  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a schematic configuration of an image forming system 10 according to the present embodiment.

  The image forming system 10 includes a main controller 12 and a print engine unit 14.

  The main controller 12 controls the image forming operation of the print engine unit 14. The main controller 12 includes a data receiving unit 20, a control unit 22, an image data storage unit 24, and a user interface (UI) 26.

  The data receiving unit 20 receives print data from an external computer or the like, and sends the received print data to the control unit 22. Here, the print data is data in which an image of a document to be printed is described in a page description language.

  The control unit 22 includes a CPU, a ROM, and a RAM. Various programs including a program for rasterizing print data described in a page description language and converting it into bitmap image data, and a program for controlling the image forming operation of the print engine unit 14 are necessary in the ROM. Data is stored. The CPU executes a program stored in the ROM. A part of the RAM is used as a work memory. A predetermined area of the RAM is used as a buffer for temporarily storing print data.

  The recording medium for recording the program executed by the CPU is not limited to the ROM, and may be a CD-ROM, a DVD disk, a magneto-optical disk, an IC card, a hard disk, or the like, or on a telecommunication line. It may be a transmission medium such as a carrier wave and is not particularly limited. Therefore, it is possible not only to provide a program or the like according to an embodiment of the present invention, which will be described later, via a communication medium, but also to store it on a recording medium such as a CD-ROM.

  The image data storage unit 24 stores the bitmap image data converted by the control unit 22.

  The UI 26 is configured by, for example, a touch panel display in which a touch panel is superimposed on a display, and can display various information and input desired information and instructions by a user operation.

  The print engine unit 14 includes an abnormality detection unit 30, a paper transport system 32, an image formation unit 34, and an image formation control unit 36.

  As shown in FIG. 2, the image formation control unit 36 controls the image formation operation (printing operation) of the print engine unit 14 in accordance with the image data and the print control signal received from the control unit 22 of the main controller 12. Further, the image formation control unit 36 transmits an image formation end notification, an abnormality occurrence notification when an abnormality occurs during image formation, and the like to the control unit 22.

  The paper transport system 32 transports paper as an image forming medium during an image forming operation according to the control of the image forming control unit 36. Here, a general sheet is described as an example of an image forming medium that is an object on which an image is formed. However, the image forming medium is not particularly limited, and may be, for example, an OHP sheet.

  The image forming unit 34 forms an image on the paper transported by the paper transporting system 32 under the control of the image forming control unit 36. The image forming unit 34 includes an electrophotographic image forming unit including a charging device, a photoreceptor, an exposure device, a developing device, and a transfer device. Note that the image forming unit may be an ink jet type that forms an image by ejecting ink onto paper, and is not particularly limited.

  The paper on which the image is formed by the image forming unit 34 is transported and stored by the paper transport system 32 to the storage unit 38 (see FIG. 2). Further, the sheet on which the image is formed can be stored by shifting the storage position of the storage unit 38 by a storage mechanism (not shown). The storage mechanism operates according to control from the image formation control unit 36.

  The abnormality detection unit 30 includes sensors provided at a plurality of locations along the paper transport path of the paper transport system 32. The detection result of each sensor of the abnormality detection unit 30 is transmitted to the control unit 22 via the image formation control unit 36. As a result, the control unit 22 can determine which part of the paper transport path the paper has reached, and in which part the abnormality has occurred when an abnormality such as a paper jam or conveyance failure has occurred. .

  Next, the operation of the image forming system 10 of the present embodiment will be described.

  FIG. 3 is a flowchart showing the flow of image formation control processing performed by the control unit 22.

  In step 100, the control unit 22 determines whether print data has been received from the data receiving unit 20. If it is determined that the print data has been received, the control unit 22 rasterizes the received print data in step 102 to create pit map image data.

  In step 104, the control unit 22 temporarily stores the created image data in the image data storage unit 24. Note that the print data from which the image data is created is stored in a buffer secured in the RAM of the control unit 22. The print data stored in the buffer is deleted after receiving an image formation end notification from the image formation control unit 36 of the print engine unit 14 for all pages printed by the print data.

