An MFP receives print data from an information processing apparatus, such as a mobile terminal or a PC. It is determined whether a predetermined character code is included as content in the received print data. A setting is changed so that the post-processing is performed in a position based on a right end of a printed matter in accordance with the determination before the printed matter is output.

A sheet processing apparatus in which a sheet bundle including a plurality of sheets discharged onto an intermediate processing tray is received in a receiving portion of a stapler and bound with use of a staple, and a sheet bundle including a plurality of sheets discharged onto the intermediate processing tray is received in a receiving portion of a staple-less binding unit having a gap in the thickness direction of the sheets smaller than that of the receiving portion of the stapler and bound without using a staple, wherein when the stapler performs the binding process, the staple-less binding unit is arranged in a position shifted in a width direction orthogonal to a sheet discharge direction from a region on the intermediate processing tray, through which the sheets discharged by a sheet discharging portion pass.

The postprocessing device includes: a stapling unit for stapling a sheet bundle with a staple; a discharge tray to which a bound sheet bundle bound with the staple is to be discharged; a moving member movable in both a direction of approaching the discharge tray and a direction of going away from the discharge tray; and a control section for, when the bound sheet bundle has been discharged, driving the moving member to execute a process of making the moving member hit against the bound sheet bundle or against the discharge tray.

An image forming system comprises an image forming apparatus for forming an image on a sheet and a sheet processing apparatus for performing binding processing on a sheet bundle formed of a plurality of sheets having formed the image. The sheet processing apparatus performs binding processing by a stapler on the sheet bundle placed on an intermediate tray and an opening. The image forming apparatus controls image forming preparation and timing of movement of the stapler in accordance with presence/absence of the sheet bundle on the opening, position of the stapler and timing to obtain an image forming instruction including binding processing.

A sheet processing apparatus in which a sheet bundle including a plurality of sheets discharged onto an intermediate processing tray is received in a receiving portion of a stapler and bound with use of a staple, and a sheet bundle including a plurality of sheets discharged onto the intermediate processing tray is received in a receiving portion of a staple-less binding unit having a gap in the thickness direction of the sheets smaller than that of the receiving portion of the stapler and bound without using a staple, wherein when the stapler performs the binding process, the staple-less binding unit is arranged in a position shifted in a width direction orthogonal to a sheet discharge direction from a region on the intermediate processing tray, through which the sheets discharged by a sheet discharging portion pass.

A sheet post-processing apparatus includes a first regulating device regulating a position of a sheet bundle, by contacting to an end part of the sheet bundle conveyed in a conveying direction by a conveying device and stacked on a stacking device in a direction intersecting with the conveying direction; a second regulating device regulating a position of the sheet bundle in the conveying direction, by contacting to an end part of the sheet bundle stacked on the stacking device in the conveying direction; a first binding device configured to move from one side to another side of the sheet post-processing apparatus and from the other side to the one side by moving in the intersecting direction, and configured to bind a corner part of the sheet bundle using a staple, and a second binding device configured to bind a corner part of the sheet bundle without a staple.

To allow easy access to a jammed sheet when a sheet jam occurs in a sheet processing device installed inside the body of an image forming apparatus. An image forming apparatus is provided with a sheet binding unit that applies binding to sheets. The sheet binding unit has a carry-in port for receiving a sheet to be conveyed to a sheet carry-in path formed thereinside and an openable cover for opening the carry-in port. The end portion of the openable cover on the carry-in port side and an end portion of an operation part for inputting an operational item for the operation carried out in the image forming apparatus are arranged spaced apart from each other at a predetermined distance.

A recording material processing apparatus includes a processing tray, a detecting unit, a stapling unit, an instructing unit, a control unit, a switching unit, and a notifying unit. The detecting unit detects recording material placed in the processing tray. The stapling unit executes a stapling process for the recording material placed in the processing tray. The instructing unit outputs a stapling process execution instruction. Upon receipt of the execution instruction in a state in which the detecting unit has detected a recording material inserted in the processing tray from an outside of a main body of a main body apparatus, the control unit cause the stapling process to be executed. The switching unit switches a position of the stapling unit among a plurality of positions. The notifying unit provides notification of a placement position of the recording material in the processing tray corresponding to each of the plurality of positions.

Disclosed herein is a sheet-binding apparatus. The apparatus has two sheet binding units, each configured to bind the sheets manually inserted from outside. The sheet binding units operate independently, each at the timing appropriate for a specific need.

According to examples, an apparatus may include a processor and a memory. The memory may have stored thereon machine readable instructions that when executed by the processor, may cause the processor to determine a job thickness of a print job including sheets, determine an average sheet thickness of the sheets, and determine an average print material coverage on the sheets. The instructions may also cause the processor to identify, based on the determined job thickness, the determined average sheet thickness, and the average print material coverage, a plurality of correction factors to be applied in a calculation of a corrected stack height of print jobs in an output bin and apply the identified plurality of correction factors to a measured stack height in the output bin to calculate the corrected stack height.
