Patent number: 8184995Abstract: A diagnostic system made part of or for use with a document handling device in which a customer is guided toward performance of at least one comparison means in a diagnostic routine analysis. The comparison means is selected from a group comprising (1) a first comparison comparing a fused print media and an unfused print media for presence of a defect, (2) a second comparison comparing an output print media and at least one image on a screen for a type of defect, and (3) a third comparison comparing a low-charged print media and a no-charged print media for qualities of the defect. The customer enters a selection based on results of the first, the second, or the third comparisons. The diagnostic system can identify a part causing a defect in the print media based on results of the comparisons.Type: GrantFiled: May 27, 2009Date of Patent: May 22, 2012Assignee: Xerox CorporationInventors: Michael Nicholas Soures, James Joseph Petery, Timothy D.

Patent number: 8103206Abstract: Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor, the position of the lubrication stripe is controlled with respect to a position on the main surface of the charge receptor corresponding to a paper trail edge. The dimensions and density of the lubrication stripe may also be controlled. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade.Type: GrantFiled: August 20, 2008Date of Patent: January 24, 2012Assignee: Xerox CorporationInventors: Robert Arnold Gross, Michael Nicholas Soures, Robert Steven Pozniakas

Patent number: 8023852Abstract: Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of at least one corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the at least one corotron.

A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of a pre-clean corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the pre-clean corotron. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade.Type: GrantFiled: August 20, 2008Date of Patent: May 17, 2011Assignee: Xerox CorporationInventors: Robert Arnold Gross, Michael Nicholas Soures, Robert Steven Pozniakas

Publication number: 20100046976Abstract: Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time.