  In step 106, the control unit 22 generates a print control signal for performing printing and transmits the print control signal to the image formation control unit 36, and reads out the image data to be printed from the image data storage unit 24 and the image formation control unit 36. To form an image (print).

  In the present embodiment, the controller 22 does not generate image data for all pages in advance before the start of image formation by the print engine unit 14 when printing a series of printed matter consisting of a plurality of pages. During the image formation of the print engine unit 14, raster processing is sequentially performed to generate image data page by page, and the image data is transmitted to the image formation control unit 36, thereby printing a plurality of pages of printed matter at high speed. In this image forming system 10, whether or not the image data has been properly rasterized, that is, whether or not the transmitted image data is abnormal (proof) is determined by sending the image data to the image forming control unit 36. This is done after sending. This proof may be performed by the control unit 22 or the image formation control unit 36.

  In step 108, the control unit 22 determines whether an abnormality has occurred during image formation in the print engine unit 14.

  As described above, the print engine unit 14 is provided with the abnormality detection unit 30, and the detection results of each sensor of the abnormality detection unit 30 are transmitted to the control unit 22 via the image formation control unit 36. The controller 22 detects from the detection result that an abnormality such as a paper jam or a conveyance failure has occurred.

  Also, abnormalities that occur during image formation are not limited to paper jams or poor transport. As described above, an abnormality may be detected by proofing. When an abnormality is detected by proof during image formation, the paper on which the image data on which the abnormality is detected is printed is a purge for storing paper that has not been printed normally, different from the storage unit 38. It is transported and stored in the storage unit.

  If the control unit 22 determines in step 108 that an abnormality has occurred, the control unit 22 proceeds to step 110 and transmits a print control signal for interrupting printing to the print engine unit 14 to interrupt printing. Let

  Although not shown in the flowchart, if the abnormality that has occurred is a paper jam or a conveyance failure, the controller 22 removes the sheet with the abnormality remaining in the sheet conveyance path to the user. A message to be displayed on the UI 26. As a result, the print engine unit 14 returns from the error state. After the print engine unit 14 returns from the error state, the control unit 22 performs an abnormality occurrence process in step 112. Further, when the abnormality that has occurred is an error at the time of image data generation detected by the proof, the process proceeds to the abnormality occurrence process of step 112 as it is. The abnormality occurrence process will be described later.

  After the completion of the abnormality occurrence process or when it is determined in step 108 that no abnormality has occurred, the control unit 22 proceeds to step 114 and all printing using the print data received by the data receiving unit 20 has been completed. Determine whether or not. If it is determined that printing has not been completed, the print engine unit 14 is controlled to continue printing in step 116, and the process returns to step 102. If it is determined in step 114 that printing has been completed, the image formation control process is terminated.

  Next, the abnormality occurrence process performed in step 112 will be described.

  FIG. 4 is a flowchart showing a flow of processing at the time of occurrence of abnormality performed by the control unit 22.

  In step 200, the control unit 22 determines which sheet has an abnormality (abnormality occurrence position). For example, when the detected abnormality is an abnormality such as a paper jam or a conveyance failure, the control unit 22 detects an abnormality such as a paper jam or a conveyance failure on the conveyance path from the detection result received from the abnormality detection unit 30. The position where the error occurred is specified, and the abnormality occurrence position is determined based on the specified position. Further, when an abnormality of the image data is detected by the proof, the image data where the abnormality is detected can be immediately identified, and thus the abnormality occurrence position is determined.

  In step 202, the control unit 22 executes an image data reading process for reading image data from the image data storage unit 24.

  FIG. 5 is a flowchart showing the flow of the image data reading process.

  In step 220, the control unit 22 determines whether or not the abnormality occurrence position is the first page of a series of printed materials. When an affirmative determination is made in step 220, in step 222, the control unit 22 reads out the image data at the abnormality occurrence position and the position behind the abnormality occurrence position from the image data storage unit.

  If a negative determination is made in step 220, in step 224, the control unit 22 determines whether or not the abnormality occurrence position is the last page of a series of printed materials. If an affirmative determination is made in step 224, in step 226, the control unit 22 reads out the image data at the abnormality occurrence position and the previous position from the image data storage unit.

