the digital printing machine 102 can store a plurality of print job data in the HDD 209. With this job hold function, the user can select a print job from a plurality of print jobs stored in the HDD 209 and specify the execution order, so that printing can be executed regardless of the order input to the HDD 209.

  The hold job list 702 is an area for displaying a list of print jobs stored in the hold queue buffer 431 described above in the digital printer 102. In the example of FIG. 7A, six print jobs are displayed. For example, when seven or more print jobs are stored, the user can sequentially display all stored print jobs in the hold job list 702 by touching or pressing the scroll buttons 708 and 709. In the print job displayed in the hold job list 702, a job name 704, a user name 705, and a date / time field 706 indicating the date and time when the print job is stored in the digital printing machine 102 are displayed.

  A user (that is, an operator) who operates the job hold screen identifies the user's own job by looking at the user name 705.

  Here, the user selects a print job displayed in a list in the hold job list 702 by pressing or touching it with a finger or the like.

  The example of FIG. 7B shows a display example immediately after the operator A operates the operation screen of the job hold function displayed on the operation unit 204 and selects a print job. Here, the operator A selects Job A, Job D, Job F, and Job E in this order, and four jobs are selected. The selected job is indicated by a selection mark (721, 722, 723, 724) on the left of the job name field, and a numerical value indicating the selected order is given. In addition, the last selected job is shown in reverse display (725). In the example of FIG. 7B, Job E is the last job selected in the hold job list 702.

  The print job list 703 is an area for displaying a list of print jobs stored in the print queue buffer 421 described above. In the example of FIG. 7B, a job being printed (JobX) and a job waiting to be printed (JobY) are shown. A waiting time 713 indicates an approximate waiting time until printing processing for a print job stored in the print queue buffer 421 is started.

  A print start button 711 is a button for registering the print job selected in the hold job list 702 in the print queue buffer 421 and instructing the start of print processing. When the print start button 711 is pressed while an arbitrary job is selected from the print jobs displayed in the hold job list 702, the selected print jobs are displayed in the print job list 703, and the selected order. The printing process starts. A cancel button 712 is a button for canceling the execution of the print job registered in the print queue buffer 421 by the print start button 711.

  A detail / change button 710 confirms the details of a print job selected in the hold job list 702 (that is, the print attribute 411b in the job entry 411), or changes the attribute information of a sheet used for printing. It is a button for transitioning to the screen. In the example of FIG. 7B, when the detail / change button 710 is pressed in a state where JobE is selected last, it is possible to confirm information regarding the sheet used in JobE.

  FIG. 8 shows information on sheets used in JobA, JobD, JobF, and JobE, which are selected on the hold job list 702 in FIG. 7B.

  JobA, JobD, and JobE are jobs for specifying the sheet type, and the attribute information of the sheets used in the job is configured by the combination of the size and the media type. For example, JobA indicates that two types of sheets are used, that is, a sheet whose size is A4 and whose media type is “plain paper 1” and a sheet whose size is A4 and whose media type is “double-sided coated paper 1”. ing. Similarly, JobD uses two types of sheets: a sheet having a size of LTR and a medium type “plain paper 1” and a sheet having a size of 11 × 17 and a medium type “plain paper 1”. Is shown. In addition, JobE has a sheet with a size of A4 and a media type of “plain paper 1”, a sheet with a size of A4 and a media type of “colored paper (red)”, and a size of A3 and a media type of “double-sided coat”. This indicates that three types of sheets, “paper 2”, are used.

  On the other hand, JobF is a job for specifying a paper feed stage, and includes information on a paper feed stage designated as a paper feed destination for each page of the job. For example, JobF indicates that the paper feed stage 10 is designated as the paper feed destination from the first page to the third page, and the paper feed stage 3 is designated as the paper feed destination from the fourth page to the 20th page. Show.

  The mismatch determination button 707 is a button for executing mismatch determination (mismatch determination or no remaining amount determination) processing for the print job selected in the hold job list 702. The mismatch determination button 707 may be grayed out so that it cannot be selected when there is no print job selected in the hold job list 702. In the example of FIG. 7B, mismatch determination processing is executed for each of JobA, JobD, JobF, and JobE that are in the selected state. In the first embodiment, a case where mismatch determination processing (mismatch determination or no remaining amount determination) is executed for a job stacked in the hold queue buffer 431 will be described below. Not limited to cases. A mismatch determination process may be executed for a job stacked in the print queue buffer 421.

  Therefore, in the first embodiment, mismatch determination processing is executed for a job stacked in the hold queue buffer 431, and the mismatch determination result is stored in the RAM 208 in a nonvolatile manner in association with the job. Thereafter, mismatch determination processing is newly executed for the same job, and the newly executed mismatch determination result is stored in the RAM 208 in a nonvolatile manner in association with the job. Subsequently, the mismatch determination result before newly executing the mismatch determination and the mismatch determination result after newly executing the mismatch determination are compared. The user can easily confirm the job on the operation screen even when the number of jobs to be displayed on the operation screen 701 is increased for a job for which a mismatch has been resolved or a job for which a new mismatch has occurred. The case of enabling it will be described below.

