Patent number: 9272864Abstract: A sheet jam access assembly in combination with a finisher transport assembly having a main transport cover, is used with a digital printer. First and second axles with idler nip rollers are mounted on the transport assembly for movement away from the process path. First and second drive nip rollers are mounted for driven rotation on the transport assembly. A jam access cover pivots on the main transport cover from a closed to an open position. First and second hinges each have a first outer leaf on the jam access cover connected by a hinge pin to an inner leaf which translates transverse to the process direction. The hinge axis is spaced apart from the cover axis. A cam plate base portion translates parallel to the process direction. First and second ramps adjacent the axles extend away from the base portion at an angle to the process direction. A slot extends through the first inner leaf at an angle to the process direction.Type: GrantFiled: June 5, 2014Date of Patent: March 1, 2016Assignee: XEROX CORPORATIONInventors: Ron Edward Dufort, Arthur Harold Kahn, Brian Roy Ford

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: 8923616Abstract: Embodiments described herein include an image-content dependent system for cutting a print in response to content of an image disposed on the print. The system includes a print cutter, a computer storage device, and a processing device. The print cutter cuts a print according to an image-content dependent cut pattern. The computer storage device stores image component metadata created from image content of an image disposed on the print to be cut. The processing device uses the image component metadata to generate the image-content dependent cut pattern to be used by the print cutter to cut the print.Type: GrantFiled: July 29, 2011Date of Patent: December 30, 2014Assignee: Xerox CoporationInventor: Ron Edward Dufort

Publication number: 20110148026Abstract: A guiding system for diverting media from an input media path to an output media path in an imaging system eliminates marking and curling of media. The system employs a drive roll, an idling belt carried on one or more idler rolls, and a release roll. The idling belt presses media onto the drive roll, eliminating the relative motion between media and the drive roll and hence avoiding marking. The penetration of the release roll into the drive roll controls curling of media.Type: ApplicationFiled: December 23, 2009Publication date: June 23, 2011Applicant: XEROX CORPORATIONInventor: RON EDWARD DUFORT