  When a negative determination is made in step 224, in step 228, the control unit 22 reads out the image data at the abnormality occurrence position and the positions before and after the abnormality occurrence position from the image data storage unit.

  That is, if the abnormality occurrence position is the first page, there is no previous page, and therefore it is not necessary to read image data before the abnormality occurrence position. Further, if the abnormality occurrence position is the last page, there is no subsequent page, so there is no need to read out image data behind the abnormality occurrence position. Therefore, the control unit 22 reads the image data as described above.

  Further, the number of sheets of image data read before and after the abnormality occurrence position is not particularly limited. For example, it is possible to read two sheets of image data before a sheet that is recognized as having an abnormality, and read one sheet of image data after a sheet that has been recognized as having an abnormality.

  After the image data is read out by the image data reading process, the process proceeds to step 204 in FIG. 4 to generate image data for printing the abnormality notification confirmation sheet based on the read image data. As shown in FIG. 6, the abnormality notification confirmation sheet 60 is a confirmation sheet in which an image formed on a sheet recognized as having an abnormality and an image 62 formed on the preceding and succeeding sheets are allocated within one page. It is a printed matter on which an image is formed, and it is possible to simply and efficiently perform a confirmation operation not only on a sheet that is recognized as having an abnormality but also on the preceding and succeeding sheets.

  Note that the confirmation image formed as the abnormality notification confirmation sheet 60 may be an image obtained by reducing and assigning each image so that a plurality of images are formed on one sheet. It is good also as an image which allocated each partial image. When assigning partial images, it is preferable to set in advance which part of the entire image is to be extracted.

  After generating the image data of the abnormality notification confirmation sheet 60, the control unit 22 transmits the image data and a print control signal to the image formation control unit 36 to print the abnormality notification confirmation sheet 60 on the print engine unit 14. Let

  In step 206, the control unit 22 determines whether or not the abnormality notification confirmation sheet 60 has been printed normally. For example, if an abnormality occurs during printing, it is determined that printing could not be performed normally, and the process returns to step 204 to transmit the same image data and print control signal again so as to reprint the abnormality notification confirmation sheet 60. To do. When an abnormality occurs in printing of the abnormality notification confirmation sheet 60, the abnormality notification confirmation sheet 60 in which the abnormality has occurred is simply conveyed to the purge storage unit and discharged, or only removed by the user. Further, the abnormality notification confirmation sheet 60 for this abnormality is not printed.

  On the other hand, the abnormality notification confirmation sheet 60 printed normally is transported to the storage unit by the paper transport system 32, and is stacked and stored on the printed matter that has been printed and stored so far.

  When printing is normally performed in this way, the control unit 22 determines in step 206 that printing has been performed normally, and ends the process when this abnormality occurs.

  After printing the abnormality notification confirmation sheet 60, if printing based on the print data received by the data receiving unit 20 is not completed as described above, printing based on the print data is resumed (see FIG. 3 step 114 and step 116). Therefore, the abnormality notification confirmation sheet 60 is inserted into the abnormality occurrence position of a series of printed materials. In other words, in a series of printed materials, an abnormality notification confirmation can be performed in a state in which an image formed on a sheet recognized as having an abnormality and images formed on the preceding and succeeding sheets can be compared with an abnormality occurrence position and a printing result on the front and back thereof. The sheet 60 is printed.

  After the printing with the print data is completed to the end, recovery printing is performed in which the sheet in which the abnormality has occurred is designated again and printed. The abnormality notification confirmation sheet 60 is a sheet to be printed in this recovery printing. Used to identify.

  As described above, the abnormality notification confirmation sheet 60 is stored in a state of being inserted between normal printed materials, and it is difficult to find the abnormality notification confirmation sheet 60 in the printed material after printing is finished as it is. There is also.

  Therefore, as shown in FIG. 6, the control unit 22 preliminarily controls the image forming control signal so that the abnormality notification confirmation sheet 60 is stored in a state shifted by a predetermined amount from the storage position of the normal printed matter. The data is transmitted to the unit 36. As a result, a storage mechanism (not shown) operates so that the storage position of the abnormality notification confirmation sheet 60 is shifted.

