Abstract:
1. A printing media recycling apparatus, comprising: a printing-medium feeding section configured to feed a recycling target printing medium to a conveying path; a scanner section configured to read an image of the printing medium conveyed on the conveying path and generate image data, the scanner section being arranged on the conveying path; a decoloring section configured to heat the printing medium conveyed on the conveying path to execute decoloring processing for an image formed of a decolorable recording material on the printing medium, the decoloring section being arranged downstream from the scanner section on the conveying path; a decoloring-processing-execution determining section configured to determine, on the basis of the image data generated by the scanner section, whether the execution of the decoloring processing is appropriate for the printing medium or the execution of the decoloring processing is unnecessary; a decoloring determining section configured to determine a decolored state of the printing medium after the execution of the decoloring processing by the decoloring section; and a diverting-section-switching control section configured to switch, according to results of the determination by the decoloring-processing-execution determining section and the decoloring determining section, a diverting section to lead the printing medium to a predetermined discharge tray, wherein the decoloring-processing-execution determining section includes a base-density detecting section and, if the base-density detecting section determines that there is a portion where density of a base of the printing medium is outside a range of a specified value, determines that the execution of the decoloring processing is inappropriate.
