  In the field of image forming apparatuses such as copiers, printers, and multifunction machines, image reading data obtained by reading a sheet image is used to determine whether an image is abnormal or image quality adjustment. For example, by comparing the scanned image with the image data for printing, if the printed images do not match, an abnormality is determined, or an adjustment image is printed on the inserted paper or cutting margin of the paper, and this is read. An apparatus capable of adjusting image quality is known. Also, when an adjustment image is read, the abnormality of the image can be determined based on the inability to adjust. If it is determined that the image is abnormal, it is determined that the error has occurred, and usually, output is stopped, or the discharge paper is discharged to a different discharge destination.

In the technique proposed in Patent Document 1, a sheet in which an image defect is detected is transported to a post-processing apparatus post-processing discharge destination tray, and a normal sheet following the sheet in which the defect is detected is post-processed. In order to perform this, the control is performed to eject the buffer tray temporarily stored. Thereafter, after the sheet relating to the re-output command is discharged, the sheet held on the buffer tray is discharged.
The technique proposed in Patent Document 2 includes an abnormal sheet storage unit that stores an abnormal sheet in which an abnormality is detected, and a normal sheet storage unit that temporarily stores a normal sheet in which no abnormality is detected, After the corresponding sheet is stored in the storage unit, the sheet detected as abnormal is output again, and then the normal sheet stored in the normal sheet storage unit is discharged.

The types of the networks 2 and 3 are not particularly limited, and an appropriate network such as a communication line such as a LAN (wired or wireless), WAN, or telephone line can be used. Different types may be used.
In this embodiment, an example in which one image forming apparatus, one terminal (PC), and one external apparatus are connected in the networks 2 and 3 is described. (PC), the number of external devices is not particularly limited.

Next, the basic operation of the image forming apparatus 1 will be described.
First, a procedure for accumulating image data in the apparatus main body 10 will be described. In the apparatus main body 10, a case where the scanner unit 130 reads an image and generates image data will be described. The scanner unit 130 optically reads an image from a document by the CCD 131. At this time, the operation of the CCD 131 is controlled by the scanner control unit 132 that receives a command from the control CPU 113. The reading of the document may be performed while automatically feeding the document by the casting type automatic document feeder (ADF) 14 or may be performed by placing the document on the platen glass.

  The control CPU 113 executes a program and issues a command to the scanner unit 130 based on an operation (read instruction or copy instruction) by the operation unit 140. The image read by the CCD 131 is subjected to data processing by the reading processing unit 116, and the image data subjected to the data processing is sent to the compression / expansion IC 117 via the DRAM control IC 111 and compressed by a predetermined method. The compressed data is stored in the image memory (DRAM) 120 via the DRAM control IC 111. When the image data is stored, output settings are made before or after storing the image data. The output setting can be performed by an operation input by an operator by displaying a setting screen on which operation input is possible on the operation unit 140. Further, when the output setting item is selected in the initial setting and the setting input by the operator is not made, the output setting is made by the initial setting. The output setting includes paper setting information. The image data is stored in the image memory (DRAM) 120 as image information, and the paper setting information is stored in the image memory (DRAM) 120 and the HDD 119, and is managed by the control CPU 113 as a job together with the image information.

  In addition, the image data can be input to the apparatus main body 10 via the network 2. Examples of the image data include data generated by an application program such as a terminal (PC) 4. The method for generating image data is not particularly limited. At this time, the sheet setting information set by the terminal (PC) 4 or the like is sent to the image forming apparatus 1.

  The image data is received by the image processing unit (print & scanner controller) 160 through the network 2, the LAN interface 165, and the LAN control unit 164, and the print data is transferred to the image memory 162 by the DRAM control IC 161 according to an instruction from the controller control unit 163. Be expanded. The print data in the image memory 162 is transferred to the DRAM control IC 111 via the PCI bus 112 and temporarily stored in the page memory 122. Data stored in the page memory 122 is sent to the compression / decompression IC 117 via the DRAM control IC 111 and subjected to compression processing, and stored in the HDD 119 via the compression memory 121 or the controller IC 118 via the DRAM control IC 111. The sheet setting information is stored in the image memory (DRAM) 120 and the HDD 119 and is managed by the control CPU 113 as a job together with the image information.

