Abstract:
1. A system for sorting printed pages according to reusability, comprising: a duplex scanning document handler that receives and scans both sides of a plurality of unsorted used pages and detects print on zero or more sides of the pages; a sorting module including a processor that executes computer-executable instructions for: determining whether one or more sides of an unsorted page is printed; and sorting each page according to a number of sides on which print is detected; wherein the sorting module: routes duplex printed pages with print on both sides to a first tray; orients simplex printed pages with print on only one side to face the printed side downward and routes the oriented pages to a second tray; and routes pages with no print on either side to a third tray; and a printer that prints a security pattern over text on a the printed side of the simplex printed pages, wherein the security pattern renders the text illegible.
