Abstract
According to embodiments, a sheet post-processing apparatus includes a processing tray, a vertical alignment section, a horizontal alignment section and a controller. The controller is configured to control the horizontal alignment section to shift the sheet to a first alignment position a predetermined distance from the center of the processing tray in the sheet width direction, control the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position, and control the vertical alignment section to align the sheet in the conveying direction at the first alignment position, control the horizontal alignment section to realign the sheet at the first alignment position.
Claims11
An image forming apparatus, comprising:
- a printer configured to form images on a sheet;
- a sheet conveying section configured to convey the sheet output from the printer;
- a processing tray configured to receive the sheet from the sheet conveying section;
- a vertical alignment section configured to align the sheet on the processing tray in a sheet conveying direction by rotation of the vertical alignment section;
- a horizontal alignment section configured to align the sheet, in a sheet width direction orthogonal to the sheet conveying direction, between a first alignment member and a second alignment member;
- a discharge tray;
- and
- a controller configured to control:
- the horizontal alignment section to shift the sheet to a first alignment position that is a predetermined distance from the center of the processing tray in the sheet width direction,
- the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position,
- the vertical alignment section to align the sheet in the conveying direction at the first alignment position,
- determine whether a number of sheets on the processing tray is a predetermined number,
- control the horizontal alignment section to realign the sheet at the first alignment position when the controller determines the number of sheets is the predetermined number, and
- control the conveying section to discharge the sheet to the discharge tray when the number of sheets on the processing tray is not the predetermined number.
A method for controlling an image formation process of an image forming apparatus, the method comprising:
- forming images on a sheet with a printer;
- conveying the sheet output from the printer with a sheet conveying section to a processing tray;
- receiving the sheet from the sheet conveying section at the processing tray;
- aligning the sheet on the processing tray in a sheet conveying direction using rotation of a vertical alignment section;
- aligning the sheet on the processing tray, in a sheet width direction orthogonal to the sheet conveying direction, between a first alignment member and a second alignment member using a horizontal alignment section;
- shifting the sheet to a first alignment position that is a predetermined distance from the center of the processing tray in the sheet width direction using the first alignment member and the second alignment member;
- receiving the sheet discharged from the processing tray at a discharge tray;
- determining whether a number of sheets on the processing tray is a predetermined number;
- aligning the sheet at the first alignment position using the horizontal alignment section when the number of sheets on the processing tray is the predetermined number;
- and
- discharging the sheet to the discharge tray when the number of sheets which on the processing tray is not the predetermined number.
An image forming apparatus, comprising:
- a printer configured to form images on a sheet;
- a sheet conveying section configured to convey the sheet output from the printer
- a processing tray configured to receive the sheet from the sheet conveying section;
- a vertical alignment section configured to align the sheet on the processing tray in a sheet conveying direction by rotation of the vertical alignment section;
- a horizontal alignment section configured to align the sheet, in a sheet width direction orthogonal to the sheet conveying direction, between a first alignment member and a second alignment member;
- and
- a controller configured to control:
- the horizontal alignment section to shift the sheet to a first alignment position that is a predetermined distance from the center of the processing tray in the sheet width direction,
- the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position, and
- the vertical alignment section to align the sheet in the conveying direction at the first alignment position, wherein
- the controller is further configured to control the horizontal alignment section to align the sheet in the sheet width direction at a second alignment position, which is different from the first alignment position, before shifting the sheet to the first alignment position.