  Here, the case where the storage position of the abnormality notification confirmation sheet 60 is shifted is described as an example. However, the present invention is not limited to this. For example, a mark is attached to the peripheral edge of the abnormality notification confirmation sheet 60 or some color is used. It may be controlled so that a predetermined image is formed so that the position of the abnormality notification confirmation sheet 60 can be easily discriminated.

  There are also cases where printing is performed by designating that a blank sheet is intentionally inserted into the printed matter. In such a case, the abnormality occurrence process shown in FIG. 7 is executed instead of the abnormality occurrence process shown in FIG.

  The processing from steps 250 to 252 is the same as the processing from steps 200 to 202 in FIG.

  After reading out the image data, in step 254, the control unit 22 determines whether or not there is a blank sheet insertion designation for a sheet recognized as having an abnormality, or a sheet before and after the sheet. If it is determined in step 254 that there is no blank paper insertion designation, the control unit 22 executes the processing in steps 256 and 258 and performs the abnormality notification confirmation sheet 60 in the same manner as in steps 204 to 206 in FIG. To print.

  On the other hand, if it is determined in step 254 that there is a blank paper insertion designation, the process proceeds to step 260. Then, in step 260, based on the read image data and the blank sheet insertion position, as shown in FIG. 8, not only the image 62 of the read image data but also the image 64 in which blank characters are clearly specified is allocated, and the blank sheet is inserted. Image data for printing the abnormality notification confirmation sheet 60 whose position is clearly indicated is generated, and the abnormality notification confirmation sheet 60 is printed on the print engine unit 14. In FIG. 8, an image included in a sheet recognized as having an abnormality is C, images formed on the preceding and succeeding sheets are B and D, respectively, and a sheet for printing the image of B and an image of C 6 is a diagram illustrating a print example of the abnormality notification confirmation sheet 60 in a case where a blank sheet insertion position is designated so that a blank sheet is inserted between sheets to be printed.

  Note that the processing in step 262 is the same as that in step 206 in FIG.

  In this embodiment, the case where the abnormality notification confirmation sheet is printed with one sheet has been described as an example. However, the present invention is not limited to this, and the user can easily and efficiently identify the sheet in which the abnormality has occurred. For example, printing may be performed on a plurality of sheets as long as it is possible.

[Second Embodiment]
In the first embodiment, an example has been described in which an image formed on a sheet recognized as having an abnormality and images of sheets before and after the sheet are printed on the abnormality notification confirmation sheet 60. In the embodiment, image data indicating these images is separately stored with an identification code so that the sheet in which an abnormality has occurred can be easily reprinted (recovery printing) later, and the image and the identification code are stored. An example of printing on the abnormality notification confirmation sheet 60 will be described.

  Note that the configuration of the image forming system in the present embodiment is substantially the same as the configuration of the first embodiment, and thus description thereof is omitted.

  Further, the main routine of the image formation control process executed by the control unit 22 of the present embodiment is almost the same as that of FIG. 3 of the first embodiment. However, when an abnormality is detected in step 108, if the abnormality is an abnormality detected by the proof, the abnormality has occurred based on the print data stored in the RAM of the control unit 22. The image data formed on the sheet is regenerated and overwritten in the image data storage unit 24 and stored again. This process is also performed in a third embodiment and a fourth embodiment described later.

  Next, an abnormality occurrence process in step 112 of FIG. 3 performed in the present embodiment will be described.

  FIG. 9 is a flowchart showing a flow of processing at the time of occurrence of abnormality in the present embodiment.

  The processing from step 300 to 302 is the same as the processing from step 200 to 202 in FIG.

  After reading the image data in step 302, in step 304, the control unit 22 generates an identification code (hereinafter referred to as ID) to be given to the read image data. Here, one ID is collectively assigned to the plurality of read image data.

  In step 306, the control unit 22 associates the read image data with the ID and stores them in a predetermined area different from the area where the image data is originally stored in the image data storage unit 24.

