    摘要： 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.

    摘要： 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.

    摘要： A cleaning apparatus having a spots cleaning blade to remove residual agglomerations of particles from the imaging surface. The spots cleaning blade is made from a material that has a low coefficient of friction, low resilience and higher hardness than a standard spots blade. These properties enable the spots cleaning blade to provide a continuous slidable contact with the imaging surface to remove residual particles therefrom. Additionally, an electrically conductive surface can be added to the front or back surface of the blade to cause toner particles to be repelled from and cloud near the blade where they can be removed by a vacuum device or the like. The conductive surface may be direct negative, direct positive or A-C potential to provide the necessary repelling force.
