Abstract
An image processing system includes an image forming unit, an image decoloring unit, a first sheet stacking unit, a second sheet stacking unit, a first detector for the first sheet stacking unit, a second detector for the second sheet stacking unit, and a control unit. The control unit controls a transport path of a sheet discharged from one of the image forming unit and the image decoloring unit.
Claims16
An image processing system comprising:
- an image forming unit;
- an image decoloring unit;
- first and second sheet stacking units, one of the first and second sheet stacking units being a movable tray that moves in a vertical direction;
- a first sheet detector for the first sheet stacking unit, the first sheet detector being disposed in the movable tray;
- a second sheet detector for the second sheet stacking unit;
- and
- a control unit configured to control a transport path of a sheet discharged from one of the image forming unit and the image decoloring unit, so that
- the sheet is transported to the first stacking unit when:
- (i) the first sheet detector does not detect a sheet in the first stacking unit, (ii) the second sheet detector detects a sheet in the second stacking unit, and (iii) the sheet in the second stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit,
- the sheet is transported to the second stacking unit when:
- (i) the first sheet detector detects a sheet in the first stacking unit, (ii) the second sheet detector does not detect a sheet in the second stacking unit, and (iii) the sheet in the first stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit,
- the sheet is transported to the moveable tray when:
- (i) the first sheet detector detects that the sheet is present on the movable tray, (ii) the previous job is a decoloring job, and (iii) the decoloring job is performed, and
- the sheet is transported to a non-moveable sheet stacking unit when:
- (i) the first sheet detector detects that the sheet is present on the movable tray, (ii) the previous job is an image forming job, and (iii) the image forming job is performed.

A sheet transport method comprising:
- detecting, with a first sheet detector, a presence or absence of a sheet on a first sheet stacking unit;
- detecting, with a second sheet detector, a presence or absence of a sheet on a second sheet stacking unit, one of the first and second sheet stacking units being a movable tray that moves in a vertical direction, the first sheet detector being disposed in the movable tray;
- and
- controlling a transport path of a sheet discharged from one of an image forming unit and an image decoloring unit, so that
- the sheet is transported to the first stacking unit when:
- (i) the first sheet detector does not detect a sheet in the first stacking unit, (ii) the second sheet detector detects a sheet in the second stacking unit, and (iii) the sheet in the second stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit,
- the sheet is transported to the second stacking unit when:
- (i) the first sheet detector detects a sheet in the first stacking unit, (ii) the second sheet detector does not detect a sheet in the second stacking unit, and (iii) the sheet in the first stacking unit is a sheet discharged from the other one of the image forming unit and the image decoloring unit,
- the sheet is transported to the moveable tray when:
- (i) the first sheet detector detects that the sheet is present on the movable tray, (ii) the previous job is a decoloring job, and (iii) the decoloring job is performed, and
- the sheet is transported to a non-moveable sheet stacking unit when:
- (i) the first sheet detector detects that the sheet is present on the movable tray, (ii) the previous job is an image forming job, and (iii) the image forming job is performed.
