Patent number: 10345705Abstract: Methods herein form a photoresist on an exterior of a cylinder and expose the photoresist to a light source while rotating the cylinder. Such methods develop the photoresist, after exposing, to change the photoresist into a patterned protective layer on the exterior of the cylinder. Then, these methods pattern the exterior of the cylinder while rotating the cylinder using the patterned protective layer to produce a patterned cylinder.Type: GrantFiled: July 12, 2013Date of Patent: July 9, 2019Assignee: Xerox CorporationInventors: Karl E. Kurz, Amir Prizant, Christopher D. Blair

Patent number: 10319415Abstract: A grid connector for communicating with a printed memory includes a substrate and a plurality of first conductive pads coupled to the substrate. Each of the first conductive pads protrudes outward with respect to an outer surface of the substrate. A subset of the first conductive pads is configured to contact a second conductive pad of the printed memory, regardless of an orientation of the printed memory with respect to the grid connector as long as the second conductive pad is within a boundary of the first conductive pads.Type: GrantFiled: April 26, 2017Date of Patent: June 11, 2019Assignee: XEROX CORPORATIONInventors: Michael A. Doody, Karl E. Kurz

Publication number: 20190025752Abstract: An exemplary grounding device includes an electrically conductive planar member having a hollow, central opening. Arms extend from inner edges of the hollow, central opening of the planar member. Each arm is angled relative to a surface of the planar member and each arm includes a facing portion having an electrically conductive cushion attached thereto. Each arm is approximately the same size and is configured to contact a shaft extending through the hollow, central opening of the planar member to form an electrical connection between the planar member and the shaft. The electrically conductive cushion is between the arm and the shaft. A tab projection extends from an outer edge of the planar member. Each tab projection is in the same plane as the planar member.Type: ApplicationFiled: July 18, 2017Publication date: January 24, 2019Applicant: XEROX CORPORATIONInventors: JONATHAN D. SADIK, NANCY L.

Patent number: 10175631Abstract: A ground plate includes an electrically conductive planar member having a long axis and a perpendicular short axis. The planar member has an elongated hexagonal shape having two opposing long sides, two opposing relatively shorter sides, and four angled sides between the long sides and the relatively shorter sides with a hollow central opening. Spring clips extend from inner edges of the hollow central opening. The inner edges from which the spring clips extend are parallel to the long axis. Each spring clip includes a distal end portion curving outward from the hollow central opening and is configured to contact a shaft extending through the hollow central opening to form an electrical connection between the planar member and the shaft. A tab projection extends from an outer edge of each of the relatively shorter sides. Each tab projection is in the same plane as the planar member.Type: GrantFiled: May 10, 2017Date of Patent: January 8, 2019Assignee: Xerox CorporationInventors: Jonathan D. Sadik, Karl E.

Patent number: 7949268Abstract: A xerographic marking engine adjusts a charging actuator value, such as an AC peak-to-peak voltage or an AC peak-to-peak current, based on a determined knee value, VKNEE, of a charge curve for an imaging apparatus photoreceptor within the xerographic marking engine and environmental sensor data. The environmental sensor data may measure environment temperature and environment humidity. In near A-zone environments, for example, operational environments in which the temperature is 80 degrees Fahrenheit and the relative humidity is 80%, the charging actuator value may be selected to achieve a predetermined photoreceptor wear rate that avoids print quality defects due to lateral charge migration. In other than A-zone environments, the charging actuator value may be selected to minimize the photoreceptor wear rate, while avoiding print quality defects. The described approach allows optimal photoconductor wear to be achieved, in all operational environments, without increasing the risk of print quality defects.Type: GrantFiled: October 2, 2008Date of Patent: May 24, 2011Assignee: Xerox CorporationInventors: Aaron Michael Burry, Kenny-tuan T. Dinh, Karl E. Kurz, Bruce E. Thayer, Michael F. Zona

Patent number: 7756442Abstract: A guide is used to protect a corona cartridge during shipping and during insertion into an electrostatic marking apparatus. The guide has dimensions that will permit the cartridge to fit therein and has a locking mechanism that securely holds the cartridge in place during shipment or movement. When the cartridge is to be removed from the guide and inserted into an electrostatic marking system, a handle attached to a latch is used to free the latch from a groove in the guide. The groove in the guide is located between two upwardly protruding ramps having a slidable side and a locking side that abuts the latch and holds it in place until activation when the latch handle frees it from the groove.Type: GrantFiled: September 18, 2006Date of Patent: July 13, 2010Assignee: Xerox CorporationInventors: David L. Keefe, Karl E. Kurz, Mark T. Bartlett

In near A-zone [80 degrees Fahrenheit and 80 percent relative humidity] environments, the charging actuator value may be selected to achieve a predetermined photoreceptor wear rate that avoids print quality defects due to lateral charge migration. In other than A-zone environments, the charging actuator value may be selected to minimize the photoreceptor wear rate, while avoiding print quality defects.
