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 crystalline phase of titanyl oxyphthalocyanine, referred to herein as the S-phase, has an internal blend of lattice arrangements is provided by treatment of the gamma-form of titanyl oxyphthalocyanine. The S-phase is a truly new phase, and not a mixture of particles of various phases (e.g., combinations of the beta-phase and the gamma-phase), with internal lattice distributions of atoms and molecules forming a new, non-continuous, non-uniform lattice structure. The x-ray spectrum shows a blend of diffraction peaks, having peaks that have previously been distinctly present only collectively among various crystalline forms of titanyl oxyphthalocyanine, but can now be provided in a single crystalline form. The visible spectra show significant absorption differences. The novel S-form titanyl oxyphthalocyanine is also used in a photoconductor displaying major peaks of Bragg's 2 theta angle to the CuK-alpha characteristic X-ray (wavelength 1.541 Angstrom) at least at 9.5±0.2 degrees, 9.7±0.2 degrees, 11.7±0.2 degrees, 13.5±0.2 degrees, (optionally at 21±0.2 degrees and/or 23.5±0.2 degrees,) 24.1±0.2 degrees, 26.4±0.2 degrees, and 27.3±0.2 degrees group. Additional peaks, approaching or equivalent to major peaks, may also be present as 15.0, 15.3 and 16.0±0.2 degrees.

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.
