  • Publication number: 20110089623
    Abstract: A sheet processing apparatus which is capable of improving the productivity of sheet processing as much as possible. An image forming apparatus forms an image on a sheet. A finisher is connected downstream of the image forming apparatus and performs post processing on the sheet. The finisher moves at least one of the sheet and a punching unit to adjust a position for punching holes in the sheet. The finisher determines whether or not a post-processing apparatus connected upstream of the finisher is provided with a correction mechanism for correcting a position of a sheet in a direction orthogonal to a sheet conveying direction. When the post-processing apparatus is provided with the correction mechanism, the finisher causes the image forming apparatus to be set such that a sheet conveying interval becomes shorter than when the post-processing apparatus is not provided with the correction mechanism.

  • Patent number: 7918450
    Abstract: When a sheet is conveyed to a position where a conveying speed can be changed from a first conveying speed to a second conveying speed while a discharging unit is discharging a preceding stack of sheets, a conveyance control unit calculates a third conveying speed for conveying the sheet based on a first conveyance time to be taken until a leading end of the stack of sheets reaches a second tray unit from a first tray unit and a second conveyance time to be taken until a current discharging operation is completed from a start of the current discharging operation, and changes the conveying speed from the first conveying speed to the third conveying speed.