  In the digital printing press 102 according to the first embodiment, details of a series of processes for executing various processes on the operation screen 701 of the job hold function displayed on the operation unit 204 will be described with reference to the flowchart shown in FIG. explain. This process is achieved by the CPU 212 of the controller unit 205 executing a UI function program read from the ROM 207 or the HDD 209 and loaded in the RAM 208. 9, the print job is received and the received job is registered in the hold queue buffer 431 as described in FIG. Then, the hold job list 702 is displayed on the operation unit 204, and the processing of the flowchart shown in FIG. 9 is started in a state where the job has already been selected (721 to 724) as shown in FIG. 7B.

  In step S <b> 901, a state of waiting for an operation by the user is entered on the screen shown in FIG. 7B displayed on the operation unit 204. Here, it stays in this S901 until some operation is performed by the user. If the user performs any operation on the operation unit 204, the process proceeds to S902.

  In step S902, it is determined whether the mismatch determination button 707 has been pressed by the operation. If it is determined that the mismatch determination button 707 has been pressed, the process proceeds to S1000. If the print job is not selected, the process does not proceed to S1000 even if the mismatch determination button 707 is pressed. If the print job is not selected, the mismatch determination button 707 may be grayed out so that it cannot be pressed.

  In S1000, mismatch determination (non-match determination or no remaining capacity determination) processing is executed. Details of the processing of S1000 will be described later with reference to FIGS. After the process of S1000, the process proceeds to S1400.

  In S1400, the result of mismatch determination is notified. Specifically, the hold job list 702 indicates that the attribute information of the sheet used in the print job is not set and registered in any paper feed stage, or that there is no remaining sheet to be used in the print job. Display identifiable above. Details of the processing in S1400 will be described later with reference to FIG. After the process of S1400, the process proceeds to S1600.

  In S1600, the difference of the mismatch determination result is notified. Specifically, as a result of a new mismatch determination, information regarding a job that newly has a mismatch and information regarding a job that has been newly resolved are displayed in an identifiable manner on the operation screen 701 of the job hold function. . Details of the processing in S1600 will be described later with reference to FIG. After the process of S1600, the process returns to S901 to proceed with the subsequent processes.

  On the other hand, if it is determined in S902 that the mismatch determination button 707 has not been pressed, the process proceeds to S903.

  In step S903, it is determined whether the print start button 711 has been pressed by the operation. If it is determined that the print start button 711 has been pressed, the process advances to step S904. If the print job is not selected, the process may not proceed to S904 even if the print start button 711 is pressed. Alternatively, the print start button 711 may be grayed out so that it cannot be pressed.

  In step S <b> 904, a job selected from the hold job list 702 in FIG. 7B and instructed to perform printing processing is registered in the print queue buffer 421. At this time, the jobs registered in the print queue buffer 421 are displayed in the print job list 703 in FIG. After the process of S904, the process returns to S901 to proceed with the subsequent processes.

  On the other hand, if it is determined in step S903 that the print start button 711 has not been pressed, the process advances to step S905.

  In step S <b> 905, other processing according to the operation by the user is executed. As other processing, for example, by selecting a job for which mismatch determination processing has been executed and pressing a detail / change button 710, details of a print job selected in the hold job list 702 (related to sheets used in the job) Transition to a screen for calling information, etc. After the process of S905, the process returns to S901 to proceed with the subsequent processes.

  Next, details of a series of processes (S1000 in FIG. 9) relating to the execution of the mismatch determination process in the digital printing machine 102 according to the first embodiment will be described using the flowchart shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing a mismatch determination program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208. Note that the processing of S1000 is performed in response to pressing of the mismatch determination button 707. When the mismatch determination button 707 is pressed again, mismatch determination is newly performed, and the mismatch determination result is updated.

  In the first embodiment, the description will be given below regarding the case where the media mismatch determination process is executed for the print job selected by the user among the print jobs displayed in the hold job list 702. Not limited to cases. Assuming that all the print jobs stacked in the hold queue buffer 431 have been selected, the media mismatch determination process may be executed for all the print jobs stacked in the hold queue buffer 431.

  First, in S1001, it is determined whether or not the mismatch determination has been completed for all jobs to be mismatched. If it is determined that the process has not been completed, the process proceeds to S1002.

  In S1002, one job as a mismatch determination target is determined, and the process proceeds to S1003. Note that the order of jobs determined as mismatch determination targets follows, for example, the selected order indicated by the selection marks (721, 722, 723, 724) on the left side of the job name field.

  In S1003, it is determined whether the paper feed designation of the job determined as the mismatch judgment target in S1002 is a sheet type designation or a paper feed stage designation.

  As a result of the determination in S1003, if it is determined that the sheet type is specified, the process proceeds to S1100. In step S1100, mismatch determination (non-match determination / no remaining amount determination) processing for a sheet type designation job is executed. In the sheet type designation job, mismatch determination is performed by comparing the sheet attribute information used in the sheet type designation job with the sheet attribute information registered and registered in the paper feed stage. Details of the processing in S1100 will be described later with reference to FIG. After the process of S1100, the process returns to S1001 to proceed with the subsequent processes.

