  • System and method for optimizing printing throughput and print quality by evaluating image content
    Patent number: 8075129
    Abstract: A method adjusts operation of a printer in accordance with an analysis of image content used to generate printed images. The method includes measuring image content of a first print image, comparing the measured image content to a predetermined threshold, and altering a print process parameter to adjust operation of a printer component in response to the measured image content exceeding the threshold.
    Type: Grant
    Filed: March 31, 2009
    Date of Patent: December 13, 2011
    Assignee: Xerox Corporation
    Inventors: Jeffrey Russell Kohne, Trevor James Snyder, Audrey Ann Lester, Brent E. Fleming, Paul L. McConville, Walter Sean Harris, Brent R. Jones
  • Method for lubricating a transfer roller with an image member
    Patent number: 7942517
    Abstract: A method is implemented by a printer to move a transfix roller selectively to clean the transfix roller. The transfix roller is moved from a transfix nip with the print drum to a position where the transfix roller remains in rolling contact with the print drum, but exerts a pressure on the print drum that is less than the transfix pressure. The transfix roller is later moved out of rolling contact with the print drum in response to the transfix roller rotating a predetermined distance.

  • System and method for lubricating a transfer roller with an image member
    Patent number: 7798631
    Abstract: Ghosting conditions occur less frequently during duplex printing when a transfix roller in a printer is enabled to remain in rolling contact with release agent on a print drum after a trailing edge of a media sheet has left a transfix nip between the transfix roller and the print drum.
