Abstract
A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit, and a controller. The decoloring unit decolors the image on the sheet conveyed through the sheet conveying unit. The decoloring unit is positioned downstream of the scanner in a sheet conveying direction. A distance along the sheet conveying direction between the scanner and the decoloring unit is shorter than a length of a first predetermined sheet size and longer than a length of a second predetermined sheet size. A controller determines whether the sheet conveyed by the sheet conveying unit is the first predetermined sheet size or the second predetermined sheet size. The controller performs a mode limiting process if the sheet size is determined to be the first predetermined sheet size.
Claims14
A method for controlling a decoloring apparatus which includes a decoloring unit positioned downstream of a scanner in a sheet conveying direction, a distance along the sheet conveying direction between the scanner and the decoloring unit being shorter than a length of a first sheet size and longer than a length of a second sheet size, the method comprising:
- determining a size of the sheet to be conveyed;
- accepting an input selecting a decoloring mode;
- controlling an available scanning mode of the decoloring apparatus based on the determined sheet size and the selected decoloring mode;
- accepting an input selecting the available scanning mode;
- conveying the sheet through the scanner and the decoloring unit;
- controlling the scanner based on the selected available scanning mode;
- and
- controlling the decoloring unit to perform decoloring.