  When the image forming apparatus 1 outputs an image, that is, when used as a copying machine or a printer, the image data stored in the compression memory 121 or the image data stored in the HDD 119 is read out together with the printing conditions, and passed through the DRAM control IC 111. The image data is expanded by sending it to the compression / decompression IC 117, the decompressed data is sent to the writing processing unit 123, and writing is performed by the LD 152 on the photoconductor 15A charged by the charger 15C based on the printing conditions.

  In the printer unit 150, each unit is controlled by the printer control unit 151 that receives a command from the control CPU 113. In the image forming unit 15, the latent image written on the photoconductor 15 </ b> A is developed as a toner image by the developing unit, and the toner image is transferred by the transfer unit to the sheet supplied by the conveyance path and fixed by the fixing unit. In the photoreceptor 15A, after the toner image is transferred onto the paper, the residual toner is removed by a cleaning unit (not shown). The paper is fed from the main body paper feed tray 12 in the apparatus main body 10. The main body paper feed tray 12 is controlled according to the control information. At this time, the paper is fed from the paper feed tray according to the paper setting information of the job and the paper feed tray information used in the job. The paper tray information may be included in the paper setting information of the job, and the paper tray is determined according to the paper type information of the paper feeding unit from the paper type information used in the job. Also good.

The paper on which the image has been formed is conveyed to the image reading device 40 through the relay device 20 and the inserter 30. In the job for which image reading is set, the control unit 100 instructs the image reading units 41 and 42 to read the image, obtains the reading result, and determines whether the image is good or bad.
In the image forming apparatus 1, when a request for a predetermined operation is made by the external device 6, the LAN control unit 125, the LAN interface 126, the network 3, the external device control unit 60, and the LAN interface 61 are controlled by the operation of the control CPU 113. Control information is transmitted to the external device 6 via

  The paper that has passed through the image reading device 40 is conveyed to the post-processing device 50, and is discharged to the paper discharge unit 51 or the paper discharge unit 52 under the control of the control unit 100. Normally, the paper P is discharged as a normal output paper P to the paper discharge unit 51.

On the other hand, as shown in FIG. 1, if it is determined that the paper on which the image has been read is defective, the paper is determined to be spear paper PY. In the control unit 100, the paper P0 preceding the scraped paper PY is discharged to the paper discharge unit 51 as normal output paper. Further, the paper PY and the papers P1, P2, and P3, which are subsequent papers remaining in the apparatus, are discharged to the paper discharge unit 52 of the post-processing device 50 as a paper discharge paper. In the image forming apparatus of this embodiment, since the paper discharge unit 52 is provided in addition to the paper discharge unit 51 from which normal output paper is discharged, the waste discharge paper is discharged to a discharge destination separately from the paper discharge unit 51. . The sprout discharge paper corresponds to a sprout discharge medium of the present invention.
The quality of the image can be determined by comparison with the reference data as described above.

  When discharging the discharge paper, an image is read by the image reading units 41 and 42 of the image reading device 40 on the succeeding paper, and the reading result is transmitted to the control unit 100. The control unit 100 determines whether or not the image of the succeeding sheet of the paper is good or bad, and if it is determined to be defective, the control unit 100 discharges the paper to the paper discharge unit 52 as the paper. In addition, when the image is good in the quality of the image, the paper is discharged as a normal sheet to the paper discharge unit, and all the waste discharge paper is discharged to the paper discharge unit 52 as shown in FIG. In the example shown in this figure, the discharge paper includes the two papers that were first judged to be damaged, and the paper that was judged to be defective on the following paper. The paper is output.

