Patent number: 9033487Abstract: A module is configured to selectively apply release agent to a web having a sequence of printed imaged formed thereon by a printer. The module includes a plurality of dispensers arranged in a cross-process direction across the imaged web. The module detects positions of areas in the printed images and determines whether the amount of ink in the areas meet or exceed a predetermined density threshold. If an area meets or exceeds the threshold, a controller operates a dispenser to apply release agent to the area on the web as the area passes the dispenser. The controller operates the dispensers with reference to image data of the surface of the web.Type: GrantFiled: March 14, 2013Date of Patent: May 19, 2015Assignee: Xerox CorporationInventors: Jason M. LeFevre, James M. Chappell, Paul McConville, James E. Williams

Patent number: 8668318Abstract: A leveling and spreading system has been developed that enables the speed and position of the web to be determined from a sensor on a first roller. In a duplex print process, the first roller also reduces a temperature of the media web and an ink image printed in the first side print operation to within a first predetermined temperature range. A second roller modulates the temperature of the media web and ink ejected onto the media web immediately before the web enters the leveling and spreading system to within a second predetermined temperature range to enable uniformity of the ink and web temperatures for spreading the ink in a nip formed with a third roller.Type: GrantFiled: July 26, 2012Date of Patent: March 11, 2014Assignee: Xerox CorporationInventors: James M. Chappell, Jason M. LeFevre, James E. Williams, Paul McConville, Paul S. Bonino, James Spence, Roger G. Leighton, Michael F. Leo, Joseph C. Sheflin, Michael J. Levy, Howard A. Mizes