  On the other hand, as a result of the determination in S1003, if it is determined that the paper feed stage is specified, the process proceeds to S1200. In step S1200, a mismatch determination (no remaining amount determination) process is executed for a paper feed stage designated job. Note that in a job specified by a paper feed tray, mismatch determination is performed by determining whether there is a remaining amount of sheets stored in the paper feed tray specified by the job. Details of the processing of S1200 will be described later with reference to FIG. After the process of S1200, the process returns to S1001 to proceed with the subsequent processes.

  FIG. 11 is a flowchart for explaining the mismatch determination process (S1100 in FIG. 10) performed when the print job to be mismatched is a sheet type designation job. This process is achieved by the CPU 212 of the controller unit 205 executing a mismatch determination program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  In step S1101, the sheet type set in each paper feed stage included in the digital printing machine 102 and the remaining amount information of the sheet are acquired, and the process advances to step S1102. Note that the processing in S1101 is performed by instructing the media management unit 211 and referring to, for example, the above-described sheet management table in FIG.

  In step S1102, information on the sheet type used in the job (the job determined as the mismatch determination target in step S1002 in FIG. 10) is acquired, and the process advances to step S1103. Specifically, the print attribute 411b in the entry 411 of the job determined as the mismatch determination target is referred to, and the sheet size and media type information used in the job are acquired.

  In S1103, two types of flags (mismatch flag and no remaining amount flag) for holding mismatch determination results are set for the number of sheet types used in the job from the information on the sheet type acquired in S1102. To do. Then, the value of the mismatch flag is set to True (mismatch), the value of the remaining amount flag is initialized to True (no remaining amount), and the process proceeds to S1104.

  Note that the value of the mismatch flag and the value of the no-remaining flag are stored in the RAM 208 in a nonvolatile manner. The mismatch flag is a flag for holding a result of determining whether or not attribute information of a sheet to be used in a print job is registered in any paper feed stage (that is, a result of mismatch determination). If the attribute information of the sheet used in the print job is registered in any of the paper feed stages, the value of the mismatch flag is overwritten as False (match). On the other hand, if the attribute information of the sheet used in the print job is not registered in any paper feed stage, the value of the mismatch flag remains True (mismatch).

  On the other hand, the no remaining amount flag is a flag for holding a result of determining whether or not there is a remaining amount of a sheet to be used in a print job (that is, a result of determining that there is no remaining amount). When there is a remaining amount of sheets to be used in the print job, the value of the no remaining amount flag is overwritten as False (with remaining amount). On the other hand, when there is no remaining amount of sheets used in the print job, the value of the no remaining amount flag remains True (no remaining amount).

  In step S1104, it is determined whether or not the mismatch determination is completed for all sheet types used in the job. If it is determined that the job is completed, the mismatch determination process (S1100 in FIG. 10) performed when the job is a sheet type designation is terminated, and the process returns to S1001 in FIG. On the other hand, if NO is determined in S1104, the process proceeds to S1105.

  In step S1105, one of the sheet types used in the job is determined as a target for mismatch determination (mismatch determination or no remaining amount determination), and the process advances to step S1106.

  In step S <b> 1106, it is determined whether the mismatch determination has been completed for all the paper feed stages included in the digital printing machine 102. If it is determined that the process has been completed, the process returns to S1104 to proceed with the subsequent processes. On the other hand, if NO is determined in S1106, the process proceeds to S1107.

  In step S1107, one paper feed stage as a mismatch determination target is determined, and the process advances to step S1108.

In S1108, it is determined whether or not the sheet type determined as a mismatch determination target in S1105 is set and registered in the paper feed stage determined in S1107 (that is, mismatch determination). If it is determined that the setting is registered, the process advances to step S1109. On the other hand, if NO is determined in S1108, the process returns to S1106 to proceed with the subsequent processing.
In S1109, the value of the mismatch flag is overwritten as False (match), stored in association with the sheet type used in the job, and the process proceeds to S1110.

  In step S1110, it is determined whether or not there is a remaining amount of sheets in the paper feed stage determined in step S1107 (that is, determination of no remaining amount). If it is determined that there is a remaining amount, the process proceeds to S1111. On the other hand, if NO is determined in S1110, the process returns to S1106 to proceed with the subsequent processing.

  In S1111, the value of the no-remaining flag is overwritten as False (remaining), and is stored in association with the sheet type used in the job. After the process of S1111, the process returns to S1106 to proceed with the subsequent processes.

  Next, FIG. 12 is a flowchart for explaining the mismatch determination process (S1200 in FIG. 10) performed when the print job to be determined as a mismatch determination job is a paper feed stage designation job. This process is achieved by the CPU 212 of the controller unit 205 executing a mismatch determination program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  In step S1201, information on the paper feed stages used in the job (the job determined to be a mismatch determination target in step S1002 in FIG. 10) and information on the remaining amount of sheets in the paper feed stage included in the digital printing machine 102 are acquired. Then, the process proceeds to S1202. Specifically, the print attribute 411b in the entry 411 of the job determined as the mismatch determination target is referred to, and information on the paper feed tray used in the job is acquired. Further, by instructing the media management unit 211 and referring to, for example, the above-described sheet management table in FIG. 5A, the remaining amount information of the sheet in the paper feed stage is acquired.

