Publication number: 20100276873Abstract: Systems for moving a moveable drive module in a cross-process direction are disclosed. A system includes a moveable drive module and a cross-process positioning system. The moveable drive module includes a drive roll. The cross-positioning system is capable of moving the moveable drive module in a cross-process direction. The system may optionally include a plurality of idler rolls, each configured to be associated with the drive roll when the moveable drive module is in an associated position.

Patent number: 7647018Abstract: A printing system and method is provided. The printing system includes one or more printing system modules, at least one media sheet path interfacing the printing system modules, and a job scheduler for executing one or more printing system print jobs. The job scheduler routes a media sheet to one or more printing system modules for preshrinking or preenlarging without marking and subsequently routes the preshrunk or preenlarged media sheet to one or more printing system modules for marking. The method of printing includes generating a print job to be printed using one or more printing system modules. Print jobs requiring two or more printing system modules for marking are executed by routing a media sheet to one or more printing system modules for preshrinking or preenlarging without marking, and subsequently routing the preshrunk or preenlarged media sheet to the one or more printing modules for marking.Type: GrantFiled: July 26, 2005Date of Patent: January 12, 2010Assignee: Xerox CorporationInventors: Steven R. Moore, Joannes N. M. de Jong, Matthew Dondiego, Vittorio Castelli, Lloyd A. Williams

Publication number: 20090302145Abstract: A web system, such as a printing web system, having reduced power consumption is disclosed. Power consumption is reduced by joining the unwind and rewind shafts of the web system together through a continuously variable transmission (CVT). The CVT allows the unwind and rewind rolls to provide torque to each other as well, allowing fewer drive motors and/or drive motors of smaller size to be used in the web system.Type: ApplicationFiled: June 10, 2008Publication date: December 10, 2009Applicant: Xerox CorporationInventors: Joannes N. M. deJong, Lloyd A. Williams, Matthew Dondiego

Patent number: 7126621Abstract: An imaging device for producing multicolor images from image data containing data representing an image of a first color and an image of a second color to be registered relative to the image of the first color onto a substrate by transferring toner of the first and second colors to the substrate is provided. The imaging device includes a first imager, a second imager, a photoreceptor belt, a plurality of rollers mounted to a frame of the imaging device, an angular position sensor, an image data source and a controller. The plurality of rollers define a process path along which the photoreceptor belt is driven past the first and second imagers in a process direction. The plurality of rollers includes a drive roller that exhibits an eccentricity for which a formula relating angular position as a function of the phase angle of the drive roller to eccentricity is known. The angular position sensor detects the phase angle of the drive roller.Type: GrantFiled: July 30, 2004Date of Patent: October 24, 2006Assignee: Xerox CorporationInventors: Vittorio Castelli, Joannes N. M. deJong, Lloyd A. Williams, Matthew Dondiego, William J. Nowak

Patent number: 6866260Abstract: A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a lower power, lower mass, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.Type: GrantFiled: February 19, 2003Date of Patent: March 15, 2005Assignee: Xerox CorporationInventors: Lloyd A.
