Abstract: Methods for texturing the surface of photoreceptors are provided.

Abstract: Embodiments herein comprise a charging station adjacent a photoreceptor. The charging station is adapted to charge the document zone of the photoreceptor with a first negative voltage and to charge the inter-document zone of the photoreceptor with a second negative voltage that is more negative than the first negative voltage. The second more negative voltage reduces the amount of positive charges trapped within layers of the inter-document zone of the photoreceptor. Thus, when the charging station increases the size of the document zone from a smaller size associated with a smaller printing medium to a larger size associated with a larger printing medium, by reducing the positive charges from being trapped within layers of the inter-document zone of the photoreceptor, ghosting is reduced on the larger printing medium.

Abstract: A method for fabricating an abrading brush comprising: providing brush includes a core defining a core length and having fibers extending outwardly therefrom; applying an epoxy binder on the fiber; and spray coating a layer of abrasive particles on the ends of the fibers.

Abstract: A cleaning system including: a cleaning device for cleaning laterally conductive deposits from the imaging surface; an AC bias member, adjacent to the imaging surface and positioned downstream from the cleaning device; and a power supply for biasing the AC bias member to generate corona that contacts the imaging surface to degrade laterally conductive deposits that lead to lateral charge migration on the imaging surface.

Abstract: A cleaning system for cleaning an imaging surface moving in a process direction, including: an abrading brush for uniformly abrading the imaging surface to remove laterally conductive deposits that lead to lateral charge migration therefrom, the abrading brush includes a core defining a core length and having fibers extending outwardly therefrom, the fibers include abrasive particles attached thereto.

Abstract: Apparatus and methods reduce, and preferably prevent, contamination of a surface or component to be charged or acted upon by a corona generating device. When a voltage is applied to the corona generating device, corona winds having a plurality of corona vortices are formed. Air is pulled via at least one drawing port of the corona generating device. At least one substantially continuous air curtain is formed along a side of the corona generating device when air is pulled via the drawing port of the corona generating device. The formation of the continuous air curtain is not dependent on air being pushed into the corona generating device. Preferably the substantially continuous air curtain extends from substantially one end of the corona generating device, at least a distance equivalent to a greatest continuous total length of the plurality of corona vortices and any portion of the corona generating device situated therebetween.

Abstract: A method for removing a residue, such as lateral charge migration (LCM) film, from an imaging member includes contacting at least a portion of the imaging member with a wash liquid capable of removing the residue. The wash liquid containing the residue is then removed, for example, by applying an absorbent material such as a toner, to the contacted portion of the imaging member.

Abstract: Packaging apparatus is provided for packaging a flexible photoconductive belt loop to prevent light from shocking the flexible photoconductive belt loop during shipping and during loading into an image reproduction machine. The packaging apparatus includes (a) a cut sheet of light occluding and protective flexible member for wrapping over the flexible photoconductive belt loop. The cut sheet has a length L2 including a first end, a second end, and (iv) at least one loop tacking aperture formed through a second end portion thereof. The packaging apparatus also includes a first adhesive tape member applied over the second end portion, through the at least one loop tacking aperture, and onto a first end portion. The packaging apparatus further includes a plurality of packaging cores, and a second adhesive tape member applied over the second end and over a portion of the main body portion.

Abstract: A packaging machine and method are provided for wrapping, folding and taping a flexible photoconductive belt loop to prevent light from shocking such photoconductive belt loop during shipping and during loading into a machine.

Abstract: A light source within a photocopy machine continuously shines high level, wide band fluorescent light on the photoreceptor to maintain the photoreceptor in a uniformly light-shocked condition. This constant level of light shock has no adverse effects on either the life or performance of the photoreceptor in normal operation. Thus, the photoreceptor becomes less sensitive to unintentional, uneven ambient room light and random, long lasting delta voltages within the print area are reduced so that print quality defects are minimized.
