  • Publication number: 20190010015
    Abstract: A media processing device includes: a transport assembly to guide a media unit from a source past a processing head in an outbound direction, and past the processing head in a return direction toward an output; and a redirector to receive the media unit in the outbound direction, flip the media unit, and expel the media unit in the return direction. The redirector includes: a motor having an output shaft; a carriage rotatably supported by a housing; a roller supported by the carriage for engaging with the media unit; and a selector connected between the output shaft and the roller. The selector, for a first output shaft drive direction, rotates relative to the carriage and drives the roller for receiving or expelling the media unit, and for a second output shaft drive direction, engages the carriage and rotates the carriage relative to the housing for flipping the media unit.

  • Patent number: 7170537
    Abstract: A card-cleaning assembly for printers is provided. The assembly can be used in any suitable card printing apparatus, particularly thermal dye printers. Such card printers are used to print driver's licenses, employee badges, student cards, and the like. The assembly includes a card-cleaning roller and an adhesive tape cartridge. The cleaning roller contacts the card and removes dust and dirt particles and other debris from the surface of the card. The tape cartridge is attached to a pivoting arm on the printer which pivots so that the adhesive tape engages the cleaning roller and removes the debris from the roller as the roller rotates.
