A sheet stacking apparatus has a stack tray which can move so that a sheet stack surface keeps a constant position from a discharge outlet and which is a finisher capable of using the stack tray by switching it. When stacking the maximum number of sheets to be stacked on the stack tray and preventing stacking of sheets on the stack tray up to the maximum number of sheets to be stacked and the number of sheets stacked on the stack tray reaches a predetermined number of sheets to be stacked which does not prevent up to the maximum number of sheets from being stacked on the stack tray, stacking of sheets on the stack tray is temporarily prohibited to stack sheets by switching to the stack tray. Thereby, all sheet stack trays can stack up to the maximum number of sheets to be stacked, decrease of the number of stacked sheets is prevented in the whole sheet stacking apparatus and the number of temporal interruptions of a job is decreased.

An image forming apparatus that enables a post-processing apparatus to perform optimum control in accordance with the type (thickness) of sheet. A user sets on an image forming apparatus main unit 10 a thickness of sheet to be conveyed. A CPU circuit section 150 obtains first thickness-determination information used for the sheet conveying speed control in a finisher 500 from the finisher 500. A plurality of candidate sheet thicknesses that can be set, are determined based on the first thickness-determination information obtained by the CPU circuit section 150 and second thickness-determination information used when image-forming process speed control is performed in the image forming apparatus main unit 10 according to sheet thickness.

摘要:
A sheet processing apparatus which can be reduced in size and suppress cost increase by preventing sheet buckling and jamming. Sheets stacked on an insert tray of a sheet processing apparatus are fed on a conveying path in a first sheet feed mode in which sheets are fed after being inverted by an inversion path or a second sheet feed mode in which sheets are fed without passing through the inversion path. A pair of conveying rollers conveys the fed sheets and the sheets with images formed thereon. The conveyed sheets are stacked on a processing tray, and a stapler performs predetermined processing on the stacked sheets. It is determined whether predetermined information is included in sheet information about the sheets stacked on the insert tray, and if the predetermined information is included in the set sheet information, a predetermined message is displayed on a display panel.

In a sheet conveyance system in which a plurality of apparatuses each including a communication unit with a plurality of communication channels are connected, and a sheet is conveyed between the apparatuses, each of the plurality of communication channels can be switched between a transmission mode and a reception mode. When a plurality of transmission channels are set by channel assignment, communication can be executed by giving a priority to each transmission destination. If transmission data are accumulated in an apparatus, and they include data for a transmission destination with a higher priority over the current data transmission destination, the number of transmission channels is increased, and the priority is raised.

In an image forming apparatus which requires the user to manually input sheet medium information, (when a bundle of sheets which include a plurality of types of print media are to be printed, the user must manually input setups of the image forming apparatus for each individual print medium. In manual setups by the user, some setups require user's knowledge about print media. When the user has made wrong setups, a print result cannot be obtained under an appropriate control condition Furthermore, when information about a print medium is sensed by the sensor without manual setups, the information cannot be often precisely detect depending on the type and thickness of the print medium, an environment, and the like, and it is consequently difficult to attain optimal image formation. It is an object of this invention to attain optimal image formation, saving user labor and shortening the print time by using a radio tag attached to the sheet medium. An image forming apparatus which forms an image on a sheet medium, has means for reading information from a information holding means, such as a minuscule radio chip, attached to the sheet medium, and means for manually inputting information of the sheet medium, and controls an image forming condition using either information.
摘要:
A sheet processing apparatus which is capable of discharging a sheet at the optimum sheet discharging speed without stopping the conveyance of the sheet irrespective of differences in sheet conveying speed according to sheet types. A sheet discharging motor is controlled to drive a discharging roller to convey sheets in selected one of a first state in which the sheets are conveyed at speeds within a first speed range specified by a first maximum speed and a first minimum speed, and a second state in which the sheets are conveyed at speeds within a second speed range specified by a second maximum speed lower than the first maximum speed and a second minimum speed lower than the first minimum speed. The first speed range includes an overlapping range where the first speed range and the second speed range overlap.

An image forming apparatus has a sheet processing unit for feeding a cover sheet and a folder for folding the cover sheet with a bundle of recording sheets. The sheet processing unit has a cover sheet feeder for feeding a cover sheet facing upward toward an image forming unit, a reversing unit for reversing the cover sheet so that the cover sheet faces downward, and a conveyor for conveying the reversed cover sheet to the folder in a switchback manner so that the front face of the cover sheet faces the folding roller pair. The folder has a thrusting member for thrusting the bundle of sheets toward the folding roller pair and discharging the folded bundle to a discharge tray.
