Patent number: 8032053Abstract: A latch apparatus has a latch base, a latch frame, and at least one flexible bracket connecting the latch frame to the latch base. Connectors are used to connect the flexible bracket to the latch frame and connect the flexible bracket to the latch base. The connectors prevent the outer surface of the flexible bracket from moving along the surface of the latch frame or the surface of the latch base. A biasing member is connected to the latch base and the latch frame. The flexible bracket maintains a gap between the latch base and the latch frame and prevents the latch base from contacting or sliding along the latch frame.Type: GrantFiled: May 29, 2008Date of Patent: October 4, 2011Assignee: Xerox CorporationInventors: Mark A.

Patent number: 8004551Abstract: In a color marking assembly, a series of ROS units are aligned above a photoconductive surface. These units have inboard and outboard mounts connecting them to this assembly. The inboard mounts are attached to a first side of the ROS, and the outboard mounts are attached to a second side of the ROS unit. The inboard mount is an elongated bar extending beyond the height of the ROS unit. This elongated bar has hinged portions on both its top and bottom connections to the ROS unit. The outboard mount has a ball bearing or sphere configuration. This configuration and the inboard mount enable the ROS unit to be easily deskewed when required.Type: GrantFiled: March 24, 2008Date of Patent: August 23, 2011Assignee: Xerox CorporationInventors: Mark A Atwood, Joseph M Wing, Brian J Perry, James P Calamita, Thomas R Race, Alan G Schlageter

Patent number: 7417662Abstract: A docking system may repeatedly dock a movable sensor module relative to another module with high precision. The docking system may move with minimal constraints and several degrees of freedom. The docking system may be particularly useful for precisely locating a movable sensor module relative to another module, such as a full width array sensor relative to a photoreceptor module within an image forming apparatus. A high degree of freedom may be achieved through use of a series of at least three spherical bearing connections that enable freedom of movement about X, Y and Z axes.Type: GrantFiled: September 12, 2006Date of Patent: August 26, 2008Assignee: Xerox CorporationInventors: Joseph M.

Patent number: 6804485Abstract: A photoconductive member for use in a single pass multi-color printing machine is disclosed. The photoconductive member is composed of an inter seam zone having a physical seam. The inter seam zone includes one of a plurality of image-on-image registration marks respective to a particular color latent image formed on the photoconductive member in a single pass. A plurality of interdocument zones is also included on the photoconductive member wherein process control marks are formed. While the inter seam zone is used for monitoring color-to-color registration, the process control marks are monitored to adjust the timing of the printing machine so that copy media synchronizes with an asynchronous placement of the images on the photoconductive member. A single pass, multi-color electrophotographic printing machine architecture uses a vertically oriented photoconductive belt. Transfer of the toner powder images occur at the lowermost portion of the photoconductive belt.Type: GrantFiled: October 22, 2002Date of Patent: October 12, 2004Assignee: Xerox CorporationInventors: Michael J. Martin, Joseph M. Wing, Mark A. Omelchenko

Publication number: 20020114641Abstract: A belt drive module and a corresponding method includes or employs a belt that moves along a path, at least one support roller or other structure that supports the belt as it moves along the path, a drive roller that effects movement of the belt along the path, a tension roller that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the belt, and a torque assist drive that applies a torque assist force Td at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller, e.g., a stripper roller of an electrophotographic imaging system.