  In S1202, the above-described no-remaining flag for holding mismatch determination results is set for the number of paper feed trays used in the job from the information on the paper feed trays acquired in S1201. Then, the value of the no remaining amount flag is initialized as True (no remaining amount), and the process proceeds to S1203. Note that the value of the no-remaining flag is stored in the RAM 208 in a nonvolatile manner.

  In step S1203, it is determined whether or not the mismatch determination has been completed for all paper feed stages used in the job. If it is determined that the job is completed, the mismatch determination process (S1200 in FIG. 10) performed when the job is a paper feed stage designation is terminated, and the process returns to S1001 in FIG. On the other hand, if NO is determined in S1203, the process proceeds to S1204.

  In step S1204, one of the paper feed trays used in the job is determined as a mismatch determination (no remaining amount determination) target, and the process advances to step S1205.

  In step S1205, it is determined whether or not there is a remaining amount of sheets in the paper feed stage determined as a target of mismatch determination (no remaining amount determination) in step S1204. If it is determined that there is a remaining amount, the process proceeds to S1206. On the other hand, if NO is determined in S1205, the process returns to S1203 and the subsequent processing proceeds.

  In S1206, the value of the no remaining amount flag is overwritten as False (remaining amount), and is stored in association with the paper feed stage used in the job. After the process of S1206, the process returns to S1203 to proceed with the subsequent processes.

  Then, as described above, in S1001 of FIG. 10, it is determined whether or not the mismatch determination has been completed for all the jobs to be mismatched. If it is determined that the process has been completed, a series of processes relating to the execution of the mismatch determination process is terminated, and the process proceeds to S1400 in FIG.

  The above is the details of the series of processes (S1000 in FIG. 9) related to the execution of the mismatch determination process in the digital printing machine according to the first embodiment.

  Next, a case where the mismatch determination process is executed will be described with reference to a table storing mismatch determination result flag values in FIG. It should be noted that the flag management tables (1301 to 1304) in FIG. 13 (A) are mismatches as a result of executing mismatch determination for the jobs (JobA, JobD, JobF, JobE) selected in FIG. 7 (B). An example of the value of the determination flag and the no remaining amount flag is shown. Note that the value of the mismatch determination flag for each job and the value of the no-remaining flag in the flag management table (1301 to 1304) in FIG. 13A are stored in the RAM 208 in a nonvolatile manner. Each time a mismatch determination is newly executed, the value of the flag of the mismatch determination result before the new mismatch determination is executed is not overwritten. Therefore, the flag value of the mismatch determination result after newly executing the mismatch determination is stored in the RAM 208 in a nonvolatile manner separately from the flag value of the mismatch determination result before newly executing the mismatch determination.

  For example, “11 × 17, plain paper 1” used in JobD is set and registered in the paper feed tray 9 as shown in the sheet management table of FIG. (Amount 0: 0%). Therefore, since the value of the mismatch flag of “11 × 17, plain paper 1” is False (match) and the value of the remaining amount flag is True (no remaining amount), JobD is mismatched (no remaining amount). Determined.

  Further, “A3, double-sided coated paper 2” used in JobE is not set and registered in any paper feed stage as shown in the sheet management table of FIG. Accordingly, since the value of the mismatch flag of “A3, double-sided coated paper 2” is True (mismatch), JobE is determined to be mismatch (mismatch).

  Next, details of a series of processes (S1400 in FIG. 9) for notifying the mismatch determination result in the digital printer 102 according to the first embodiment will be described with reference to the flowchart shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing a UI function program read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  In step S <b> 1401, it is determined whether there is a job that has been subjected to mismatch determination among the jobs displayed in the hold job list 702. If it is determined that there is, the process proceeds to S1402. On the other hand, if NO is determined in S1401, the series of processes (S1400) for notifying the mismatch determination result is terminated, and the process proceeds to S1600 in FIG.

  In step S <b> 1402, it is determined whether notification of mismatch determination results for all jobs for which mismatch determination has been performed for the jobs displayed in the hold job list 702 has been completed. If it is determined that the process has been completed, the series of processes (S1400) for notifying the mismatch determination result is terminated, and the process proceeds to S1600 in FIG. On the other hand, if NO is determined in S1402, the process proceeds to S1403.

  In step S1403, one job to be notified of the mismatch determination result is determined for the job displayed in the hold job list 702, and the process advances to step S1404.

  In step S <b> 1404, it is determined whether the paper feed designation of the job determined as the target of notification of the mismatch judgment result in step S <b> 1403 is a sheet type designation or a paper feed stage designation. As a result of the determination in S1404, if it is determined that the sheet type is specified, the process proceeds to S1405.

  In step S1405, the value of the mismatch flag stored in the RAM 208 is acquired for all sheet types used in the job, and the process advances to step S1406.

  In S1406, it is determined whether or not the value of the mismatch flag is False (match) for all sheet types used in the job. If it is determined that the value of the mismatch flag is True (mismatch) for at least one sheet type (that is, NO in S1406), the process proceeds to S1407.

