摘要： An inkjet printer has been developed that reduces the effects of show-through by depositing ink onto a cooled print medium. The inkjet printer includes a printhead and a cooler. The printhead is configured to eject ink onto an ink receiving member as the ink receiving member is transported along a portion of a media path through the inkjet printer. The cooler is positioned proximate the media path to cool the ink receiving member prior to the printhead ejecting ink onto the ink receiving member.

摘要： An apparatus for developing an electrostatic latent image on an image support surface. A rotating advancing member advances single component developer material from a toner supply sump in a chamber to an intermediate donor roll. The intermediate donor roll transports a metered amount of developer material to a down roll adjacent to the latent image where the developer material is attracted to the latent image for development thereof. The intermediate donor roll is provided in configuration with the donor roll for preventing escape of developer material from the chamber to increase the life of mechanical components and to decrease background.

摘要： An electrophotographic apparatus in which toner particles are moved from the toner hopper or dispenser cartridge to the developer housing and onto the donor roller in a single component development system for use in color reprographic systems. A rotating holey tube toner agitator is modified to incorporate structure or grooves on the outer peripheral surface. Further, by placing a shrouded toner dispense auger inside the holey tube, the development system architecture stays compact and improved toner powder pushing through the pre-load of toner on the donor roller results, thereby insuring delivery of fresh toner evenly across the length of the developer housing. With more efficient pre-load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle to cycle donor roller toner reload.

摘要： A system for removing residual contaminants from an image conditioning apparatus that removes excess liquid from a developed image made up of toner particles immersed in a liquid carrier medium on an image bearing member. The system includes a vacuum blotting device that contacts the liquid developed image and absorbs a portion of the liquid carrier and residual contaminants remain thereon. A contact member adapted to be shifted from a non-operative position spaced from the vacuum blotting device, to an operative position in contact with the vacuum blotting device operates to transfer the contaminants therefrom. A scraper removes the transferred contaminants from the contact member. The contact member is pivotally mounted about the pivot point to effect shifting of the contact member between the non-operative and the operative position.

摘要： An electrostatographic liquid immersion development (LID) reproduction machine having an image bearing member and a multifunction image developer and conditioning apparatus that significantly reduces the number of components, size, costs, and shear-force related image defects of such machines. The multifunction apparatus includes a housing defining a sump portion, a recovery chamber, and an opening into the recovery chamber; liquid developer material contained in the sump portion for developing a latent image on the image bearing member; and a rotatable multifunction roller assembly for processing a developed image on the image bearing member. This roller assembly includes a rotatable roll having a porous metal core defining an inner surface, and a foam layer formed over the metal core defining a skin or outer surface. The rotatable roller is mounted partially within the recovery chamber and partially through the opening and into contact with the image bearing member to form an image processing nip therewith. The rotatable roller functions to transport liquid developer material into the image processing nip for developing a latent image on the image bearing member, and to apply a mechanical force against the image bearing member for compacting and stabilizing a developed image thereon. The roller assembly also includes a vacuuming device mounted inside the rotatable roller against the inner surface thereof for applying a liquid carrier removing vacuum to a portion of the inner surface of the rotatable roller within the image processing nip.
