摘要： A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method includes the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit including a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further includes contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.

摘要： A method and apparatus of the invention includes a method of removing airborne hydrocarbons from liquid electrophotographic printer exhaust comprises generating airborne hydrocarbon droplets as either vapor or mist during the transportation of electrophotographic ink or toner, directing substantially all of the air and hydrocarbon droplet mixture to a central collection point, forcing the air/droplet mixture to and through an oleophilic, substantially non-leaching collection media, and exhausting substantially hydrocarbon-free air from the electrophotographic printer. The method may further comprise inducing pressure in the printer with air pressure reduction to pull the exhaust through the collection media, for example with a pump or fan used to produce air pressure reduction. The method may comprise inducing airflow in the printer with ventilation holes or by the addition of a fan to provide a fresh air inlet. The air/hydrocarbon mixture may be directed to the collection media by a transportation system.
