Patent number: 11760028Abstract: A material drop ejecting three-dimensional (3D) object printer identifies a time lag error corresponding to a time lag in the response of printer components to component commands. The identified time lag error is provided to a slicer program that uses the identified time lag error to compensate for the time lag in the response of the printer components.Type: GrantFiled: January 30, 2021Date of Patent: September 19, 2023Assignee: Xerox CorporationInventors: Rachel L. Tanchak, Erwin Ruiz, Brendan McNamara, Piotr Sokolowski, Jack G. Elliot, Ka H. Fung, Derek A. Bryl, Douglas E. Proctor, Christopher T. Chungbin, Peter M. Gulvin

Patent number: 11701712Abstract: A slicer in a material drop ejecting three-dimensional (3D) object printer generates machine ready instructions that operate components of a printer, such as actuators and an ejector having at least one nozzle, to form features of an object more precisely than previously known. The instructions generated by the slicer control the actuators to move the ejector and a platform on which the object is formed relative to one another at a constant velocity to form edges of the feature.Type: GrantFiled: January 30, 2021Date of Patent: July 18, 2023Assignee: Xerox CorporationInventors: Jack G. Elliot, Rachel L. Tanchak, Derek A. Bryl, Piotr Sokolowski, Erwin Ruiz, David A. Mantell, Brendan McNamara, Peter M. Gulvin, Christopher T. Chungbin

Patent number: 10239328Abstract: A printing system facilitates the printing of articles of manufacture. The system includes an array of printheads, a support member positioned to be parallel to a plane formed by the array of printheads, a member movably mounted to the support member, an actuator operatively connected to the movably mounted member, an object holder configured to mount to the movably mounted member, and a controller operatively connected to the plurality of printheads and the actuator. The controller is configured to operate the actuator to move the object holder past the array of printheads and to operate the plurality of printheads to eject marking material onto objects held by the object holder as the object holder passes the array of printheads. The support member and printhead array are oriented vertically to enable the printing system to be installed in a vertical cabinet that provides a small footprint in a non-production environment.Type: GrantFiled: September 14, 2017Date of Patent: March 26, 2019Assignee: Xerox CorporationInventors: Wayne A. Buchar, James J. Spence, Jack G. Elliot, Michael F. Leo

Patent number: 7731188Abstract: A sheet handling system comprising a sheet registration system having sheet registration nips and a receiving system for a sheet including a capturing point for engaging said sheet. Auxiliary nips are positioned between the sheet registration nips and the receiving station. The auxiliary nips are moveable between an open and closed position. A controller receives a signal indicative of the length of the sheet and sends a signal to the auxiliary nips to be in a sheet engaging position when the length of the sheet is less than the distance between the sheet feeding nips and the capturing point of the receiving station and be in an open position if the length of the sheet is greater than the distance between the sheet registration nips and the capturing point of the receiving station. In another embodiment, the auxiliary nips are maintained in their open position until the trailing edge of a sheet is about to leave the sheet registration nips, at which point the auxiliary nips are closed.Type: GrantFiled: July 18, 2007Date of Patent: June 8, 2010Assignee: Xerox CorporationInventors: Joannes N. M. deJong, Lloyd A. Williams, Jack G. Elliot

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. Elliot, Leonid Buchman

Patent number: 6011947Abstract: A device and method for automatically adjusting conditioner metering roll liquid film thickness. The device including a transfer roll that mates with a back-up roll to form a nip through which a sheet passes for wetting a side of the sheet. A metering roll mates with the transfer roll and has a portion thereof positioned in a liquid filled sump for liquid to be added to an outside surface thereof. An optical sensor is positioned to detect the type of reflected light from the liquid on the outside surface of the metering roll and gives off a signal that is received by a controller that actuates a stepper motor to move the metering roll in a predetermined direction until the correct liquid thickness is obtained on the surface of the metering roll.Type: GrantFiled: September 29, 1997Date of Patent: January 4, 2000Assignee: Xerox CorporationInventors: Thomas Acquaviva, Jack G.
