A sheet stacking apparatus includes a discharge unit, a stacking tray, an acquisition unit, a shift control unit, and an alignment unit. The shift control unit controls a stacking position of a sheet in a sheet width direction in response to shift information acquired by the acquisition unit. The alignment unit aligns a sheet staked on the stacking tray and moves to a position that abuts on a side edge of the sheet in the sheet width direction to align the sheet. The shift control unit controls a stacking position of a second sheet to stack the second sheet on a second position or on a first position depending on where a first sheet is stacked and on shift information of the second sheet.

A sheet conveying system which is capable of preventing a jammed sheet from being mixed with processed sheets, reducing waste in sheets and toners, and further alleviating the user's operations, when jamming has occurred during passing of a sheet between respective sheet conveying devices of upstream and downstream apparatuses. A puncher control section of a puncher as an upstream apparatus of the system issues a passing completion notification as to the passing of a sheet to a staple stacker control section of a staple stacker as a downstream apparatus of the system. Upon reception of the notification, when the staple stacker control section determines that the parameter of auxiliary information of the notification indicates an abnormal discharge of the sheet from the puncher, the staple stacker stops the conveyance of the sheet.

A sheet processing apparatus capable of maintaining alignment of sheets of a sheet bundle on a processing tray even in a job uses sheets including particular sheets. In the sheet processing apparatus (finisher), a sheet conveyed along a conveying path is retained in a buffer path. The sheet and the following sheet are stacked on a processing tray in a state superposed with a shift in a conveying direction. A finisher controller determines in advance, before a conveyed sheet reaches the buffer path, whether or not the sheet is a particular sheet having a protrusion. When the sheet retained in the buffer path and the following sheet are to be superposed one upon the other, the amount of the shift between the sheets in the conveying direction is controlled according to a result of the determination by the finisher controller.

An image forming system is provided that alleviates throughput reductions and enables reductions in power consumption and lower noise. The image forming system includes an image forming apparatus that forms an image on a recording material and a plurality of sheet-conveying devices that convey the recording material. Furthermore, the image forming apparatus includes a storage unit configured to store connecting orders of the plurality of sheet-conveying devices and a determination unit configured to determine which of the sheet-conveying devices should be given notification by an operation start request or an operation end request according to designation information that designates the sheet-conveying device to which the recording material is conveyed and the connecting orders for the plurality of sheet-conveying devices. Further still, the image forming apparatus includes a transmitting unit configured to transmit an operation start request or an operation end request to each determined sheet-conveying device.

A finisher according to an aspect of the invention includes an intermediate tray that collects sheets to form a sheet bundle, a sheet gripping member that grips one end of the sheet bundle in a conveying direction and a positioning member that grips the other end of the sheet bundle in a conveying direction, a moving portion that moves the sheet gripping member and the positioning member to come close each other, a pair of folding rollers that folds the sheet bundle while conveying the sheet bundle, a projecting member that projects a part between the one end and the other end of the gripped sheet bundle toward the pair of folding rollers, a controller that controls the moving portion, such that the sheet gripping member and the positioning member come close each other in synchronization with an operation of projecting the projecting member toward the sheet bundle S.
摘要:
An image forming apparatus which makes it possible to perform image forming processing and post-processing efficiently. A job controller divides a single print job into a plurality of print jobs according to the processing capability of a post-processing apparatus. A print controller causes a printer section to perform sequential operations according to the split print jobs, to form a plurality of sets of printed sheet bundles. The sets of sheet bundles formed in association with the respective print jobs and stacked on a stacker by the operation of the print controller are sequentially brought to the post-processing apparatus, and the post-processing apparatus sequentially performs post-processing on the supplied sets of sheet bundles.
摘要:
An image forming apparatus in which surplus tabbed sheets produced in one set of output can be utilized for the next set of output, without requiring a user to perform a laborious task. In the image forming apparatus, a CPU calculates the number of tabbed sheet groups which will be used for one set of image formation and the number of tabbed sheets which will be used from among the last tabbed sheet group. Among the last tabbed sheet group, surplus tabbed sheets which will be left unused in the one set of image formation are determined. If the number of tabbed sheets is equal to or less than the number of the surplus tabbed sheets, at least one of the surplus tabbed sheets is used to carry out two sets of image formation.
摘要:
An image forming apparatus has a calibration mode in which a calibration image is formed on a print medium to correct image forming conditions. The image forming apparatus detects print medium information to determine, on the basis of the print medium information, whether the print medium is a sheet recommended as a print medium for use in the calibration mode. The image forming apparatus sets calibration conditions corresponding to the determined recommended sheet. The image forming apparatus corrects the image forming conditions on the basis of the set calibration conditions.

An image forming system that has an apparatus that receives recording media from an apparatus upstream from it, executes image formation processing, and conveys the recording media to an apparatus positioned downstream from it. The apparatus controls whether to continue conveyance of recording media, change their discharger, and accept recording media in accordance with condition of its own or the downstream apparatus regardless of the configuration of the entire system.
