Patent number: 9073259Abstract: Embodiments described herein are directed to generating physical three-dimensional color-accurate objects based on a 3D computer-based color model using printed layers of media. Embodiments can slice a 3D computer-based color model into 3D cross-sectional components, which retain the color information of the model. The 3D cross-sectional segments can be converted into 2D page images and the color information can be included in a plan image corresponding to the cross-sectional segments. Embodiments can print the page images to form cross-sectional prints which can be layered and trimmed to shape the prints into a color accurate physical object that represents the model.Type: GrantFiled: November 29, 2011Date of Patent: July 7, 2015Assignee: Xerox CorporationInventors: Ron Edward Dufort, Frank Albert Porter, Venkata Bharadwaj Chivukula, Aaron Michael Moore, Adam Douglas Ledgerwood

Patent number: 8708337Abstract: Provided herein is sheet inverter apparatus which includes a diverter gate which diverts the sheet to one of at least two paths, a first paper path, and a second paper path. The first and second path each include a rotatable nip assembly, the rotatable nip assembly including a nip drive roll and a nip idler roll positioned so as to define a nip therebetween, the nip serving as a rotatable axis around which the nip drive roll and the nip idler roll rotate to invert the sheet.Type: GrantFiled: September 28, 2012Date of Patent: April 29, 2014Assignee: Xerox CorporationInventors: Bruce Allen Thompson, Frank Albert Porter, Michael J. Linder, William Matthew Harney, Robert Rinefierd

Patent number: 8579281Abstract: A sheet inverter apparatus improves the handling capabilities of high speed printers and copiers. The sheet inverter apparatus includes a rotatable support having an axis of rotation and at least first and second arms radiating outwardly from the axis of rotation. First and second nip assemblies are is mounted to the first and second arms respectively. The support is rotatable to adjust positions of the first and second nips about the axis of rotation. Advantageously, with this arrangement, the support is adjustable so as to permit the first and second nips to receive sheets of paper at one location, be positionally adjusted with the sheets of paper moving therewith, and located at a second location so as to deliver the paper to an outlet feed path. This positional adjustment allows for inversion of the paper.Type: GrantFiled: October 17, 2012Date of Patent: November 12, 2013Assignee: Xerox CorporationInventors: Bruce Allen Thompson, Frank Albert Porter, Michael J. Linder, William Matthew Harney, Robert Rinefierd

Patent number: 8538306Abstract: An apparatus includes a photoreceptor belt, a fixed transfer roller positioned on the inside of the photoreceptor belt, and a movable transfer roller positioned on the outside of the photoreceptor belt. The fixed transfer roller and the movable transfer roller are positioned to form a nip, and the photoreceptor belt and a web of print media are positioned in the nip. Also, a support roller and a compensation roller contact the web of print media. The support roller is positioned between the compensation roller and the nip. A physical link is connected to the support roller and the compensation roller. The physical link moves the support roller and the compensation roller so as to keep a constant tension on the web of print media.Type: GrantFiled: May 23, 2011Date of Patent: September 17, 2013Assignee: Xerox CorporationInventors: Ming Yang, Roger G. Leighton, Frank Albert Porter, Carlos Manuel Terrero

Patent number: 8494412Abstract: Systems and a method for image forming systems to skip over the non-printing photoreceptor area in order to not skip a label position on a continuous print web medium. A vacuum assembly is coupled to a controller that controls different vacuum pressures at each vacuum roller therein. The vacuum rollers provide drag and drive forces to skip a seam of the photoreceptor and a residual length based on the number and size of images on the photoreceptor.Type: GrantFiled: March 28, 2011Date of Patent: July 23, 2013Assignee: Xerox CorporationInventors: Kenneth Paul Moore, Frank Albert Porter, Bruce Allen Thompson, Todd Maurice Uthman, Ron Edward Dufort, Venkata Bharadwaj Chivukula, Roger Gaylord Leighton

Patent number: 8459644Abstract: A dual path, single reversing roll inverter driven by a single actuator includes a single reversing roller with two, diametrically opposed idler rollers. The configuration of the reversing roller and idler rollers forms a first nip and a second nip that are alternately used to accept sequential sheets from a paper path. The first and second nips discharge the sheets into respective first and second inverting paths. A method for inverting sheets using the dual path, single reversing roll inverter includes rotating the roller in a first direction to direct a first sheet through the first nip. The roller is then rotated in a second direction opposite the first direction to direct the first sheet from the first nip and into the first inverting path and to simultaneously direct a second sheet into the second nip. A gate alternately directs the sequential sheets into the first and second nips.Type: GrantFiled: April 10, 2012Date of Patent: June 11, 2013Assignee: Xerox CorporationInventors: Bruce Allen Thompson, Frank Albert Porter, Michael J.
