Patent number: 8783857Abstract: Systems for leveling UV-curable gel ink include a leveling member having a conformable surface. The leveling member is a quartz tube rotatable about a longitudinal axis, and connected to a mandrel, with conformable VITON O-rings interposing the mandrel and the quartz tube. A UV source is disposed within the quartz tube, and configured to emit light through the quartz tube and the conformable surface onto a surface of a substrate passing through a leveling or pressure nip defined by the quartz tube and a backing member or pressure belt.Type: GrantFiled: June 15, 2012Date of Patent: July 22, 2014Assignee: Xerox CorporationInventors: Bryan J.

Patent number: 8565657Abstract: According to various illustrative embodiments, an apparatus for redistributing release agent on a fuser surface of an image forming device is provided. The apparatus includes a fuser surface for contacting a sheet of media having an image formed thereon by the image forming device, the fuser surface moving in a traveling direction; and a flexible blade for redistributing the release agent on the fuser surface from a first post-fusing distribution to a second distribution, the flexible blade contacting the release agent on the fuser surface at a contact area and pressing the release agent against the fuser surface to redistribute the release agent from the first post-fusing distribution to the second distribution, wherein the flexible blade is adapted to redistribute the release agent such that the second distribution is more uniform across the fuser surface than the first post-fusing distribution.Type: GrantFiled: October 28, 2010Date of Patent: October 22, 2013Assignee: Xerox CorporationInventors: Augusto E. Barton, James Padula

Publication number: 20070182800Abstract: A release agent applicator applies release agent to an imaging drum and absorbs release agent metered from the drum to extend the operational life of a image drum maintenance unit. The applicator includes a reservoir for storing release agent, the reservoir having a plurality of perforations for enabling release agent to seep from the reservoir, a containment membrane mounted to the reservoir for wicking release agent from the perforations of the reservoir, and a delivery layer mounted to the containment membrane for delivering release agent from the containment membrane to an imaging drum that is in contact with the delivery layer. The delivery layer is matched to the containment membrane to maintain a saturation rate for the delivery layer in a predetermined range and the delivery layer has an uptake rate for release agent contacting an external boundary of the delivery layer that is greater than a release agent supply rate from the containment membrane to the delivery layer.Type: ApplicationFiled: February 6, 2006Publication date: August 9, 2007Inventors: Alexander Fioravanti, Paul McConville, James Padula, Michael Levy

Publication number: 20070177913Abstract: Disclosed herein are several embodiments to facilitate the characterization of fuser stripping performance. Recognizing that the characteristics of a substrate exiting a fusing nip are indicative of the operation of the nip and the stripping operation itself, several contact and non-contact sensing methods are described to detect or predict degraded stripping performance, thereby permitting one or more compensation techniques to be employed, or to identify the need for fuser subsystem replacement.Type: ApplicationFiled: January 31, 2006Publication date: August 2, 2007Applicant: Xerox CorporationInventors: Steven Russel, Mansour Messalti, Jeremy deJong, Anthony Condello, Daniel McVeigh, Donald Bott, James Padula
