摘要： A single pass EP color printer includes a photoreceptor web having multiple layers and including a charge transport layer and a charge generation layer. Four exposure devices (e.g. either laser-based or thin film electroluminescent edge emitting (TFEL) devices) are serially arrayed along the photoreceptor web and act to expose the photoreceptor web in accordance with cyan, magenta, yellow and black color image pixel data. A liquid toner developer module is associated with each exposure device and includes a liquid toner reservoir, a developer roll for carrying the liquid toner to a transfer point and a squeegee roll. Each developer module is fixed so as to position its developer roll at a constant prescribed distance from the photoreceptor web at the toner transfer point and to create a fluid interfacial layer between its developer roll and the photoreceptor web. In addition, each squeegee roll is maintained in constant contact with the photoreceptor web. Erasure devices and corona charging devices are positioned between the respective developer modules to enable preparation of the photoreceptor web for a subsequent exposure/development operation. A drying roll is positioned after a last developer module for fixing the imaged toner on the photoreceptor web. The exposure devices operate from either the lower side of the photoreceptor web or from the upper side; however, in the latter instance, the photoreceptor web is comprised of a transparent support and ground plane layer. Additional embodiments of the invention are disclosed which employ a dielectric powder toner and a liquid toner four pass system.

摘要： Electronic display devices and methods are described. In one embodiment, a display device comprises a housing with a display area to display content for a user. Memory within the housing holds data that is to be rendered into user-viewable content. A loop of material is provided within the housing and is configured to display user-viewable content for the user. An exposure station is provided internally of the loop of material and is configured to expose selected portions of the loop of material so that the loop of material can receive and retain toner thereon to provide the user-viewable content from the data that is held in the memory. In another embodiment, a display device comprises a toner shuttling system within the housing that is configured to shuttle toner between different locations within the housing from which the toner can be used and reused. The shuttling system, in one implementation, takes the form of multiple toner reclamation/development stations, each of which being configured to operate to either reclaim toner or develop toner. The stations are desirably configured so that when one station operates to reclaim toner, another station operates to develop toner. In one particular implementation, the stations comprise a pair of switchably-biasable, bi-modal reclamation/development stations where, in one mode, a station develops toner and, in the other mode, the station reclaims used toner. Reclamation of toner can advantageously take place through non-invasive techniques, e.g. electrostatic techniques.

摘要： Embodiments of a wet contact charging method and apparatus for electrophotography charging stations are shown and described. Each embodiment includes placing a charging member, having a charge bias, against an electrophotography charge-receiving member, and placing a liquid between the charging member and charge-receiving member. Preferably, a charging roller is rotated through a liquid-filled container and the wet roller carries liquid into the nip between the roller and a photoconductor. This wet contact charging results in stable, uniform charging without photoconductor release property degradation.

摘要： An electrostatically assisted transfer roller is rotatably mounted to be driven directly against one surface of an adjacent print media and against an adjacent surface of a photoconductive drum at the other opposite surface of the print media. This transfer roller is operative to transfer transparent developed liquid color toners from the surface of the photoconductive drum and onto the print medium using a combination of mechanical forces, electrostatic forces, and thermal energy. The transfer roller includes a metal inner sleeve member within which a heat source is suitably mounted, and an outer non-metallic sleeve member is positioned around the inner sleeve member and is preferably a conductive silicone or conductive polyurethane material. A thin outer overcoat layer is disposed on the outer surface of the outer sleeve member and is adapted to be driven directly against an adjacent surface of the print medium. A source of DC bias voltage is connected to the metal inner sleeve member to thereby develop electrostatic forces at the surface of the print medium for assisting in the efficient transfer of color images thereon having good print quality.
