An image forming apparatus includes a sheet stacking portion, an image forming portion, a detection portion configured to detect a position, in a sheet width direction, a storage configured to store position information of a sheet, and a controller. The controller is configured to cause the storage to store the position information based on a position of a sheet detected by the detection portion during execution of the job, and if sheet information of a sheet used in a previous job is matches sheet information of a sheet used in a current job, cause the image forming portion to start formation of an image to be formed on a first sheet, before a position of the first sheet is detected by the detection portion, based on the position information stored in the storage in the previous job.

A sheet stacker includes a sheet stacking member, a biasing force applier, an angle setter, and a regulator. The sheet stacking member has an upstream portion in a sheet conveyance direction. The upstream portion is movable in a vertical direction. The biasing force applier is configured to apply a biasing force to bias the sheet stacking member upward. The angle setter is configured to set an angle of the sheet stacking member in the sheet conveyance direction, relative to a sheet conveying portion, between a first angle and a second angle. The regulator is configured to regulate movement of the sheet stacking member in a case in which the upstream portion of the sheet stacking member is located closer to the sheet conveying portion at either the first angle or the second angle.

A printing apparatus includes a printing unit that prints images on sheets, a sheet processing unit that executes bookbinding processing on sheets on which images have been printed by the printing unit, a stack control unit that stacks, in a stacking unit, bookbinding products on which bookbinding processing has been executed by the sheet processing unit, a setting unit that sets whether or not to activate a stacking limit of bookbinding products to be stacked on the stacking unit by the stack limiting unit, and a control unit that performs control so as to stop stacking in the stacking unit by the stack control unit in accordance with the stacking limit in the case where the stacking limit of bookbinding products has been set to activated by the setting unit.

A sheet conveyance apparatus include a first conveyance unit, a second conveyance unit including a cover and configured to be movable between a first position where a sheet conveyed from the first conveyance unit can be conveyed to a sheet conveyance path and a second position separated from the first position, and a retaining portion configured to retain the cover at an open position and to retain the second conveyance unit at the second position through the cover retained at the open position in a case where the cover is positioned at the open position in a condition in which the second conveyance unit is positioned at the second position.

According to an embodiment, a sheet processing apparatus includes a transport unit and a holding unit. The transport unit transports a first sheet to a first position. The transport unit transports a second sheet, which is transported after the first sheet, to a second position displaced to the upstream side of a sheet transport direction relative to the first position. The transport unit transports a third sheet, which is transported after the second sheet, to a third position displaced to the downstream side of the sheet transport direction relative to the second position. In the case where the second sheet is transported to the second position, the holding unit holds the first sheet at the first position. In the case where the third sheet is transported to the third position, the holding unit holds the second sheet at the second position.

A discharge unit discharges the sheet has an image. A switching unit switches between stacking the sheet discharged from the discharge unit on a stacking unit or conveying the sheet the discharge unit toward an image reading apparatus. A conveyance unit conveys the sheet conveyed via the switching unit to a reading unit. A cooling unit cools the sheet discharged from the discharge unit or cools the reading unit.

The present invention provides a sheet storage device having a high sheet receiving performance and whose size is reduced. A point 272 of intersection of a first upper guide and a second upper guide is located upstream from a point 271 of intersection of a first lower guide and a second lower guide in a sheet conveyance direction. Thus, the size of the sheet storage device can be reduced while the sheet receiving performance remains unaffected.

A sorting device includes a base portion and a tray portion. The tray portion is supported on the base portion to be reciprocatable between a first shift position, where the tray portion is located at one side in the sheet width direction, and a second shift position, where the tray portion is located at the other side in the sheet width direction. The tray portion has a cutout portion. The cutout portion is formed by cutting away, with a predetermined width, an end part of the tray portion in the sheet width direction inward across the tray portion. With the tray portion at the second shift position, the cutout portion is located below one side end edge of the sheet in the sheet width direction, of sheets stacked on the tray portion.

A print control method includes, when a sorting method for sorting printed matters in a printing device is set, displaying an image indicating an output aspect of the printed matters output from the printing device, based on the set sorting method and a previous output aspect of the printing device.

A sheet stacking apparatus, including: a movable stack portion on which sheets are to be stacked; a detection portion configured to detect whether or not a topmost sheet of sheets stacked on the stack portion is positioned at a predetermined position; and a control portion configured to position the topmost sheet at the predetermined position based on a detection result of the detection portion, wherein in a case where the control portion moves the stack portion at a first speed so that a topmost sheet on the stack portion deviates from the predetermined position, the control portion moves the stack portion at a second speed lower than the first speed to position the topmost sheet at the predetermined position.
