Abstract
An image forming system includes an image forming unit, an inspection unit, a conveyance unit configured to convey a sheet to the inspection unit, a controller configured to execute a first inspection mode in which a sheet having an image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and is inspected, and a setting unit configured to set a recovery process. The setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.
Claims13
An image forming system comprising:
- an image forming unit configured to form an image on a sheet;
- an inspection unit configured to inspect an image on a sheet;
- a conveyance unit configured to convey a sheet to the inspection unit;
- a controller configured to execute a first inspection mode in which an image is formed on a sheet by the image forming unit and the sheet having the image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected by the inspection unit, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and inspected by the inspection unit;
- and
- a setting unit configured to set a recovery process such that in a case where the inspection unit determines that the sheet conveyed by the conveyance unit is an abnormal sheet having abnormality in the image, an image corresponding to the image formed on the abnormal sheet is formed according to image data used to form the image on the abnormal sheet by the image forming unit on a sheet different from the abnormal sheet,
- wherein the setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.

- an image forming unit configured to form an image on a sheet;
- an inspection unit configured to inspect an image on a sheet;
- a conveyance unit configured to convey a sheet to the inspection unit;
- a controller configured to execute a first inspection mode in which an image is formed on a sheet by the image forming unit and the sheet having the image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected by the inspection unit, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and inspected by the inspection unit;
- and
- a setting unit configured to set a recovery process such that in a case where the inspection unit determines that the sheet conveyed by the conveyance unit is an abnormal sheet having abnormality in the image, an image corresponding to the image formed on the abnormal sheet is formed according to image data used to form the image on the abnormal sheet by the image forming unit on a sheet different from the abnormal sheet,
- wherein in a case where a job is started in a state in which the recovery process is set by the setting unit so as to be performed in the second inspection mode, the controller cancels the job.

An image forming system comprising:
- an image forming unit configured to form an image on a sheet;
- an inspection unit configured to inspect an image on a sheet;
- a conveyance unit configured to convey a sheet to the inspection unit;
- a controller configured to execute a first inspection mode in which an image is formed on a sheet by the image forming unit and the sheet having the image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected by the inspection unit, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and inspected by the inspection unit;
- and
- a setting unit configured to set a predetermined process in which in a case where a sheet conveyed by the conveyance unit is determined, by the inspection unit, to be an abnormal sheet having abnormality in the image, the abnormal sheet is discharged to a discharge portion different from a discharge portion to which a normal sheet is discharged, and an image corresponding to the image formed on the abnormal sheet is printed according to image data used to form the image on the abnormal sheet on a sheet different from the abnormal sheet,
- wherein the setting unit permits setting of the predetermined process in the first inspection mode and prohibits setting of the predetermined process in the second inspection mode.
4 more elements
A method of controlling an image forming system including an image forming unit configured to form an image on a sheet, an inspection unit configured to inspect an image on a sheet, and a conveyance unit configured to convey a sheet to the inspection unit, the method comprising:
- selecting one of a first inspection mode in which an image is formed on a sheet by the image forming unit and the sheet having the image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected by the inspection unit, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and inspected by the inspection unit;
- and
- setting a recovery process such that in a case where the inspection unit determines that the sheet conveyed by the conveyance unit is an abnormal sheet having abnormality in the image, an image corresponding to the image formed on the abnormal sheet is formed according to image data used to form the image on the abnormal sheet by the image forming unit on a sheet different from the abnormal sheet,
- wherein in the setting, the setting of the recovery process in the first inspection mode is permitted but the setting of the recovery process in the second inspection mode is prohibited.
