An image forming apparatus 100 allowing insertion of an insert-sheet between discharged sheets of recording paper includes: an image forming unit 122 forming an image on the recording paper; an operation unit 130 designating an insertion position for inserting the insert-sheet; a discharge unit discharging the sheets of recording paper having images formed and the insert-sheet; and a control unit 102 controlling timing for inserting the insert-sheet. The insertion position is designated by a copy-by-copy basis with one copy being a set of sheets of recording paper having all images included in a job instructing image formation on the recording paper formed thereon. The control unit 102 controls the discharge unit such that the sheets of recording paper having the image formed thereon are discharged by the number determined from the insertion position and thereafter the insert-sheet is discharged.

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.

A sheet conveyance apparatus which conveys sheets fed from a first sheet feeding unit and sheets fed from a second sheet feeding unit to a merging point, inserts the sheets fed from the first sheet feeding unit into the sheets fed from the second sheet feeding unit in a predetermined order at the merging point, and discharges the sheets fed from the first sheet feeding unit and the sheets fed from the second sheet feeding unit to a downstream side includes: a jam detecting unit configured to detect a jam of a sheet in the first sheet feeding unit; and a control unit configured to newly feed sheets which are before the predetermined order, in which a sheet causing the jam is supposed to be inserted, and have not been fed from the second sheet feeding unit, and convey the newly fed sheets to the downstream side.

A printing apparatus includes a drying unit that dries a medium, a controller that controls to output a partition sheet as a partition of the medium on which printing based on a print job has been performed, and a liquid application unit that applies liquid onto the partition sheet.

System and methods for reconstructing a suspended print job. In one embodiment, a print controller receives a print job, and initiates construction of a sheet based on logical pages of the print job. Print controller determines a sheet number for the sheet that identifies a page number of one or more logical pages related to the construction of the sheet, an offset for the sheet that identifies an order of the sheet with respect to other sheets that share the sheet number. Print controller also assigns a sheet identifier to the sheet that includes the sheet number and the offset, and receives the sheet identifier in response to a determination to resume the print job from a suspended state. Print controller initiates processing for resuming the print job from the sheet based on the sheet number and the offset in the sheet identifier.

A sheet conveyance apparatus which conveys sheets fed from a first sheet feeding unit and sheets fed from a second sheet feeding unit to a merging point, inserts the sheets fed from the first sheet feeding unit into the sheets fed from the second sheet feeding unit in a predetermined order at the merging point, and discharges the sheets fed from the first sheet feeding unit and the sheets fed from the second sheet feeding unit to a downstream side includes: a jam detecting unit configured to detect a jam of a sheet in the first sheet feeding unit; and a control unit configured to newly feed sheets which are before the predetermined order, in which a sheet causing the jam is supposed to be inserted, and have not been fed from the second sheet feeding unit, and convey the newly fed sheets to the downstream side.
