Abstract: In order to prevent built up crusts on the flicker assembly from being detrimentally dislodged due to the cleaning fibers impacting the flicker bar assembly, there is provided a soft contact portion flicker bar assembly for mounting in a machine to contact and flick the cleaning fibers moving along a fiber path. The soft contact portion flicker bar assembly includes (a) a base portion for mounting to a frame portion of the machine; (b) a body portion including a distal, first end, and an opposite, second end connected to the base portion; and (c) a tip portion connected to the first, distal end for contacting and interfering with cleaning fibers moving along the fiber path. The tip portion is made of a material having a Shore A durometer hardness of less than 85 for reducing a jarring effect of impact forces between such tip portion and the moving cleaning fibers, thereby preventing detrimental dislodging of built up crusts of particles from any part of the flicker bar assembly.

Abstract: There is disclosed a system for cleaning marking material from a surface portion of a movable photoconductive member. The system includes a first rotatable brush, a blade and a second rotatable brush arranged in sequential order along the movable photoconductive member. The first rotatable brush is for removing a first amount of marking material from the surface portion of the movable photoconductive member as the surface portion of the movable photoconductive member moves past said first rotatable electrostatic brush. The blade, in engaging contact with the movable photoconductive member, is for removing a second amount of marking material from the surface portion of the movable photoconductive member. The second rotatable brush, positioned in interference contact with the movable photoconductive member, is for removing substantially all residual marking material that was not removed by the first rotatable brush and the blade.

Abstract: A photoconductor belt cleaning system is described. This system can utilize in one embodiment one cleaning brush and a cleaning blade, and in a second embodiment, two cleaning brushes, brush 1 and brush 2, with a cleaning blade. In the second embodiment, the cleaning blade is located in the system before brush 2, and adjacent to brush 1. The brushes are charged in an opposite polarity to the charge of the toner to be removed from the photoconductor belt.

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: 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 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.