  In step S1407, as shown in FIG. 15A, a mismatch warning mark 1501 indicating a media mismatch (mismatch) state is displayed in association with the entry of the job in the hold job list 702. In the example of FIG. 15A, a mismatch warning mark 1501 is displayed in association with a job E entry that is a sheet type designation job. The mismatch warning mark 1501 indicates that the sheet type (size and media type) used in the print job is not set and registered in any paper feed stage. After the process of S1407, the process returns to S1402 to proceed with the subsequent processes.

  On the other hand, as a result of the determination in S1406, if it is determined that the value of the mismatch flag is False for all the sheet types, the process proceeds to S1408.

  In S1408, the value of the no remaining amount flag stored in the RAM 208 is acquired for all sheet types used in the job, and the process advances to S1409.

  In step S1409, it is determined whether or not the value of the no remaining amount flag is False (with remaining amount) for all the sheet types used in the job. If it is determined that the value of the no remaining amount flag is True (no remaining amount) for at least one sheet type (that is, NO in S1409), the process proceeds to S1410.

  In S1410, as shown in FIG. 15A, a remaining amount warning mark 1502 indicating a media mismatch (no remaining amount) state is displayed in association with the job entry in the hold job list 702. . In the example of FIG. 15A, a no remaining amount warning mark 1502 is displayed in association with the entry of JobD that is a sheet type designation job. The remaining amount warning mark 1502 indicates that the remaining amount of sheets used in the print job is zero.

After the process of S1410, the process returns to S1402 to proceed with the subsequent processes.
On the other hand, as a result of the determination in S1409, if it is determined that the value of the no remaining amount flag is False (remaining amount) for all the sheet types, the process returns to S1402 and the subsequent processing proceeds. In the example of FIG. 15A, the no remaining amount warning mark 1502 is not displayed in the entry of Job A which is a sheet type designation job. That is, there is a remaining amount of sheets used in JobA.

  On the other hand, as a result of the determination in S1404, if it is determined that the paper feed designation of the job determined as the notification target of the mismatch judgment result in S1403 is a paper feed stage designation, the process advances to S1411.

  In step S1411, the value of the no remaining amount flag stored in the RAM 208 is acquired for all paper feed stages used in the job, and the process advances to step S1412.

  In S1412, it is determined whether or not the value of the no remaining amount flag is False (with remaining amount) in all the paper feed stages used in the job. If it is determined that the value of the no remaining amount flag is True (no remaining amount) in at least one paper feed stage (that is, NO in S1412), the process proceeds to S1413.

  In step S1413, as illustrated in FIG. 15A, a remaining amount warning mark 1502 indicating a media mismatch (no remaining amount) state is displayed in association with the job entry in the hold job list 702. .

  After the process of S1413, the process returns to S1402 to proceed with the subsequent processes.

  On the other hand, as a result of the determination in S1412, if it is determined that the value of the no-remaining flag is False (remaining) in all the paper feed stages, the process returns to S1402 and the subsequent processing proceeds. In the example of FIG. 15A, no remaining amount warning mark 1502 is displayed in the entry of JobF, which is a paper feed stage designation job. That is, there is a remaining amount of sheets used in JobF.

  The above is the details of the series of processes (S1100) for notifying the mismatch determination result in the digital printing machine according to the first embodiment.

  If a media mismatch condition has occurred, only the mismatch warning mark 1501 is displayed in association with the job entry. Further, although no media mismatch state has occurred, when there is no media remaining state, a case has been described in which only the no remaining space warning mark 1502 is displayed in association with the job entry. Not limited to this.

  When there are a plurality of sheet types used in a job, a media mismatch state and a medium remaining state may occur in each sheet type used in the job. In such a case, both the mismatch warning mark 1501 and the no remaining warning mark 1502 may be displayed in association with the job entry.

  In addition, when there is no remaining media status, the same type of mismatch warning mark is associated with the job entry in both the sheet type designation job and the paper feed stage designation job. Although the case of displaying 1501 has been described, the present invention is not limited to this. Displayed in association with the job entry when there is no media remaining in the sheet type job and when there is no media remaining in the paper feed job. The form of the mark may be different.

  Next, details of a series of processing (S1600 in FIG. 9) for notifying the difference of the mismatch determination result in the digital printing press 102 according to the first embodiment will be described using the flowchart shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing a UI function program read from the ROM 207 or the HDD 209 and loaded in the RAM 208. It should be noted that in response to pressing of the mismatch determination button 707 again, mismatch determination is newly performed, and the processing of the flowchart shown in FIG. 16 is started with the mismatch determination result updated.

  First, in S1601, the information of the job registered in the new resolution list and the new occurrence list is initialized, and the process proceeds to S1602.

  Note that a new resolution list indicates that a mismatch occurred before a new mismatch determination (previous determination), but after a new mismatch determination (current determination) This is a list in which jobs corresponding to newly resolved jobs are registered. On the other hand, the new occurrence list indicates that a mismatch did not occur before a new mismatch determination (previous determination), but a mismatch after a new mismatch determination (current determination). Is a list in which jobs corresponding to new occurrences are registered. Note that the information of the job registered in the new cancellation list and the information of the job registered in the new occurrence list are stored in the RAM 208.