  In step 308, the control unit 22 generates image data for printing the abnormality notification confirmation sheet 60 based on the read image data and the ID assigned to the image data. Here, for example, as shown in FIG. 10, image data in which images of all read image data and IDs assigned to the image data are printed is generated. Each image 62 of BCDE in FIG. 10 is an image obtained by reducing the image of each read image data or a partial image of the image, and a character image 66 of “error 324” indicates an ID given to these image data. It is an image.

  After generating the image data of the abnormality notification confirmation sheet 60, the control unit 22 transmits the image data and a print control signal to the image formation control unit 36 to print the abnormality notification confirmation sheet 60 on the print engine unit 14. Let In the present embodiment as well, as in the first embodiment, the abnormality notification confirmation sheet 60 is stored in the storage section 38 with a predetermined amount of shift, or a mark or the like is printed on the peripheral edge thereof. Make it distinguishable from other printed materials.

  In step 310, the control unit 22 determines whether or not the abnormality notification confirmation sheet 60 has been printed normally. If it is determined that an abnormality has occurred during printing and printing has failed, the process returns to step 308, and the same image data and print control signal are transmitted again to reprint the abnormality notification confirmation sheet 60. To do.

  On the other hand, when the control unit 22 determines in step 206 that the printing has been normally performed, the process at the time of occurrence of the abnormality is terminated.

  Note that the description of the case where blank paper insertion is designated is omitted here, but in this embodiment, when blank paper insertion is designated, control is performed as described in the first embodiment. Then, the abnormality notification confirmation sheet 60 in which the blank paper insertion position is known is printed.

  Next, recovery print control processing when recovery printing is performed after an abnormality has occurred will be described. In the present embodiment, recovery printing is performed by reading out image data using the ID printed on the abnormality notification confirmation sheet 60 as a clue.

  FIG. 11 is a flowchart showing the flow of recovery printing control processing performed by the control unit 22.

  In step 320, the control unit 22 determines whether a recovery print instruction has been input via the UI 26. If the control unit 22 determines that a recovery print instruction has been input, the recovery print screen is displayed on the UI 26 in step 322. Although not shown, the recovery print screen is provided with an ID input area for reading image data to be subjected to recovery printing by designating an ID. The user can input the ID printed on the abnormality notification confirmation sheet 60 to the ID input area.

  In step 324, the control unit 22 determines whether an ID is input. If it is determined that an ID has been input, all the image data stored in the image data storage unit 24 in association with the input ID is read in step 326, and each image data is stored based on the image data. A reduced image (or partial image) of the image represented by the image data is displayed on the UI 26. The user can select and designate an image for recovery printing from the reduced image.

  In step 328, the control unit 22 determines whether an image for recovery printing has been designated. If it is determined that an image for recovery printing has been designated, the image data of the designated image and a print control signal are transmitted to the image formation control unit 36 in step 330 to perform printing.

  In step 332, the control unit 22 determines whether or not an abnormality has occurred during the recovery printing. Even if an abnormality occurs here, the abnormality notification confirmation sheet 60 is not printed here, printing is re-executed in step 336, and the process returns to step 332.

  On the other hand, if it is determined in step 332 that no abnormality has occurred, in step 334, the control unit 22 determines whether or not recovery printing has been completed. If it is determined in step 334 that recovery printing has not been completed, printing is continued and the process returns to step 332. If it is determined in step 334 that recovery printing has been completed, the recovery printing control process is terminated. To do.

  In step 304, the control unit 22 applies one to all of the image data read in step 302 (that is, image data of an image recognized as having an abnormality and image data of images before and after the image data). Although an example of assigning an ID has been described, the present invention is not limited to this. For example, an ID may be assigned to each of read image data.

  In that case, in step 306, the ID generated for each read image data is associated with each image data and stored in a predetermined area of the image data storage unit 24.

  In step 308, the control unit 22, for example, as shown in FIG. 12, the image (reduced image or partial image) 62 of each read image data and the ID of the image data of each image corresponding to each image 62. Is printed on the abnormality notification confirmation sheet.

  Further, when IDs are individually assigned in this way, in recovery printing, recovery printing control processing is performed according to the flow shown in the flowchart of FIG.

  The processing from steps 350 to 354 is the same as the processing from steps 320 to 324 in FIG.

