Abstract: Printers and cleaning systems are provided. A cleaning system has an actuator that moves the electrostatic imaging member in a second direction opposite the first direction and a frame positions a mounting within a first range of mounting distances from the electrostatic imaging member with the mounting holding a cleaning blade at a holding angle that causes a free length of the cleaning blade to extend along a first direction to position a cleaning end of the cleaning blade to engage the electrostatic imaging member for movement therewith. The electrostatic imaging member urges the cleaning end in the second direction to deflect the cleaning blade to extend along the second direction to position the cleaning end to wipe the electrostatic imaging member and the free length, the holding angle and the working angle cause the cleaning edge to wipe at a working angle between about 85 and 89 degrees.

Abstract: A cleaning system has a composite photoreceptive imaging member having a support layer, an electrically conductive layer interfacing with the support layer, a photoconductive charge generation layer interfacing with the electrically conductive layer and generating charge holes and electrons in response to exposure to electromagnetic radiation; a charge transport layer that allows charge holes to migrate from the charge generation layer to the outer surface while resisting migration of electrons from the charge generation layer to the outer surface and a cleaning blade member having a cleaning surface layer against the electrostatic surface to at least in part remove toner and debris from the outer surface. The cleaning surface layer has a first material and a second material that are combined in proportions that cause a triboelectric charge to be formed on the outer surface having a difference of potential of between zero and minus 20 volts.

Abstract: Electrophotographic printers and cleaning systems for an electrostatic imaging member are provided. In one aspect the cleaning system has a scraper a mounting holding the scraper so that a free length of the scraper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the scraper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the free length with the scraper resiliently deflecting to fit within the extension distance to define a working angle where the scraper contacts the electrostatic imaging member.

Abstract: Cleaning systems for an electrostatic imaging member and printers having cleaning systems are provided. In one aspect, a cleaning system has a wiper, a mounting holding the wiper so that an extension length of the wiper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the wiper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the extension length with the wiper resiliently bending to fit within the extension distance to define a working angle. The extension distance is within a range of extension distances that cause the working angle to be within a range of working angles that are greater than a range of working angles associated with a greater range of extension distances.

Abstract: A web cleaning device for cleaning contaminants from a moving surface in a printer apparatus. The cleaning device includes a nesting structure having a longitudinally extending internal surface for supporting a coil of a web fabric extending in a longitudinal direction and an external surface located opposite to the internal surface. A lip member forms a part of the nesting structure and is located adjacent a pay out end of the coil. The pay out end of the coil is wrapped about the lip member and further wrapped about the external surface of the nesting structure. The web fabric is also wound about a take-up spindle that is spaced from the coil. A portion of the web fabric from the pay out end of the coil to the external surface of the nesting structure provides a hairpin type curvature to the path of the web fabric to reduce tendency of the web fabric to bind during pay out of the web fabric from the pay out end of the coil.

Abstract: In a method and apparatus for transferring a toner image to a receiver sheet, there is provided an endless belt that is mounted for movement in a direction along a lengthwise dimension of the belt and through an endless path. The belt includes a splice seam that occurs transverse to the direction of movement of the belt, the seam having a discontinuity into which toner tends to collect which is free to transfer. The seam includes a bump proximate each end of the splice seam which extends above the seam. A rotatable member rotates while in engagement with a surface of the belt so as to urge a receiving sheet into intimate engagement with the surface between the rotatable member and the belt. The bumps support the rotatable member out of engagement with the splice seam to substantially preclude transfer to the rotatable member of toner accumulating in the splice seam between the bumps.

Abstract: A mechanism for cleaning the back side of an image bearing dielectric support web used in an electrostatographic reproduction apparatus, the dielectric support web, having a front side movable into operative association with a plurality of electrographic processing stations to form a transferable marking particle image thereon. The back side cleaning mechanism have a catch tray for collecting debris removed from the back side of the dielectric support web. A cleaning blade is attached to the catch tray so as to engage the back side of the dielectric support web at a predetermined angle to wipe such back side thereof. A magnetic scavenger is attached to the catch tray, in spaced relation with the cleaning blade, so as to remove magnetic particles from the back side of the dielectric support web.