  In step S1602, it is determined whether or not the comparison of mismatch determination results has been completed for all jobs for which mismatch determination has been newly executed. In comparison of the mismatch determination result, the flag value of the mismatch determination result before newly executing the mismatch determination and the flag value of the mismatch determination result after newly executing the mismatch determination are compared with the flag management table described above. Compare with reference to.

  If it is determined as a result of the determination in S1602 that the process has not been completed, the process proceeds to S1603.

  In step S1603, one job to be compared with the mismatch determination result is determined, and the process advances to step S1604.

  In S1604, it is determined whether the paper feed designation of the job determined as the comparison target in S1603 is a sheet type designation or a paper feed stage designation.

  If it is determined in S1604 that the sheet type is specified, the process advances to S1700. In S1700, the mismatch determination results (mismatch flag / no remaining flag) for the sheet type designation job are compared. Details of the processing in S1700 will be described later with reference to FIG. After the process of S1700, the process returns to S1602 to proceed with the subsequent processes.

  On the other hand, as a result of the determination in S1604, if it is determined that the paper feed stage is specified, the process proceeds to S1800. In step S1800, the mismatch determination result (the remaining amount flag) for the job specified by the paper feed tray is compared. Details of the processing in S1800 will be described later with reference to FIG. After the process of S1800, the process returns to S1602 to proceed with the subsequent processes.

  FIG. 17 is a flowchart for explaining the process (S1700 in FIG. 16) for comparing the mismatch determination result with the sheet type designation job.

  First, in S1701, the flag management table stored in the RAM 208 is referred to. Then, the value of the mismatch determination result flag (mismatch flag / no remaining amount flag) before newly executing the mismatch determination is acquired for the comparison target job, and the process proceeds to S1702.

  In S1702, the flag management table stored in the RAM 208 is referred to. Then, the value of the mismatch determination result flag (mismatch flag / no remaining amount flag) after newly executing the mismatch determination for the job to be compared is acquired, and the process proceeds to S1703.

  In step S <b> 1703, it is determined whether or not the value of the mismatch flag before newly executing mismatch determination is False (match) for all sheet types used in the comparison target job. If it is determined that all the sheet types are False (match), the process proceeds to S1704. On the other hand, if NO is determined in S1703, the process proceeds to S1708.

  In step S <b> 1704, it is determined whether or not the value of the no-remaining flag before the mismatch determination is newly executed is False (remaining) for all sheet types used in the comparison target job. If it is determined that all the sheet types are False (remaining), the process proceeds to S1705. On the other hand, if NO is determined in S1704, the process proceeds to S1708.

  In step S1705, it is determined whether or not the value of the mismatch flag after newly executing mismatch determination is False for all the sheet types used in the comparison target job. If it is determined that all sheet types are False (match), the process proceeds to S1706. On the other hand, if NO is determined in S1705, the process proceeds to S1707.

  In step S1706, it is determined whether or not the value of the no remaining amount flag after the mismatch determination is newly executed is False (remaining amount) for all the sheet types used in the comparison target job. If it is determined that all the sheet types are False (remaining amount), the process of comparing the mismatch determination result with respect to the job specified by the sheet type (S1700) ends, and the process returns to S1602 in FIG. Proceed with the process. On the other hand, if NO is determined in S1706, the process proceeds to S1707.

  In step S1707, information on the job to be compared (eg, job name, user name, date / time) is registered in the new occurrence list stored in the RAM 208. After the processing of S1707, the processing of comparing the mismatch determination result for the sheet type designation job (S1700) is terminated, and the processing returns to S1602 of FIG.

  In step S1708, it is determined whether or not the value of the mismatch flag after newly executing mismatch determination is False (match) for all the sheet types used in the job to be compared. If it is determined that all sheet types are false (match), the process advances to step S1709. On the other hand, if NO is determined in S1708, the process of comparing the mismatch determination result for the sheet type designation job (S1700) is terminated, and the process returns to S1602 in FIG.

  In step S1709, it is determined whether or not the value of the no remaining amount flag after newly executing the mismatch determination is False (remaining amount) for all the sheet types used in the comparison target job. If it is determined that all the sheet types are False (remaining), the process proceeds to S1710. On the other hand, if NO is determined in S1709, the process of comparing the mismatch determination result for the sheet type designation job (S1700) is terminated, and the process returns to S1602 in FIG.

  In step S1710, information on the comparison target job (eg, job name, user name, date / time) is registered in the new cancellation list stored in the RAM 208. After the process of S1710, the process of comparing the mismatch determination result for the job of specifying the sheet type (S1700) ends, and the process returns to S1602 of FIG.

  Next, FIG. 18 is a flowchart for explaining the process (S1800 in FIG. 16) for comparing the mismatch determination result with the job specified by the paper feed tray.

  First, in S1801, the flag management table stored in the RAM 208 is referred to. Then, the value of the mismatch determination result flag (no remaining amount flag) before newly executing the mismatch determination for the comparison target job is acquired, and the process proceeds to S1802.

  In S1802, the flag management table stored in the RAM 208 is referred to. Then, the value of the mismatch determination result flag (no remaining amount flag) after newly executing the mismatch determination for the comparison target job is acquired, and the process proceeds to S1803.

