  • Publication number: 20180032003
    Abstract: A method and system for reducing contamination build-up within a fuser roll system are disclosed where there is provided the positioning of an active static eliminator over the pre-fuser transport. This device will neutralize the charge on the surface of the toner after transfer/detack thereby reducing the attraction to the surface of the fuser roll which is conductive and grounded.

  • Patent number: 7344809
    Abstract: An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.

  • Patent number: 7218886
    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.

  • Patent number: 7085512
    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.

  • Patent number: 7005222
    Abstract: An imaging member having a charge transport layer with multiple regions is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein at least the top or uppermost transport layer comprises a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be of the same or different compounds from that included in the top or additional charge transport layer(s). The charge transport compound present in each layer may be dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