When the image reading device 40 reads an image of the sprout discharge paper, the control unit 100 stores the image and the discharge order in the storage unit as information. As the storage unit, an image memory (DRAM) 120 or an HDD 119 is used. However, the present invention is not limited to a specific storage unit. When storing, the image and the discharge order may be stored only for the image of the paper that has been normally output, and the filed paper and the page position of the filed paper may be stored together. It may be.
When the discharge paper is completely discharged, the control unit 100 stops paper feeding, conveyance, and image formation, and displays on the operation unit 140 a prompt to set the discharge paper in the paper insertion unit 31. This display corresponds to a notification that prompts the user to install the discharged discharge medium in a transfer medium supply unit different from the transfer medium supply unit used for job output in the present invention. The notification can be performed other than the operation display unit 140, and the notification can be transmitted to the external device 6 or a terminal. The communication method is not particularly limited as the present invention.

FIG. 4 shows the above display on the operation display screen 1400 of the operation unit 140. The operation display screen 1400 is provided with a display field 1410 for performing the above-described display. The display field 1410 prompts the user to set the paper discharge paper in the paper insertion unit and to start the subsequent processing. It is displayed. On the operation display screen 1400, a start button 1411 and a cancel button 1412 are provided on the lower side of the display column 1410 so that they can be pressed. When the start button 1411 is pressed, the control unit 100 detects that a sheet is installed in the sheet insertion unit 31 and conveys the discharge paper, and forms an image again (reprinting) as necessary. I do. When the cancel button 1412 is pressed, the curl process in the present embodiment is not performed, and a new sheet is fed from the main body sheet feed tray 12 to form the image corresponding to the spur discharge sheet, and the sheet discharge unit 51 is formed. Perform recovery to discharge.
After the spear discharge sheet is inserted, job output is resumed for the subsequent sheets.

FIG. 5 shows a state in which the paper discharged from the paper discharge unit 52 is set in the paper insertion unit 31. The subsequent processing may be started by an instruction from the user such as a start button as shown in FIG. 4. Further, it is detected that a sheet is set in the sheet insertion unit 31, and accompanying this detection Subsequent spear processing may be performed automatically.
When the discharge paper is set in the paper insertion unit 31, the discharge paper is sequentially conveyed. When the paper is first transported, the control unit 100 recognizes that the paper is from the output order and the result of the judgment, and the paper discharge unit 51 from which the normal output paper is discharged. The paper is discharged to a different paper discharge unit 52. At this time, the waste paper may be discharged to the paper discharge unit 34 or the like. When discharging the paper, the control unit 100 feeds the paper corresponding to the page position of the paper from the main body paper feed tray 12 set in the job, and the image forming unit 15 re-images the paper. Form (reprint). The reprinted paper is discharged to the paper discharge unit 51 so as to match the output order. Note that the paper on which the image has been formed again can also be read by the image reading units 41 and 42 to make a sag determination.

Of the paper discharged, normally output paper is conveyed from the paper insertion unit 31 and read by the image reading units 41 and 42, and the reading result is transmitted to the control unit 100. In the control unit 100, the output order of the sheets is grasped as information, and the information on the images and the output order is stored in the storage unit. In the control unit 100, when discharging the waste paper and the remaining paper subsequent thereto, the image of the normally output paper and the output order are stored in the storage unit as information. The control unit 100 can determine whether the output order is appropriate by reading and comparing these pieces of information. That is, if the information does not match, it is determined that the output order is inappropriate. Processing when it is determined that the output order is inappropriate will be described later.
By comparing the image of the normally output paper with the image when the paper is discharged, it is possible to easily determine whether the output order is appropriate, and by using the information of the output order for this determination Can be done accurately.

FIG. 6 shows a state in which the paper set in the paper insertion unit 31 is transported and the curling process and the recovery process are completed. Only the waste paper is discharged to the paper discharge unit 52, and the paper that has been normally output and the reprinted paper that has been reprinted corresponding to the paper are discharged to the paper discharge unit 51 in an appropriate output order. Thus, the recovery process is performed without generating useless paper.
When the discharge paper is discharged from the paper insertion unit 31, the job is resumed for the paper subsequent to the job, and the paper is fed from the main body paper feed tray 12, transported, and image formation is performed.

