We describe a print removal device for removing print from a print-carrying medium. In embodiments the print removal device comprises: a feed system for receiving the print- carrying medium and guiding the print-carrying medium through the print removal device; and a system to remove the print from the print-carrying medium, in particular a laser light source for providing a controllable laser light beam to remove the print from the print-carrying medium. Previously used paper for "unprinting" may not be flat and well-behaved, and access may be needed to the full width of the paper creating a section where physical guiding is compromised, and thus the feed system comprises a media guide with an inflection configured to bias the print-carrying medium towards a face of the print-carrying medium which faces away from the laser light source when the print-carrying medium is guided through the print removal device also having the benefit to control the media more accurately to the preferred optical focus plane. We also describe some preferred optical and other device configurations. |
