  • Publication number: 20190248168
    Abstract: To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.

  • Publication number: 20190248615
    Abstract: To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, a post-processing control section receives information on an ink discharge amount, the number of sheets, sheet type, and printing mode (two-side/one-side) in printing on sheets from a main body control section of an image forming unit A, in forming a bunch of sheets on the processing tray. The control section thereby recognizes weight of a bunch of sheets formed on the processing tray, and when the section determines that the weight is heavier than predetermined weight, decreases a rotation velocity of a drive motor of a sheet bunch transport means, or increases a current amount applied to the drive motor. By this means, torque of the motor is increased, and the bunch of sheets is reliably discharged to the first stack tray.

  • Patent number: 10160249
    Abstract: A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

  • Patent number: 8172214
    Abstract: A sheet collecting apparatus has a sheet transport path for transporting a sheet, a tray device for bearing and storing sheets, a regulation stopper for regulating the sheet, a holding path to temporarily hold a sheet, an alignment roller to transport the sheet, and a control device for controlling transport of the sheet. The alignment roller adjusts a level of pressing force acting on the sheet transported onto the tray device. The control device has a first operation mode and a second operation mode. In the first operation mode, the alignment roller applies a transport force to the sheet by a predetermined pressing force after a rear end of the sheet is carried into the tray device, while in the second operation mode, changing the pressing force applied to the sheets from the alignment roller from a first pressing force to a second pressing force and applying varied transport force.