As described above, the quality of the image in the blur determination can be determined by comparison with the reference data.

Based on the deviation determination, the control unit 100 discharges the paper PY and the paper P1, P2, and P3 remaining in the machine as the paper discharge paper. At this time, since the discharge destination is only the paper discharge unit 51, the paper is discharged separately from normal output paper. In this example, as shown in FIG. 8, the paper is distinguished from the paper that has been normally output by performing the offset paper discharge by shifting the paper and changing the paper position. In addition, the paper may be distinguished from the paper that is normally output by rotating the paper. Further, in a job for printing on one side, normal output paper and misfire paper may be distinguished by changing the front and back sides. In the present invention, the distinction method is not particularly limited. For example, when a colored insertion sheet or the like is provided, a colored insertion sheet or a sheet having a different size may be discharged and distinguished from a normal sheet.
When discharging the discharge paper, as in the first embodiment, image reading is performed by the image reading units 41 and 42 to determine the deviation. If there is an abnormality in the image of the succeeding paper, it will be treated as scraped paper.

In this example, the paper discharge unit 34 is provided between the paper insertion unit 31 and the image reading device 40, and when the paper discharge paper is conveyed from the paper insertion unit 31, the paper is upstream of the image reading device 40. The paper is discharged to the paper discharge unit 34 located at the position. In the output order corresponding to the paper, the paper is fed from the main body paper feed tray 12, and the image forming unit 15 reprints the image based on the image corresponding to the output order, and normal output paper is discharged. The paper is discharged to the paper discharge unit 51 in the proper output order. Note that the reprinted paper is judged to be defective by image reading by the image reading units 41 and 42. In the case where the paper is used, the paper discharge unit 51 can discharge the offset paper.
In addition, normal output paper in the paper discharge paper is discharged in an appropriate output order to the paper discharge unit 51 from which normal output paper is discharged.

  Out of the paper discharged, normally output paper is read by the image reading units 41 and 42 and the reading result is transmitted to the control unit 100. The control unit 100 stores the information of the image and the output order in the storage unit, and whether the output order is proper as compared with the information including the image of the normally output paper and the output order when the paper is discharged. Can be determined. If the information does not match, it is determined that the output order is inappropriate. Processing when it is determined that the output order is inappropriate will be described later.

FIG. 10 shows a state in which the paper set in the paper insertion unit 31 has been conveyed and the shearing process and the recovery process have been completed. Only the waste paper is discharged to the paper discharge unit 34, and the paper that has been output normally and the reprinted paper that has been reprinted corresponding to the paper are discharged in the proper output order to the paper discharge unit 51.

(Embodiment 3)
In the third embodiment, the image forming apparatus 1A having the paper discharge unit between the paper insertion unit and the image reading device has been described. However, the inserter may not have the paper discharge unit. An image forming apparatus 1B having this inserter 30B is shown in FIG. The post-processing device 50B has only the paper discharge unit 51 as in the post-processing device 50A of the second embodiment.

In this embodiment, when the deviation determination is performed on the printed sheet, the deviation discharge sheet is offset and discharged to the discharge unit 51 as in FIG.
After that, when the paper discharge paper is set in the paper insertion portion, the paper processing is performed as in the second embodiment. In the recovery process, as shown in FIG. 11, the offset paper is offset and discharged to the paper discharge unit 51, and normal output paper and reprinted paper are discharged to the paper discharge unit 51 in an appropriate printing order.
When the discharge paper is discharged from the paper insertion unit 31, the job is resumed for the paper subsequent to the job, and the paper is fed from the main body paper feed tray 12, transported, and image formation is performed.

(Embodiment 1-2)
Next, processing when the image forming apparatus according to the first exemplary embodiment is installed in the paper insertion unit in an incorrect order will be described.
FIG. 12 shows a state in which the sprout discharge paper is discharged to the paper discharge unit 52 of the post-processing device 50 due to the determination of the warp. Since the operation of discharging is the same as that described in the first embodiment, the description thereof is omitted. In the paper discharge unit 52, the paper is discharged in order according to the control of the control unit 100 and has the correct order.

