Patent number: 7811017Abstract: A non-gated print media crossover for a printing system includes crossover pathways which intersect at a crossover junction. A control system controls arrival of sheets of print media at the crossover junction whereby a sheet conveyed on the first crossover pathway traverses the junction in an intersheet gap between sheets traversing the junction on the second crossover pathway. The printing system includes print media processing units, such as marking engines, paper sources, and output destinations, which are connected by a conveyor system incorporating the crossover.Type: GrantFiled: October 12, 2005Date of Patent: October 12, 2010Assignee: Xerox CorporationInventors: Stan Alan Spencer, Daniel W.

Patent number: 7421241Abstract: Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.Type: GrantFiled: October 10, 2006Date of Patent: September 2, 2008Assignee: Xerox CorporationInventors: Joannes N.

Patent number: 7272334Abstract: A method is provided for aligning images on media produced by one or more print engines in an integrated print system. The method includes printing a first pattern of first symbols on a first region of a print medium with a first print engine and printing a second pattern of second symbols on a second region of the print medium with at least a second print engine in a manner to superpose the second pattern on the first pattern. The method further includes measuring a first deviation of the second pattern of second symbols relative to the first pattern of first symbols, recording the first deviation as a first offset distance relative to the first print engine, reporting the first offset distance to a controller of the second print engine, and, using the first offset distance for aligning at least the second print engine relative to the first print engine.Type: GrantFiled: March 31, 2005Date of Patent: September 18, 2007Assignee: Xerox CorporationInventors: Steven R.

Patent number: 6687479Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.Type: GrantFiled: May 31, 2002Date of Patent: February 3, 2004Assignee: Xerox CorporationInventors: Gerardo Leute, John W.

Patent number: 6661989Abstract: In a fusing apparatus, such as used in xerography, two rolls form a nip therebetween. A guide member is positionable to direct a sheet approaching the nip to enter the nip at an angle so that an arc or buckle is created in the sheet between a marking station and the nip. The arc or buckle is helpful in avoiding the transfer of mechanical energy from the fusing apparatus to the marking station. As the trailing edge of the sheet exits the marking station, the guide member is positioned to straighten the sheet.Type: GrantFiled: April 9, 2002Date of Patent: December 9, 2003Assignee: Xerox CorporationInventors: Ian Pitts, Stan Alan Spencer

Patent number: 6363238Abstract: A fluid sealing device for sealing liquid within a conditioning system wherein the liquid is supplied through a fluid supply hose to a fluid reservoir defined by the area of contact between a transfer roll and a metering device which controls the amount of fluid supplied to the transfer roll. The sealing device includes a nozzle positioned at an end of the fluid reservoir to generate a first pressure at the end of the fluid reservoir.Type: GrantFiled: March 16, 2001Date of Patent: March 26, 2002Assignee: Xerox CorporationInventors: Stan Alan Spencer, Jack G.

Patent number: 6282403Abstract: The present invention is useful in a nip-forming apparatus including a first roll and a second roll, wherein one of the rolls is displaceable toward the other to control the position of the first roll relative to the second roll, and wherein one of rolls is driven and the other is rotatable. The invention defines a setup procedure that includes rotating the driven roll and sensing a rotational speed of the rotatable roll. While the driven roll is rotating, the displaceable roll is displaced to a home displacement position relative to the other roll, wherein the home displacement position corresponds to a displaced position of the displaceable roll where the rotatable roll rotates at a select speed in response to contact with the driven roll. This home displacement position is then recorded. The invention is particularly well-suited for setup of a sheet decurler in an image forming apparatus. Change in the home displacement position over time due to roll wear is monitored and used to predict roll failure.Type: GrantFiled: May 2, 2000Date of Patent: August 28, 2001Assignee: Xerox CorporationInventors: Stan Alan Spencer, Jack G.

Patent number: 5720478Abstract: A device for inverting a sheet along a path in an electric photographic printing machine. A gateless sheet inverter is provided in which a curved portion of a sheet path branch intersects a second portion of the sheet path to form a curved inverter throat. As the sheet is driven from the curved branch portion of the path into the throat portion the beam strength of the sheet causes the trail edge of the sheet to flip toward a second nip leading to the second sheet path. A pair of reversing rolls captures the lead edge of the sheet to be inverted and then reverses to drive the sheets out of the second nip formed by a tri-roll arrangement. A sheet having a radius of curvature equal to or greater than the radius of curvature of the throat will be guided along the throat baffle and fed through the second nip. To further assist in assuring the trail edge flips to the second sheet path an air knife can be added at the intersection of the path branches to assist in moving the trail edge into the second path branch.Type: GrantFiled: September 26, 1996Date of Patent: February 24, 1998Assignee: Xerox CorporationInventors: Daniel L. Carter, Stan Alan Spencer, Carl B. Lewis, David M. Attridge
