Description

Inspection system and display device Technical Field The present disclosure relates to inspection systems and display devices. Background Conventionally, an inspection system is known in which an image forming apparatus forms an image on a sheet and an inspection apparatus disposed downstream of the image forming apparatus inspects the sheet during execution of a job. The check performed during execution of the job is also referred to as an on-line check. In the in-line inspection, the inspection apparatus optically reads a sheet on which an image has been formed to generate read image data, and determines whether a printed image is appropriate by analyzing the read image data. In general, a defective sheet determined to be defective is discharged to a discharge destination different from that of a normal sheet. Japanese patent laid-open No. 2023-048841 discloses a system that is capable of performing offline inspection independently of job execution in addition to online inspection. In the system of japanese patent laid-open No. 2023-048841, a so-called purge and restore mode can be selected for on-line inspection. In the purge and recovery mode, when a defect is detected while a multi-page job is being performed, a defective sheet and a sheet being subsequently processed are discharged to the paper discharge tray, and an image of a page corresponding to the defective sheet and the subsequent sheet is reformed on a new sheet. Because of this reformation of the image, i.e., the recovery operation, the order of pages of the printed matter is maintained, the user does not need to do work to rearrange sheets of the printed matter, whether or not there is a defect. However, in the purge and recovery mode described in japanese patent laid-open No. 2023-048841, not only defective sheets but also some subsequent sheets are purged without preserving the order of pages, resulting in the purged subsequent sheets being wasted. This waste can be avoided if the user selects not the clear and restore mode but the clear mode, but the restore operation is not performed in the clear mode. Furthermore, the user does not always select the operation mode appropriately. Disclosure of Invention In view of the foregoing, the present disclosure is directed to an improved mechanism for assisting in selecting an appropriate mode of operation in an inspection system. According to an aspect, there is provided an inspection system comprising an image forming unit configured to form an image on a sheet, an inspection unit configured to inspect the sheet on which the image forming unit has formed the image, two or more discharge units to which the sheet inspected by the inspection unit is discharged, a setting unit configured to receive settings related to inspection, and a control unit configured to control image formation of the image forming unit and discharge of the sheet to the two or more discharge units, wherein the control unit is configured to discharge a normal sheet on which the inspection unit has not detected a defect to the first discharge unit in a first operation mode, to discharge a defective sheet on which the inspection unit has detected a defect to the second discharge unit, to cause the image forming unit to reform an image formed on the defective sheet, and to cause the image forming unit to reform a variable image on which the at least one subsequent sheet is not detected and on the basis of the first discharge unit and the variable data related to the defective sheet is not detected to the first discharge unit, to discharge a defective sheet detected by the inspection unit to the inspection unit, to discharge a defective sheet detected after the inspection unit to the defective sheet to the second discharge unit, and to the variable image formed on the basis of the variable sheet after the defective sheet is discharged to the variable sheet detected by the inspection unit to the variable sheet and the variable sheet after the defective sheet is discharged to the variable sheet to the defective sheet is discharged to the second discharge unit, and wherein the control unit is configured to cause the display device to display a message regarding the selection of the first operation mode or the second operation mode based on the setting related to the variable data check. According to another aspect there is provided a display device performing a display related to an inspection in an inspection system comprising an image forming unit configured to form an image on a sheet and an inspection unit configured to inspect the sheet on which the image forming unit has formed, wherein the inspection system is configured to, in a first mode of operation, eject a normal sheet on which the inspection unit has not detected a defect to a first ejection unit, eject a defective sheet on which the inspection unit has detected a defect to a second ejection unit, eject at least one subsequent sheet after the defective sheet to the sec
