    摘要： Disclosed is a seamless belt comprising a laminate of a conducting polymer layer and a host polymer layer. The process for preparing the seamless belt comprises electrochemically polymerizing onto an electrode a layer of a conductive polymeric material, followed by electrophoretically depositing a layer of a host polymer onto the layer of conductive polymeric material. Also disclosed is an imaging member comprising a substrate and a photogenerating layer, wherein the substrate comprises a laminate as described above. An imaging process which comprises incorporating into an ionographic imaging device an imaging member comprising a laminate of a conducting polymer layer and a host polymer layer as described above, generating a latent image on the imaging member by ion deposition, developing the latent image with a toner, transferring the developed image to a substrate, and permanently affixing the transferred image to the substrate is also disclosed.

    摘要： A method and apparatus can, while operating a printing device in a test mode, supply a changed transfer field to a marking material transfer device. The changed transfer field is less than or more than the standard transfer field. The method and apparatus disable operations of other marking material transfer devices of the printing device to isolate the marking material transfer device. Further, the method and apparatus compare the actual amount and/or spatial distribution of marking material transferred to a recipient surface (to which the first marking material transfer device transfers the marking material) against a predetermined standard. Then, if the actual amount of marking material transferred to the recipient surface is different than the predetermined standard, the method and apparatus can identify the first marking material transfer device as being a potential source of printing defects.

    摘要： An apparatus, printing machine and method for replenishing an aquatron liquid reservoir in an aquatron charging device. The print media (e.g. paper, vellum, etc.) releases liquid from the print media during fusing. A condenser creates condensate from the liquid released by the print media which is collected in a conduit and transported using air flow into a collection container. This collection container can be the aquatron liquid reservoir, or a separate collection container that pumps liquid to the aquatron liquid reservoir, thus, enabling replenishing the liquid supply of the aquatron liquid reservoir within the printing machine. Sensing devices measuring liquid concentration resistance in the aquatron liquid reservoir and/or the collection container control the liquid level of the reservoir and/or collection container.
