Publication number: 20110193336Abstract: A scratch-off document may include a substrate bearing a toner image and a scratch-off layer covering the printed content. The scratch-off layer may include a mass of a first solid ink and a mass of a second solid ink printed over the first solid ink in a distraction pattern. The toner image is formed of a toner that adheres to the substrate, while the scratch-off layer is made of a wax-based or other solid ink that may be removed from the substrate by scratching without removing the toner image. The distraction pattern includes varying pile heights that distract a viewer from any pile height variations that may exist in the toner image.Type: ApplicationFiled: February 9, 2010Publication date: August 11, 2011Applicant: Xerox CorporationInventors: Reiner Eschbach, David A. Mantell, Paul J. McConville, Jason O'Neil, Trevor J. Snyder

Patent number: 7926898Abstract: A method of operating a printer turns off a support structure heater when the printer enters standby mode. The print head is then moved away from an intermediate transfer surface supported by a support structure. Heat settings used to heat a print head are then varied to heat the print head and the support structure. Another method of operating a printer turns off a support structure heater when the printer enters standby mode and holds a print head adjacent to an intermediate transfer surface while the printer is in standby mode.Type: GrantFiled: May 15, 2009Date of Patent: April 19, 2011Assignee: Xerox CorporationInventors: Trevor J.

Patent number: 7588305Abstract: A dual-drop mode for a printer uses at least two full length waveforms and switches between the waveforms according to one or more patterning methodologies to print a page length document having a dual drop size print pattern across the printed portion of the page. This achieves printing from individual jet nozzles of either a large drop or a small drop. The page size patterning methodology is performed globally on at least a sub-page basis, rather than on a pixel-by-pixel basis and may be performed based on or independent of specific image data.Type: GrantFiled: May 31, 2005Date of Patent: September 15, 2009Assignee: Xerox CorporationInventors: David L.

Patent number: 7401877Abstract: The embodiments provide a printer and a printing method that incorporate a printing mode capable of achieving high monochromatic quality at a low cost per page. This printing mode prints both fully saturated (or only minimally desaturated) monochrome images (e.g., black text and graphics) with no undercolor and significantly desaturated multi-color images on the same print medium. Optionally, the printing mode uses a specified resolution that is less than the maximum resolution, but greater than the minimum resolution. The printing mode also optionally prints outlines around monochrome images and/or color images in order maintain and enhance image quality.Type: GrantFiled: September 22, 2006Date of Patent: July 22, 2008Assignee: Xerox CorporationInventors: James B.