FIG. 13 shows a state in which the user has set the paper discharge paper in the paper insertion portion 31, and the installation order is incorrect. For example, the case where it installs upside down at the time of discharge | emission is considered.
When the sheet is discharged from the sheet insertion unit 31 in this state as in the first embodiment, the control unit 100 recognizes that the first page is scraped paper, so that it is discharged as scraped paper as shown in FIG. The sheet is discharged to the unit 52, reprinted on the sheet fed from the main body sheet feeding tray 12, and discharged to the sheet discharge unit 51. At this time, since the control unit 100 recognizes that the paper being conveyed is scrap paper, it does not determine whether the output order is appropriate.

For the next sheet, the control unit 100 recognizes that it is a normal output sheet, and as in the description of the first embodiment, the image reading units 41 and 42 store the images and the output order, Compare output order information. Since the comparison results are inconsistent, the control unit 100 determines that the surgical order is incorrect and discharges the paper to a paper discharge destination different from the normal paper output destination. Paper supply, conveyance, and image formation in the image forming apparatus after discharge are stopped.
Next, a message indicating the set order confirmation and the correct set order is displayed.
In the message, the user is prompted to have the bundle A discharged to another discharge destination and the uninserted bundle B set in the paper insertion unit in the correct order according to the message.

A display example of the message is shown in FIG. On the operation display screen 1500, an incorrect order display field 1510 indicating that the order is different is provided to prompt the user to watch. Further, an appropriate order display column 1520 indicating the correct output order is displayed so that the correct order can be grasped.

Further, the conveyance may be started when it is detected that a sheet is set in the sheet insertion unit 31 without waiting for a user instruction. In the re-conveyance of the sheet from the sheet insertion unit, the scraping process and the recovery process are started in the same manner as described in the first embodiment.
When the cancel button 1531 is pressed, the conventional recovery process can be performed without performing the error process of the present embodiment.

(Embodiment 4)
Next, a description will be given of the image forming apparatus 1 </ b> C in the case where a paper sheet is detected in a state where there is a paper discharge destination different from the execution job and the inserter is on the rear side of the image reading apparatus.
In the fourth embodiment, the image forming apparatus 1 </ b> C is sequentially connected in the order of the apparatus main body 10, the relay apparatus 20, the image reading apparatus 40, the inserter 30, and the post-processing apparatus 50 from the upstream side along the sheet conveyance direction. Yes.
When the image forming apparatus 1 </ b> C determines the deviation, the deviation discharge sheet is discharged to the sheet discharge unit 52 of the post-processing apparatus 50 as shown in FIG. 16. Next, a message prompting the user to install the discharge paper in the inserter is displayed. When the user installs the discharge paper in the paper insertion unit 31 as shown in FIG. 17, the error processing is started as in the first embodiment. The

In the shearing process, as shown in FIG. 18, the paper that has been judged to be skewed is discharged to the paper discharge unit 52 as determined, and images in the output order corresponding to the paper are from the main body paper feed tray 12. New paper is supplied, reprinted, and discharged to the paper discharge unit 51 in the proper output order. Normal output paper during the paper discharge is discharged to the paper discharge unit 51 in an appropriate output order.
When the paper on the inserter runs out, the job printing for the next page is resumed.
In this embodiment, the inserter 30 is located on the rear side of the image reading device, and the paper discharged from the inserter does not pass through the image reading device, so that it cannot be detected. There is no control.

  In each of the above-described embodiments, the explanation has been given on the assumption that the discharge paper is installed in the inserter to perform the correction process. However, the discharge processing is performed by storing the discharge paper in a paper supply tray different from the paper supply tray used by the job. It is also possible for the present invention. At this time, when passing through the image forming unit 15 or the like, it is desirable that normal output paper passes through the apparatus main body without being stained. In this embodiment, regardless of the installation position of the image reading apparatus, it is possible to determine whether the order is proper by conveying the spear discharge sheets.

