Patent number: 9075363Abstract: An approach is provided for reducing release agent transfer to a pressure member in a fuser. The approach involves causing, at least in part, at least a first sheeted substrate and a second sheeted substrate to be advanced through a fuser in a process direction. The approach also involves determining the presence of the first sheeted substrate at a fusing position. The approach further involves causing, at least in part, a fuser member and a pressure member to engage to form a fusing nip at the fusing position based, at least in part, on the determined presence of the first sheeted substrate at the fusing position. The approach additionally involves determining the first sheeted substrate has advanced through the fusing nip. The approach further involves causing, at least in part, the fuser member and the pressure member to disengage.Type: GrantFiled: June 15, 2012Date of Patent: July 7, 2015Assignee: Xerox CorporationInventors: Melissa Ann Monahan, Erwin Ruiz, Steven Russel, Jeffrey Nyyssonen Swing, Christopher Alan Jensen

Patent number: 9063479Abstract: A system and method are provided to implement a double belt roll fuser geometry to enable consistent self-stripping of image receiving media exiting a fuser assembly in an image forming device. Interaction between an image receiving medium substrate and a fuser belt of a belt roll fuser device is modified to include configuration in which an opposing belt is positioned around a pressure roller to oppose the fuser belt provided around the fuser roller. The fuser belt and the opposing belt extend in a downstream direction from the fusing nip and are configured to provide an appropriate length downstream of the fusing nip that sandwiches the image receiving medium substrate between the fuser belt and the opposing belt. Each of the fuser belt and the opposing belt wrap 70 degrees or more around significantly smaller diameter rollers positioned downstream of the fusing nip to form a stripping nip.Type: GrantFiled: February 19, 2013Date of Patent: June 23, 2015Assignee: Xerox CorporationInventors: Christopher Alan Jensen, Steven Matthew Russel, David P.

Patent number: 8913912Abstract: An approach is provided for applying a release agent to a substrate having at least a first surface and a second surface. The approach involves determining a print job type for applying one or more printed images to the substrate to be one of a simplex print job type that applies the one or more printed images to one of the first surface and the second surface and a duplex print job type that applies the one or more printed images to the first surface and the second surface. The approach also involves processing the determined print job type to cause, at least in part, a determination of a release agent application instruction that corresponds with the determined print job type. The approach further involves causing, at least in part, an amount of the release agent to be applied to the substrate based on the release agent application instruction.Type: GrantFiled: June 15, 2012Date of Patent: December 16, 2014Assignee: Xerox CorporationInventors: Melissa Ann Monahan, Erwin Ruiz, Steven Russel, Jeffrey Nyyssonen Swing, Christopher Alan Jensen

Patent number: 8832896Abstract: A paint roller apparatus is provided. In one example, the paint roller apparatus is configured to apply paint to a surface and includes a roller arm and a paint roller rotatably mounted on the roller arm about a roller axis. The paint roller has an end and a paint applicator surface. The paint roller apparatus includes a roller guard having at least one painting feature for applying paint to the surface. The roller guard is selectively movable between first and second positions. The first position comprises the painting feature disposed adjacent the end of the roller on a first side of the roller axis and the second position comprises the painting feature disposed adjacent the end of the roller on a second side of the roller axis.Type: GrantFiled: May 2, 2012Date of Patent: September 16, 2014Assignee: Wagner Spray Tech CorporationInventors: Jeffrey E. Sandahl, Jeffrey Mark Smith, Christopher Alan Jensen, Thomas Rainer Jeltsch

Patent number: 8768230Abstract: An approach is provided for reusing a cleaning web to clean portions of a fuser unit. The approach involves causing a cleaning web supply mechanism to feed a cleaning web having a first surface and a second surface to the portions of the fuser unit. The approach also involves causing a cleaning web receiving mechanism to receive the cleaning web following a cleaning process in which the first surface of the cleaning web is used to clean at least one of the portions of the fuser unit. The approach further involves causing the cleaning web receiving mechanism to return the cleaning web to the portions of the fuser unit to clean at least one of the portions of the fuser unit using the second surface of the cleaning web.Type: GrantFiled: June 15, 2012Date of Patent: July 1, 2014Assignee: Xerox CorporationInventors: Jeffrey Nyyssonen Swing, Christopher Alan Jensen, Melissa Ann Monahan, Erwin Ruiz, Steven Russel

METHOD AN APPARATUS FOR SELECTIVELY LOADING A CLEANING WEB IN A FUSER UNIT BASED ON MEDIA ATTRIBUTES
Publication number: 20130343773Abstract: An approach is provided for selectively loading a cleaning web useful in printing based on various media attributes of a media that is to be processed by a fuser unit. The approach involves determining one or more media attributes associated with a media to be processed by a fuser unit, the fuser unit comprising one or more heat rolls. The approach also involves determining at least one of the one or more media attributes meets a predetermined criteria. The approach further involves causing, at least in part, a cleaning web to contact at least one of the one or more heat rolls based, at least in part, on the determination that one or more media attributes meets the predetermined criteria.Type: ApplicationFiled: June 21, 2012Publication date: December 26, 2013Applicant: XEROX CORPORATIONInventors: Melissa Ann MONAHAN, Erwin RUIZ, Steven RUSSEL, Jeffrey Nyyssonen SWING, Christopher Alan JENSEN -