  In step S1803, it is determined whether or not the value of the no remaining amount flag before executing a new mismatch determination is False (remaining amount) in all the paper feed stages used in the comparison target job. If it is determined that all the paper feed stages are False (remaining), the process proceeds to S1804. On the other hand, if NO is determined in S1803, the process proceeds to S1806.

  In step S <b> 1804, it is determined whether or not the value of the no remaining amount flag after newly executing the mismatch determination is “False” (remaining amount) in all the paper feed stages used in the comparison target job. If it is determined that all of the paper feed stages are False (remaining amount), the process of comparing the mismatch judgment results with the job designated by the paper feed stage (S1800) ends, and the process returns to S1602 of FIG. Then proceed. On the other hand, if NO is determined in S1804, the process proceeds to S1805.

  In step S1805, information on the job to be compared (eg, job name, user name, date / time) is registered in the new occurrence list stored in the RAM 208. After the process of S1805, the process of comparing the mismatch determination result (S1800) with the paper feed stage designation job is terminated, and the process returns to S1602 of FIG.

  In step S1806, it is determined whether or not the value of the no remaining amount flag after the mismatch determination is newly executed is False (remaining amount) in all the paper feed stages used in the comparison target job. If it is determined that all paper feed stages are False (remaining), the process advances to S1807. On the other hand, if NO is determined in S1806, the process (S1800) of comparing the mismatch determination result with the paper feed stage designation job is terminated, and the process returns to S1602 of FIG.

  In step S1807, information on the job (for example, job name, user name, date / time) is registered in the new cancellation list stored in the RAM 208. After the process of S1807, the mismatch determination result comparison process (S1800) is terminated, and the process returns to S1602 of FIG.

  If it is determined in S1602 of FIG. 16 that the comparison of mismatch determination results has been completed for all jobs for which mismatch determination has been newly executed, the process proceeds to S1605.

  In step S1605, the new resolution list stored in the RAM 208 and job information (for example, job name, user name, date / time) registered in the new occurrence list are acquired, and the process advances to step S1606.

  In step S1606, as shown in FIG. 19, on the job hold function operation screen 701, information on the job registered in the new resolution list (1901) and information on the job registered in the new occurrence list (1902). Is displayed by a pop-up screen 1900. The pop-up screen 1900 is displayed as a screen different from the job hold function operation screen 701 (hold job list 702). Then, after the process of S1606, the process of notifying the difference of the mismatch determination result is terminated, and the process returns to S901 of FIG.

  The above is the details of the series of processes (S1600) for notifying the difference of the mismatch determination result in the digital printing machine according to the first embodiment.

  Next, an example of notifying the difference of the mismatch determination result will be described using the flag management tables in FIGS. 13A and 13B and the job hold function operation screen in FIG.

  Note that when a mismatch determination is newly executed, the sheet information managed in the sheet management table is changed from FIG. 5A to FIG. 5B. That is, the media in the paper feed tray 8 is changed and registered, and the sheets stored in the paper feed tray 8 are replaced. Further, the sheets stored in the paper feed stage 9 are replenished to change the remaining amount from 0 (0%) to the remaining amount 3 (100%), and the sheets stored in the paper feed stage 10 are used. Accordingly, the following description will be made assuming that the remaining amount 2 (25%) is changed to the remaining amount 0 (0%). It is assumed that the flag management table (1301 to 1304) in FIG. 13A is a flag management table storing a mismatch determination result before newly executing a mismatch determination. On the other hand, it is assumed that the flag management table (1311-1314) in FIG. 13B is a flag management table storing mismatch determination results after newly executing mismatch determination.

  As shown in FIG. 13B, JobA is determined as a mismatch (mismatch), and JobF is determined as a mismatch (no remaining amount). Therefore, the mismatch determination result after newly executing the mismatch determination is as shown in FIG. Notification is made on the hold job list 702 as shown in FIG. That is, the difference between the mismatch determination result before newly executing the mismatch determination and the mismatch determination result after newly executing is that the mismatch between JobD and JobE is newly resolved, and JobA and JobF This is a new mismatch. Therefore, JobD and JobE are registered in the new resolution list, and JobA and JobF are registered in the new occurrence list. As described above, as shown in FIG. 19, the pop-up screen 1900 on the job hold function operation screen 701 displays JobD and JobE information (1901) registered in the new resolution list. Also, JobA and JobF information (1902) registered in the new occurrence list is displayed.

  As described above, in the first embodiment, a job whose mismatch is newly resolved by comparing the flag values of the mismatch determination result before newly executing the mismatch determination and after newly executing the mismatch determination, and , Identified a job that has newly mismatched. Then, the user is notified of the information of the job in which the mismatch is newly resolved and the information of the job in which the mismatch has newly occurred by a pop-up screen. As a result, even when the number of jobs to be displayed on the operation screen 701 is increased for the difference between the mismatch determination result before the new mismatch determination and after the new mismatch determination, the user can operate the operation screen. It can be easily confirmed above.

  For example, it is possible for the user to identify that a job that has been determined this time that a mismatch has occurred is a job that has been previously determined that a mismatch has not occurred. Therefore, if the user has performed an operation to change the attribute information of the sheet registered and registered in the paper feed stage between the previous determination time and the current determination time, the job is caused by the operation. The user can easily recognize that a new mismatch has occurred.

