Patent number: 9327526Abstract: Embodiments described herein are directed to a system for reducing electrostatic fields underneath print heads in a direct marking printing system. The system includes: one or more print heads for depositing ink onto a media substrate; a media transport for moving the media substrate along a media path past the one or more print heads; a conductive platen contacting the media transport belt; an electrostatic field reducer that includes an alternating current charge device positioned upstream of the one or more print heads; and one or apertures with electrically isolated biased electrodes separated by an opening that is in registration with the ink deposition areas of the one or more print heads. The media transport includes a media transport belt and, when the media is on the transport belt it has an electrostatic field, which can cause printing defects. The electrostatic field reducer and electrodes reduce the electrostatic field on the surface of the media and thereby reduce printing defects.Type: GrantFiled: June 7, 2013Date of Patent: May 3, 2016Assignee: Xerox CorporationInventors: Gerald M. Fletcher, Johannes N. M. de Jong, Peter Knausdorf, Steven R. Moore, Ramesh S. Palghat
