  As described above, the printer 120 includes the image forming apparatus 121, the waste paper detection apparatus 122, the post-processing apparatus 123, and the paper feeding apparatus 124, and is configured by connecting these apparatuses.

  Under the control of the CPU 1211, the image forming apparatus 121 performs printing by transferring and fixing a toner image to a sheet conveyed through the conveyance path 1218 d by a transfer unit 1218 b and a fixing unit 1218 c that are components of the engine 1218. .

  The registration roller 1218a corrects the bend, inclination, and deviation of the paper transported through the transport path 1218d. By correcting the bend, inclination, and deviation of the paper in the conveyance path 1218d, the accuracy of the position of the image printed on the paper is improved, and the occurrence of sag paper due to the misalignment of the image is suppressed.

  The transfer unit 1218b includes, for example, a photosensitive drum. The surface of the photosensitive drum is uniformly charged by a charging unit (not shown), and a latent image is formed by irradiating laser light according to an image information signal by an optical writing unit (not shown). A toner image is formed by developing with a developing device (not shown). The toner image is transferred onto the sheet by the photosensitive drum in the conveyance path 1218e.

  In the transfer unit 1218b of the image forming apparatus 121 capable of color printing, a toner image of each color (Y (Yellow), M (Magenta), C (Cyan), K (Black)) is transferred to a plurality of photosensitive drums. Each is formed and then transferred onto an intermediate transfer belt (not shown) to form a color toner image on which the toner layers of each color are superimposed on the intermediate transfer belt. Then, the color toner image is transferred onto the sheet by the intermediate transfer belt in the conveyance path 1218e.

  The fixing unit 1218c includes a heating roller and a pressure roller, and forms a substantially arc-shaped nip region formed when the heating roller is pressed by the pressure roller. The paper on which the toner image has been transferred passes through the nip region of the fixing unit 118c so that the toner image is placed on the side of the paper, whereby the toner in the toner image is pressurized and heated, and the toner image is fixed on the paper. The

  The sheet paper detection device 122 includes an inline sensor 1221 and a control unit 1223 provided along the conveyance path 1222, and detects the sheet paper for the sheet conveyed on the conveyance path 1222. The splinter paper detection device 122 detects, as a splinter paper, a paper that does not satisfy the level of quality permitted as a product due to, for example, wrinkles, folds, tilts, stains, image misregistration, or color misregistration.

  The control unit 1223 detects the waste paper based on the color optically detected by the inline sensor 1221. For example, the control unit 1223 identifies the leading edge of the paper based on the color information detected by the inline sensor 1221, and removes the paper whose inclination of the leading edge of the paper exceeds a predetermined threshold due to the problem of the inclination of the paper. Can be detected as In addition, the control unit 1223 detects, for example, a sheet whose color deviation, which is a color difference from the target, exceeds a predetermined threshold based on the image data and the color of the image printed on the sheet detected by the inline sensor 1221. It can be detected as scraped paper due to color misregistration. In addition, the control unit 1223 compares the position of the image printed on the paper detected by the inline sensor 1221 with the position of the image based on the print settings, for example, so that the image displacement exceeds a predetermined threshold. The detected paper can be detected as a waste paper due to a problem of image misalignment.

  The post-processing device 123 discharges paper other than the paper detected as the paper by the paper detection device 122 to the main paper discharge tray 1236a. For all the pages where the splinter paper is not detected, the binding unit 1235 performs the post binding process and is discharged as a product to the main paper discharge tray 1236a. On the other hand, for a part of the page where the paper is detected, the paper other than the paper detected as the paper is discharged to the paper discharge tray 1236a without the post-processing by the binding unit 1235. Is done.

  The post-processing device 123 discharges the paper detected as the paper by the paper detection device 122 to the sub paper discharge tray 1236b that is the second tray without performing post-processing.

  In accordance with the reprint job transmitted from the server 110 to the printer 120, the post-processing device 123 collates a sheet other than a sheet detected as a scraped paper and a reprinted sheet among the sections where the scraped paper is detected. Do. The paper other than the paper detected as the paper of the detected paper is set in the paper inserter 1237 by the user. When the post-processing device 123 transports the paper from the paper inserter 1237 to the binding unit 1235 in the page order, the post-processing device 123 inserts the reprinted paper at the page position of the page of the reprinted paper. As a result, a sheet other than the sheet detected as the scraped sheet and the reprinted sheet are collated in the page order.

  FIG. 7 is an explanatory diagram showing a concept of collation between a sheet other than the sheet detected as the scraped sheet and the reprinted sheet.

  FIG. 7A shows that according to the print job, 10 copies of the printed matter having 10 pages are printed, and the paper is detected on the third page of the third copy and the eighth page of the eighth copy. . In the figure, the numbers in parentheses indicate the order of printing for each copy of the printed matter, and the detected paper is thickly shaded.

