Patent number: 9205676Abstract: An aqueous inkjet printer is provided with a surface energy applicator that is positioned to treat the surface of a blanket immediately prior to a printhead ejecting ink onto the blanket. Modifying the surface energy of blanket with the electric field and charged particles produced by the applicator affects the adhesion of the ink to blanket. This adhesion changes from the impact of the ink on the blanket until the ink image is transferred to media. The surface energy applicator is operated during each print cycle to alter the surface energy of the blanket for each ink image formed on the blanket.Type: GrantFiled: June 4, 2014Date of Patent: December 8, 2015Assignee: Xerox CorporationInventors: Christopher A. DiRubio, Paul J. McConville, Christopher G. Lynn, Anthony S. Condello

Patent number: 8833895Abstract: An image transfer system for use in an indirect printer includes a support roller for a transfix roller. The support roller is configured to apply pressure to a center portion of a nip formed between a transfix roller and an imaging drum while the transfix roller applies pressure to the ends of the nip. This configuration is particularly advantageous for use with imaging drums and transfix rollers having thin walls.Type: GrantFiled: May 4, 2012Date of Patent: September 16, 2014Assignee: Xerox CorporationInventors: Bruce E.

Patent number: 8396404Abstract: Disclosed are methods and apparatus for marking an image on a media substrate using an intermediate transfer printing arrangement. Specifically disclosed is an image transfer nip arrangement associated with a secondary transfer of an image which utilizes a constant current source to generate an electric field across the nip and transfer toner from an intermediate transfer surface to a media substrate.Type: GrantFiled: August 26, 2010Date of Patent: March 12, 2013Assignee: Xerox CorporationInventors: Charles H.

Publication number: 20120308274Abstract: An electrostatographic printing apparatus that includes a charge receptor endless belt; a transfer nip including a BTR roll in contact with the charge receptor at a transfer zone, a continuous media supplied to the transfer zone, and the transfer nip adapted for systematic engagement and disengagement with the continuous media for synchronization of image transfer from the charge receptor to the media. More specifically, in response to recognition of imaging inconsistencies such as belt seams, test patches, or label format pitches, the endless belt disengages from the continuous media at the BTR roll. The BTR roll is appropriately turned on and off and the continuous media reversed in direction commonly known as a ‘Pilgrim step’, then returned to normal direction to synchronize the transfer of images to the continuous media.Type: ApplicationFiled: June 3, 2011Publication date: December 6, 2012Applicant: XEROX CORPORATIONInventors: Roger G.

Publication number: 20120121276Abstract: A method and apparatus can, while operating a printing device in a test mode, supply a changed transfer field to a marking material transfer device. The changed transfer field is less than or more than the standard transfer field. The method and apparatus disable operations of other marking material transfer devices of the printing device to isolate the marking material transfer device. Further, the method and apparatus compare the actual amount and/or spatial distribution of marking material transferred to a recipient surface (to which the first marking material transfer device transfers the marking material) against a predetermined standard. Then, if the actual amount of marking material transferred to the recipient surface is different than the predetermined standard, the method and apparatus can identify the first marking material transfer device as being a potential source of printing defects.Type: ApplicationFiled: November 15, 2010Publication date: May 17, 2012Applicant: XEROX CORPORATIONInventors: Christopher A.