Next, the procedure of the deviation determination and the deviation process of the present invention will be described with reference to FIGS. 19 and 20. The following procedure is executed under the control of the control unit or the management control unit.
Printing is performed on a sheet by starting output of the job (starting printing) (step s1). Next, it is determined whether a deviation has been detected (step s2). If no deviation has been detected (No in step s2), it is determined whether there is still printing paper (step s11). If the printing is finished (No in step s11) and there is still printing paper (Yes in step s11), the process returns to step s1 to continue the process.

If a gap is detected on the printed paper (step s2, Yes), it is determined whether there is a paper discharge destination different from the execution job (step s3). If there is a discharge destination different from the execution job (step s3, Yes), the discharge paper and its subsequent paper are discharged to a discharge destination different from the execution job, and the detection of the deviation is also performed for the subsequent paper. (Step s4). If there is no paper discharge destination different from the execution job (step s3, No), the offset paper is applied to the paper and its subsequent paper, and the paper is discharged to the same paper discharge destination as the execution job. Detection is performed (step s5).
After steps s4 and s5, the page position of the paper, the order of the normal paper, and the data of the normal paper image are stored in the storage unit (step s6). After completing the paper discharge and the succeeding paper, printing is stopped (step s7).

  Next, a message that prompts the user to set the paper after the splinter paper on the inserter is displayed (step s8). When the paper after the paper is set in the inserter, printing is resumed (step s9), and the recovery operation is performed (step s10). Details of the recovery operation will be described later. After the recovery operation, it is determined whether there is still printing paper (step s10). If there is no printing paper, the process ends (step s11, No). If there is still printing paper (step s11, Yes), step s1. Return to, print on paper, and repeat the following steps.

Next, the procedure of the recovery operation in step s10 will be described based on the flowchart of FIG. The following procedure is executed under the control of the control unit or the management control unit.
It is determined whether the paper inserted from the inserter with the start of the recovery process is scraped paper (step s20). If the paper is scraped (step s20, Yes), it is determined whether there is a paper discharge destination different from the execution job (step s21). If there is another discharge destination for the execution job (step s21, Yes), the discharge paper is discharged to a different discharge destination from the execution job (step s22), and the discharge paper page is reprinted and discharged. (Step s24). If there is no paper discharge destination different from the execution job (step s21, No), the offset paper is applied to the discharge paper and discharged to the same paper discharge destination as the execution job (step s23), and the printing paper page is reprinted. The paper is then discharged (step s24). After step s24, it is determined whether there is still a sheet to be inserted from the inserter (step s32). If there is no sheet to be inserted from the inserter (step s32, No), the recovery process is terminated and the process proceeds to step s11. If there is a sheet to be inserted from the inserter (step s32, Yes), the procedure returns to step s20 to repeat the procedure for determining whether the sheet to be inserted from the inserter is a blank sheet.

In step s20, if the paper to be inserted from the inserter is not spear paper (No in step s20), normal paper in the spout paper is inserted from the inserter into the transport path (step s25), and a post-processing machine having a spear detection function It is determined whether the (image reading apparatus) is in the subsequent stage of the inserter (step s26). If there is no post-processing device (image reading device) having a deviation detecting function after the inserter (No in step s26), the process proceeds to step s32 to determine whether there is still a sheet to be inserted from the inserter.
If the post-processing device (image reading device) having a sag detection function is in the latter stage of the inserter (step s26, Yes), the image of the inserted paper is read (step s27), and the stored normal paper image and output position are inserted. It is determined whether the image of the printed paper matches the output position (step s28). If both match (step s28, Yes), the process proceeds to step s32.

  If the two do not match (No in step s28), printing is stopped (step s29), a message prompting to confirm the order of the sheets set in the inserter, and a message clearly indicating the correct setting order in the inserter Is displayed (step s30). When the paper is reset in the inserter, printing is started (step s31), and the procedure returns to step s20 to repeat the procedure for determining whether the paper to be inserted from the inserter is scraped paper.