  In FIG. 7B, the third and eighth copies in which the offset paper is detected on pages 3 and 8 respectively, and the paper on which the images of the third and eighth pages in which the offset paper is detected are reprinted are shown. It is shown. The reprinted paper is thinly shaded.

  In FIG. 7C, the 3rd page and the 8th page are detected, and the 3rd page and the 8th page are detected. The combined state is shown.

  FIG. 8 is a flowchart of the reprinting process for the generated paper. This flowchart can be executed by the CPU 111 of the server 110 in accordance with a program stored in the storage unit 112 of the server 110.

  The CPU 111 receives the occurrence of the waste paper from the first printer 120 in which the waste paper is detected, thereby recognizing the occurrence of the waste paper and determining the content of the failure of the waste paper and the occurrence frequency of the waste paper. The CPU 111 can recognize the print job and the page in which the waste paper is detected based on the received situation of the waste paper.

  By receiving the printer status from each of the printers 120, 130, and 140, the CPU 111 can recognize the printer performance such as whether color printing is possible and the paper setting status of the printer, for example.

  If the CPU 111 determines that the content of the defect paper is a paper crease, fold, or tilt (S101: YES), the occurrence of the waste paper is continuous because the frequency of occurrence of the waste paper is high. (S103: NO), a reprint job is generated, transmitted to the first printer 120, and reprinted on the first printer 120 (S111). If the content of the problem with the splinter paper is a paper curl, crease, or tilt, it is considered that the spear paper has occurred accidentally. Therefore, it is easiest to reprint the first printer 120 that has generated scrap paper without changing the printer, and it is desirable from the viewpoint of suppressing the increase in man-hours. In addition, the consistency of the print quality between the reprinted paper and the other paper is maintained, which is desirable from the viewpoint of ensuring the print quality.

  On the other hand, when the CPU 111 determines that the content of the problem of the scraped paper is paper curl, fold, or tilt (S101: YES), the CPU 111 determines that the generation of the scraped paper is continuous. (S103: YES), basically, a printer other than the first printer 120 is reprinted. In other words, if the page to be reprinted is determined to be monochrome based on the print settings of the print job (S104: YES), the paper specified in the print settings for the page is set in the second printer 130. If this is the case (S105: YES), a reprint job is generated and transmitted to the second printer 130 capable of monochrome printing only, and reprinting is performed (S106). On the other hand, if it is determined that the page to be reprinted is color (S104: NO), if the paper designated in the print settings for the page is set in the third printer 140 (S108: YES), reprinting is performed. A job is generated and transmitted to the third printer 140 capable of color printing to perform reprinting (S110). If the generation of scraping paper is continuous in the first printer 120, it is considered that maintenance of the first printer 120 is necessary. Therefore, reprinting can be performed without performing maintenance for removing the cause of the occurrence of the waste paper by causing the reprintable printer other than the first printer 120 that has generated the waste paper to perform reprinting. Therefore, it is desirable from the viewpoint of early completion of a reprint job and reduction of man-hours required for maintenance. If the page to be reprinted is monochrome, reprinting with a printer capable of only monochrome printing can complete the reprint job at an earlier stage and prevent an increase in cost.

  If it is determined that the page to be reprinted is monochrome (S104: YES), and the paper designated in the print settings for the page is not set in the second printer 130 (S105: NO), the first printer Maintenance of 120 is performed, and the first printer 120 is reprinted according to the reprint job (S109, S111). Similarly, when it is determined that the page to be reprinted is color (S104: NO), and the paper designated in the print setting of the page is not set in the third printer 140 (S108: YES), Maintenance of the first printer 120 is performed, and the first printer 120 is reprinted according to the reprint job (S109, S111). If there is a man-hour or delay for maintenance or paper replacement regardless of which printer is used for reprinting, ensuring print quality consistency between the reprinted paper and other papers From this point of view, it is desirable to maintain and reprint the printer that generated the waste paper.

  When the CPU 111 determines that the content of the defect paper is not a paper crease, fold, or tilt (S101: NO), and determines that the problem is a color-related problem such as image color misregistration (S102: YES), taking into account the number of prints from the most recently performed maintenance to the present time in each printer (hereinafter referred to as “the number of prints after adjustment”), the first printer 120 or the third printer 140 follows the reprint job. Reprint.

  That is, when the adjusted number of printed sheets of the third printer 140 is equal to or larger than the adjusted number of printed sheets of the first printer 120, the first printer 120 is maintained and reprinted by the first printer 120 according to the reprint job ( S109, S111). The occurrence of scraping paper due to color-related defects is considered to be caused by color misregistration or the like with the lapse of the operation time of the apparatus. Therefore, when the number of printed sheets after adjustment is smaller in the first printer 120 than in the third printer 140 or the same Even if reprinting is performed by the third printer 140, there is a possibility that a waste paper due to a color-related defect will eventually occur. Therefore, in this case, it is most convenient to perform the reprinting by maintaining the first printer that has generated the waste paper without changing the printer, and it is desirable from the viewpoint of suppressing an increase in man-hours. In addition, the consistency of the print quality between the reprinted paper and the other paper is maintained, which is desirable from the viewpoint of ensuring the print quality.