  Further, for example, it is possible for the user to identify that a job that has been determined this time that no mismatch has occurred is a job that has been previously determined that a mismatch has occurred. Therefore, if the user has performed an operation to change the attribute information of the sheet registered and registered in the paper feed stage between the previous determination time and the current determination time, the job is caused by the operation. The user can easily recognize that the mismatch has been resolved.

  In the first embodiment, the case has been described in which the mismatch determination result is displayed to the user by displaying a mismatch warning mark or a no-remaining warning mark in association with the job entry for which the mismatch determination has been performed. However, it is not limited to such a case.

  For example, as a result of the mismatch determination, the user may be notified of a job for which no mismatch has occurred by using a mark having a different form from the mismatch warning mark 1501 and the no-warning warning mark 1502. In addition, as a result of the mismatch determination, it is sufficient if the user can confirm that the job is a mismatch or is a job in which there is no remaining amount before instructing the execution of the job, The user may be notified by another identifiable mark or sound or light.

  Furthermore, in the first embodiment, a case has been described in which both the information (1901) of the job in which the mismatch is newly resolved and the information (1902) of the job in which the mismatch has newly occurred are displayed on the pop-up screen 1900. It is not limited to such a case. Either pop-up screen 1900 may display either job information (1901) in which the mismatch is newly resolved or job information (1902) in which the mismatch has newly occurred. Alternatively, information on a job having no difference between the mismatch determination result before newly executing mismatch determination and the mismatch determination result after newly executing mismatch determination may be displayed on the pop-up screen 1900.

  In addition, among the jobs in which a mismatch has newly occurred, the case where a job in which a mismatch has occurred and a job in which no remaining amount has been newly generated are registered and displayed in the new occurrence list without being distinguished. However, it is not limited to such a case. By distinguishing these jobs and registering them in a new occurrence list and displaying them, the user may be notified so that a job with a new mismatch and a job with no remaining amount can be identified.

  When the mismatch determination is performed for the first time, there is no mismatch determination result before update. Therefore, if there is no mismatch determination result before update, after notifying the mismatch determination result in S1400 of FIG. 9, the process may return to S901 and proceed with the subsequent processing instead of proceeding to S1600 of FIG. 9. . Alternatively, even if there is no mismatch determination result before update, the process proceeds to S1600 in FIG. Then, by registering the information of the job in which the mismatch occurred in the first mismatch determination in the new occurrence list and registering the information of the job in which the mismatch has not occurred in the new cancellation list, the job is displayed on the pop-up screen. May be displayed.

[Second Embodiment]
In the first embodiment described above, the value of the flag of the mismatch determination result before newly executing the mismatch determination is compared with the value of the flag of the mismatch determination result after newly executing the mismatch determination. A case has been described in which a user is notified of information on a job whose mismatch has been newly resolved and information on a job whose mismatch has newly occurred on a pop-up screen.

  On the other hand, in the second embodiment, a mark indicating that the job has been newly resolved and a mark indicating that the job has newly occurred are associated with the job entry on the hold job list 702. The case of displaying and notifying the user will be described.

  On the other hand, in the second embodiment, a part of a series of processes (S1600, S1700, S1800) for notifying the difference of the mismatch determination result is different from the first embodiment. Therefore, the processes of S1600, S1700, and S1800 in the second embodiment will be described with reference to FIGS. 20 to 22 focusing on processes different from those of the first embodiment. In addition, the process common to 1st Embodiment attaches | subjects the same step number, and abbreviate | omits detailed description.

  In the process of S1600, in the second embodiment, as shown in FIG. 20, the processes of S1601, S1605, and S1606 are not performed.

  Further, in the process of S1700, in the second embodiment, as shown in FIG. 21, the processes of S1707 and S1710 described above are not performed. On the other hand, if NO is determined in S1705 described above, or if NO is determined in S1706, the process proceeds to S2101. In step S2101, a new occurrence mark 2301 as shown in FIG. 23A is associated with the entry of the job on the hold job list 702 in order to notify the user that the job is a new mismatch. indicate. After the process of S2101, the series of processes of S1700 in the second embodiment is terminated.

  If YES is determined in S1709, the process proceeds to S2102. In step S2102, a new cancellation mark 2302 as shown in FIG. 23A is associated with the entry of the job on the hold job list 702 in order to notify the user that the job has been newly resolved. indicate. After the processing of S2102, the series of processing of S1700 in the second embodiment is terminated.

  On the other hand, in the process of S1800, in the second embodiment, as shown in FIG. 22, the processes of S1805 and S1807 described above are not performed. On the other hand, if NO is determined in S1804 described above, the process proceeds to S2201. In step S2201, a new occurrence mark 2301 as shown in FIG. 23A is associated with the job entry on the hold job list 702 in order to notify the user that the job is a new mismatch. indicate. After the process of S2201, the series of processes of S1800 in the second embodiment is terminated.

  If YES is determined in S1806, the process proceeds to S2202. In step S2202, a new cancellation mark 2302 as shown in FIG. 23A is associated with the entry of the job on the hold job list 702 in order to notify the user that the job has a new mismatch. indicate. After the process of S2202, the series of processes of S1800 in the second embodiment is terminated.