  In step 356, the control unit 22 reads the image data stored in the image data storage unit 24 in association with the input ID, and in step 358, the read image data and the print control signal are read out by the image formation control unit. 36 for printing.

  The processing in steps 360 to 364 is the same as the processing in steps 332 to 336 in FIG.

  The method of assigning the ID is not limited to the above. For example, in the above description, all of the image data read in step 302 (that is, the image data of the image formed on the sheet that is recognized to have an abnormality and the image data) A single ID (herein referred to as a parent ID) is assigned to the image data of the images formed on the preceding and subsequent sheets), and a child ID different from the assigned parent ID is individually assigned to each of the image data. You may make it give to.

[Third Embodiment]
In the second embodiment, the case where the ID is printed as a character image on the abnormality notification confirmation sheet 60 has been described as an example. However, in the present embodiment, the ID is converted into a two-dimensional code and printed. Will be described as an example.

  FIG. 14 is a block diagram showing a schematic configuration of the image forming system 40 according to the present embodiment. Here, the constituent elements having the same reference numerals shown in FIG. 14 and FIG. 1 mean the constituent elements having the same functions, and the description thereof will be omitted.

  The scanner unit 16 according to the present embodiment includes a reading control unit 42 and a reading unit 44.

  The reading unit 44 reads the two-dimensional code formed on the abnormality notification confirmation sheet 60 according to the control of the reading control unit 42.

  The reading control unit 42 recognizes the ID indicated by the two-dimensional code from the reading result of the reading unit 44. The recognized ID is transmitted to the control unit 22.

  The abnormality occurrence process performed by the control unit 22 of the image forming system 40 is performed in substantially the same manner as in FIG. 9 of the second embodiment. However, in step 308 of FIG. 9, the following processing is performed.

  First, the control unit 22 converts a character string indicating an ID assigned to the read image data into a two-dimensional code, and generates image data of an image of the two-dimensional code. Further, an image obtained by reducing the image of each read image data or image data of a partial image of the image is generated and synthesized with image data of a two-dimensional code. After generating the image data for printing the abnormality notification confirmation sheet in this way, the control unit 22 transmits this image data to the image formation control unit 36 together with the print control signal. Thereby, for example, an abnormality notification confirmation sheet as shown in FIG. 15 is printed.

  Next, the recovery printing control process of this embodiment will be described.

  FIG. 16 is a flowchart showing the flow of recovery printing control processing executed by the control unit 22 in this embodiment.

  In step 380, the control unit 22 determines whether or not a recovery print instruction is input via the UI 26. If the control unit 22 determines that the recovery printing instruction has been input, in step 382, a message is sent to the user to place an abnormality notification confirmation sheet on a reading table (not shown) via the UI 26. indicate. When the user places the abnormality notification confirmation sheet on the reading table according to the message, the control unit 22 uses the two-dimensional code printed on the abnormality notification confirmation sheet on the reading unit 44 via the reading control unit 42 of the scanner unit 16. To read.

  In step 384, the reading control unit 42 recognizes the ID indicated by the two-dimensional code from the reading result of the reading unit 44. The control unit 22 acquires the ID recognition result from the reading control unit 42.

  In step 386, all the image data stored in the image data storage unit 24 in association with the recognized ID is read, and a reduced image of the image represented by each image data is displayed on the UI 26 based on the image data. The user can select and designate an image for recovery printing from the reduced image.

  Thereafter, the processing from step 388 to 396 is the same as the processing from step 328 to 336 in FIG.

  In the present embodiment, the control unit 22 applies 1 to all the image data read in step 302 (that is, the image data of the image recognized as having an abnormality and the image data of the preceding and succeeding images). Although an example of assigning one ID has been described, the present invention is not limited to this. For example, an ID may be assigned to each of the read image data. In this case, the control unit 22 prints not only the two-dimensional code but also the character image of the identification code on the abnormality notification confirmation sheet 60. In the recovery printing, the ID is recognized in step 384 in FIG. Thereafter, a process for displaying the recognized ID on the UI 26 and allowing the user to select it is performed, and control is performed so that the image data associated with the selected ID is read out and reprinted.
