Abstract: An apparatus for assisting in the removal or waste or excess ink and a method for disposal of ink from electrophotographic printers comprises providing electrophotographic ink from a source, combining the ink with an absorbable material in a container to form a solid within the container, and closing the container so that the container with the solid inside may be disposed of without ink flowing from the container.

Abstract: Electrophotographic ink compositions display reduced malodor effects when at least one antagonistic odor vector compound for C10, C11 and C12 hydrocarbons is present in the ink composition. The use of appropriate amounts of the antagonistic odor vector compounds for C10, C11 and C12 hydrocarbons does not adversely affect the functional imaging properties of the ink.

Abstract: A method of producing a composite image on a final image receptor from image data in a single pass electrophotographic system is provided. The method includes steps for applying liquid transfer assist material comprising charged particles of transfer assist material to at least a portion of an element of the electrophotographic system, along with charged toner particles, in order to provide a composite image layer on a final image receptor in a single pass of a photoreceptive element through transfer of the composite image layer from another element in the system.

Abstract: A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method comprises the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit comprising 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 comprises 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.

Abstract: 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.

Abstract: An electrophotographic imaging apparatus has a first toner accepting layer and an intermediate transfer member. The first toner accepting layer is positioned in electrical contact with a) a charge provider, b) an irradiation source that activates photoconductivity in the first toner accepting layer, and b) at least one toner applicator, so that a first toner image can be formed on the first toner accepting layer. The first toner layer is movable (after interaction with a), b) and c)) into contact with the intermediate transfer layer from which the first toner image can be transferred to an image bearing member. The intermediate transfer member comprises a non-conductive flexible film layer, a layer of an electrically conductive material affixed to a first surface of the non-conductive flexible film layer, and the electrically conductive material layer has an electrically resistive polymeric coating thereon.

Abstract: Method and apparatus for maintaining the focal point of a laser beam used for laser machining relative to a workpiece, including an optical distance measuring sensor having a measurement beam, a mirror for combining the measurement and laser beams into a predetermined optical path having a common axis for both beams, and a focusing element which may be in the form of a refractive lens or a reflective parabolic mirror located in the optical path, and a control means for controlling the location of the focal point of the laser beam based on the distance sensed by measurement beam. In drilling, once the hole breaks through the workpiece, the application of the laser beam can be stopped by observing a departure from the incremental distance measurement change.