  On the other hand, when the adjusted print number of the third printer 140 is less than the adjusted print number of the first printer 120, the paper designated in the print setting of the page to be reprinted is set in the third printer 140. (S108: YES), the third printer 140 is caused to reprint according to the reprint job (S110). If the first printer 120 has a scraped paper due to a color-related defect, it is considered that maintenance of the first printer 120 is necessary. Therefore, by causing the third printer 140 capable of reprinting colors other than the first printer 120 that has generated scraping paper to perform reprinting, reprinting can be performed without performing maintenance to eliminate the cause of the scraping paper generation. Therefore, it is desirable from the viewpoint of early completion of the reprint job and reduction of man-hours required for maintenance. When it is known that color misregistration has occurred in the third printer 140, the first printer 120 is maintained, and the first printer 120 is reprinted according to the reprint job.

  When the number of printed pages after adjustment of the third printer 140 is less than the number of printed pages after adjustment of the first printer 120, and the paper designated in the print setting of the page to be reprinted is not set in the third printer 140 (S108: NO), the first printer 120 is maintained and reprinted according to the reprint job (S109, S111). If there is a man-hour or delay for maintenance or paper replacement regardless of which printer is used for reprinting, ensuring print quality consistency between the reprinted paper and other papers From this point of view, it is desirable to maintain and reprint the printer that generated the waste paper.

  In this way, by taking into consideration the points of ensuring print quality, suppressing man-hours increase, and early completion of reprint jobs, let the most appropriate printer reprint the page where the waste paper has occurred, When this occurs, more efficient and high-quality reprinting can be performed.

  If the image forming system 100 further includes a printer capable of color printing and a printer capable of only monochrome printing in addition to the second printer 130 and the third printer 140, the printing speed of the printer, the number of prints after adjustment, The printer to be reprinted may be determined based on at least one of the remaining paper amounts set in the apparatus.

  As described above, the image forming system, the image forming system program, and the computer-readable recording medium that records the image forming system program according to the embodiment of the present invention have been described. However, the present embodiment has the following effects.

  In an image forming system including a plurality of printers, a selected printer is caused to reprint a page printed on a paper detected as a paper and collate with a paper other than the paper detected as a paper. As a result, regardless of the cause of the occurrence of the waste paper, the processing when the waste paper is generated can be performed more efficiently.

  The paper detected as the paper is discharged to a different tray from the paper other than the paper detected as the paper, and an instruction to collate the paper other than the paper detected as the paper with the reprinted paper is given. To do. As a result, it is possible to more easily identify paper other than the paper detected as the paper as the paper detected as the paper, and collate with the reprinted paper.

  A printer to be reprinted is selected on the basis of at least one of the occurrence status of the waste paper, the print setting of the print job, and the status of the image forming apparatus. As a result, more efficient and high-quality reprinting can be performed when scraped paper is generated.

  A printer to be reprinted is selected on the basis of at least one of the content of the problem of the waste paper, the occurrence frequency of the waste paper, the print setting for selecting color or monochrome, the performance of the printer, and the paper setting status in the printer. As a result, more efficient and high-quality reprinting can be performed when scraped paper is generated.

  Instructs the selected printer to reprint the page on the paper, and the paper inserter provided in the selected printer to collate the paper other than the paper detected as a waste paper with the reprinted paper. Generate a reprint job. Then, the reprint job is transmitted to the selected printer, thereby instructing reprinting and collation between the paper other than the paper detected as the waste paper and the reprinted paper. As a result, it is possible to reduce the burden on the user when manual paper is generated.

  The image forming system, the image forming system program, and the computer-readable recording medium on which the image forming system program is recorded are not limited to the above-described embodiments.

  For example, in the above-described embodiment, when a reprint job is transmitted to the selected printer, the printer reprints the page printed on the waste paper and reprints the paper other than the waste paper according to the reprint job. Collation with printed paper is made. However, regardless of the reprint job, reprinting and collation may be performed by transmitting commands corresponding to the commands described in the reprint job individually and step by step to the selected printer. .

  Further, in the above-described embodiment, the example of whether or not color printing is possible has been described as an example of the printer performance considered when selecting a printer to be reprinted. However, for example, the presence or absence of a paper inserter necessary for paper collation or the resolution of the image forming apparatus may be further considered as the performance of the printer.

  In the above-described embodiment, flat stitching has been described as an example of post-processing. However, the post-processing may be, for example, stapling processing or punching processing.

  In addition, some or all of the functions executed by the program in the above-described embodiment may be replaced with hardware such as a semiconductor circuit.
