An image forming system includes: an image forming apparatus that forms a first image according to a job on a plurality of first sheets and inserts a second sheet between the plurality of first sheets; a cutting processor that sequentially performs cutting processing on the plurality of first sheets and the second sheet that are conveyed from the image forming apparatus; and a sheet discharging tray on which an output object obtained by the cutting processing on each of the plurality of first sheets and a slip sheet obtained by the cutting processing on the second sheet are stacked, wherein the cutting processor performs the cutting processing on each of the plurality of first sheets in accordance with a first cutting condition, and performs the cutting processing on the second sheet in accordance with a second cutting condition different from the first cutting condition.

An image forming system includes a conveyance processing portion, a setting processing portion, an insertion processing portion, and an operation control portion. The conveyance processing portion executes a conveyance process to convey a plurality of sheets placed on a sheet placing portion, sequentially to a sheet stack portion. When the insertion timing to insert the insertion sheet comes during an execution of the conveyance process, the insertion processing portion executes an insertion process to convey a sheet from the sheet supply source of the insertion sheet to the sheet stack portion. The operation control portion is configured to control operations of an image forming apparatus during execution of a sheet bundle output process based on the sheet type of the insertion sheet conveyed in the insertion process that is included in the sheet bundle output process, the sheet bundle output process including the conveyance process and the insertion process.

An image processing system includes an image forming device, a sensor, processing circuitry, and an ejection device. The image forming device forms an image based on print information, on a first conveyance medium. The sensor acquires information about the image formed on the first conveyance medium. The processing circuitry causes a second conveyance medium to be ejected in a case where the image formed on the first conveyance medium is a defective image, based on the acquired information. The ejection device stacks the first conveyance medium and the second conveyance medium. The processing circuitry controls display of identification information that distinguishes and associates each one of a plurality of first conveyance media having defective images, with a corresponding one of a plurality of second conveyance media.

Provided is an image formation system including an image formation device and a post-processing device configured to convey a paper sheet on which an image has been formed at the image formation device or carry out post-processing thereon, including: a paper ejection tray on which the discharged paper sheet is placed; a jam detector configured to detect a jam of the paper sheet conveyed in a paper conveyance passage; a partition paper sheet inserter configured to insert a partition paper sheet on the paper ejection tray; and a control unit, wherein the control unit controls the partition paper sheet inserter such that, after the jam is detected and paper sheets to be removed, at least including a responsible paper sheet, are removed, the partition paper sheet is inserted on the paper ejection tray before the paper sheet remaining in the paper conveyance passage is discharged to the paper ejection tray.

A control apparatus comprises: a grouping unit that divides a plurality of sheets each associated with image data included in a processing target job into groups each having a predetermined size; and a control unit that controls feeding of a sheet from a feeding unit onto a conveyance path and refeeding of a sheet which has been conveyed on the conveyance path onto the conveyance path, wherein the predetermined size is not less than a maximum sheet size used in the processing target job, a plurality of groups can be conveyed on the conveyance path, and the control unit controls feeding and refeeding for each group grouped in the grouping unit.

An image forming system includes a first feeding portion configured to feed a recording sheet, an image forming portion, a sheet conveyance path, a second feeding portion configured to feed an inserting sheet from any of a plurality of supporting portions including a first supporting portion and a second supporting portion, a detection portion, and a controller. The controller is configured to execute, during execution of a process of feeding a first inserting sheet from the first supporting portion to the sheet conveyance path, a movement processing of moving a second inserting sheet supported on the second supporting portion to a position where a trailing edge of the second inserting sheet is placed downstream in a sheet conveyance direction of a detection position of the detection portion and thereafter stopping the second inserting sheet.

An image forming system comprises first and second sheet feeding trays and first and second inserter trays. If sheets that are loaded in the first inserter tray run out during execution of a job in which a sheet feeding source of an insertion sheet is set to the first inserter tray, the system switches from the first inserter tray to the second inserter tray and continues execution of the job. If sheets that are loaded in the second sheet feeding tray run out during execution of a job in which a sheet feeding source is set to the second sheet feeding tray, the system temporarily stops execution of the job without switching from the second sheet feeding tray to another tray.

An image processing system includes an image forming device, a sensor, processing circuitry, and an ejection device. The image forming device forms an image based on print information, on a first conveyance medium. The sensor acquires information about the image formed on the first conveyance medium. The processing circuitry causes a second conveyance medium to be ejected in a case where the image formed on the first conveyance medium is a defective image, based on the acquired information. The ejection device stacks the first conveyance medium and the second conveyance medium. The processing circuitry controls display of identification information that distinguishes and associates each one of a plurality of first conveyance media having defective images, with a corresponding one of a plurality of second conveyance media.

An image processing system includes an image forming device, a sensor, and processing circuitry. The image forming device forms an image on a first conveyance medium. The sensor acquires information about the image formed on the first conveyance medium by the image forming device. The processing circuitry performs ejection control to eject a second conveyance medium according to predetermined setting information in a case where the image formed on the first conveyance medium is a defective image, based on the information acquired by the sensor.

An inspection device includes a sensor and processing circuitry. The sensor acquires an image formed on a first conveyance medium. The processing circuitry determines whether the image on the first conveyance medium is defective, based on the image acquired by the sensor. The processing circuitry controls to eject a second conveyance medium in a case where the image on the first conveyance medium is defective. The processing circuitry controls to display an image formed on the second conveyance medium in association with information indicating the first conveyance medium determined to be defective.
