Abstract
A decoloring apparatus includes a reading unit that reads an image formed on a sheet and outputs image information corresponding to the read image. A control unit is configured to recognize the image information output by the reading unit and determine whether decoloring using the decoloring unit is performed on the sheet based on the recognized image information.
Claims14
A decoloring apparatus comprising:
- a decoloring unit configured to perform a decoloring processing for decoloring an image formed on a sheet;
- a reading unit;
- and
- a controller configured to:
- after the decoloring unit performs the decoloring processing on the sheet, control the reading unit to read a surface of the decolored sheet and output image information corresponding to the read surface of the decolored sheet,
- determine a decoloring ratio of an area of the decolored image on the surface of the decolored sheet to an entire area of the surface of the decolored sheet based on the output image information, and
- determine whether the decolored sheet is reusable based on the determined decoloring ratio.
