Inspection system and display apparatus

An inspection system, comprising:

• an image-forming unit configured to form an image on a sheet;
• an inspection unit configured to inspect a sheet on which an image has been formed by the image-forming unit;
• two or more discharge units to which sheets inspected by the inspection unit are discharged;
• a setting unit configured to receive a setting related to the inspection;
• and
• a control unit configured to control image formation by the image-forming unit and discharge of sheets to the two or more discharge units,
• wherein the control unit is configured to:
• in a first operation mode,
• discharge a normal sheet with which no defect has been detected by the inspection unit to a first discharge unit;
• discharge a defective sheet with which a defect has been detected by the inspection unit to a second discharge unit;
• discharge at least one subsequent sheet that is subsequent to the defective sheet to the second discharge unit;
• cause the image-forming unit to re-form an image that has been formed on the defective sheet;
• and
• cause the image-forming unit to re-form an image that has been formed on the at least one subsequent sheet, and
• in a second operation mode,
• discharge a normal sheet with which no defect has been detected by the inspection unit to the first discharge unit;
• discharge a defective sheet with which a defect has been detected by the inspection unit to the second discharge unit;
• discharge at least one subsequent sheet that is subsequent to the defective sheet and with which no defect has been detected by the inspection unit to the first discharge unit;
• and
• cause the image-forming unit to re-form an image that has been formed on the defective sheet,
• wherein the setting related to the inspection includes a setting related to variable data inspection, the variable data inspection being based on matching with variable data that is different per page, and
• wherein the control unit is configured to cause a display apparatus to display a message regarding selection of the first operation mode or the second operation mode on the basis of the setting related to the variable data inspection.
