Patent number: 7257357Abstract: Embodiments herein comprise a charging station adjacent a photoreceptor. The charging station is adapted to charge the document zone of the photoreceptor with a first negative voltage and to charge the inter-document zone of the photoreceptor with a second negative voltage that is more negative than the first negative voltage. The second more negative voltage reduces the amount of positive charges trapped within layers of the inter-document zone of the photoreceptor. Thus, when the charging station increases the size of the document zone from a smaller size associated with a smaller printing medium to a larger size associated with a larger printing medium, by reducing the positive charges from being trapped within layers of the inter-document zone of the photoreceptor, ghosting is reduced on the larger printing medium.Type: GrantFiled: May 17, 2005Date of Patent: August 14, 2007Assignee: Xerox CorporationInventors: Douglas A. Lundy, Michael J. Turan, Huoy-Jen Yuh, Moritz Wagner

Patent number: 7218886Abstract: A method for removing a residue, such as lateral charge migration (LCM) film, from an imaging member includes contacting at least a portion of the imaging member with a wash liquid capable of removing the residue. The wash liquid containing the residue is then removed, for example, by applying an absorbent material such as a toner, to the contacted portion of the imaging member.Type: GrantFiled: July 20, 2004Date of Patent: May 15, 2007Assignee: Xerox CorporationInventors: Robert E. Hildebrand, Joseph M. Wing, Randall C. Ryon, John R. Lambie, Moritz P. Wagner, Huoy-Jen Yuh, Douglas A. Lundy, Michael J. Turan, Eric Bonn
