Abstract: The present invention provides a printing assembly which includes a printing drum such as an impression drum, a pair of eccentric bearings between and on which the drum is mounted for rotation, a pair of self aligning bearings on which the eccentric bearings are supported, and a pair of frameless motors directly connected to the eccentric bearings in order to effect the rotation thereof through closed loop feedback control, in order to facilitate the automatic and accurate control of pressure level and uniformity along the nip of a printing press.

Abstract: A method and system for maintaining a substantially uniform pressure between a pair of rollers is disclosed.

Abstract: A printing device for printing on a printable media. The printing device comprises a rotating component (1), a gripper mechanically coupled to the rotating component (1) and configured for loading and unloading the printable media to and from the rotating component (1), an actuating element (5) configured for actuating the gripper, the actuation resulting in a disturbance to the rotation of the rotating component (1), and a compensating element (6) shaped such as to reduce the disturbance by applying a compensating mechanical force to the rotating component (1) during the rotation of the rotating component (1).

Abstract: A device for holding a photoreceptor sheet onto a drum of an electro-photography printing device comprises first and second holding surfaces that are configured to hold an edge of the photoreceptor sheet from opposite directions by pressing against the sheet in a substantially perpendicular direction with respect to the surface of the sheet, wherein at least the second holding surface is pre-loaded.

Abstract: Apparatus and methods for improving print quality and print blanket life in liquid electrostatic printing, for example, forming a first toner image on an image surface; first transferring the first image to an intermediate transfer member; then transferring of the first image from the intermediate transfer member to a final substrate; affixing the first image on the final substrate; rotating the first image to create a second image; and, repeating the method using the second image.

Abstract: A gripper system for controlling the loading and unloading of sheets on a cylindrical sheet guide. The gripper system comprises one or more grippers, which are positioned at an outer edge of the cylindrical sheet guide. Each gripper is coupled to a cam follower. The gripper system further comprises a cam, which is configured for affecting the elevation of the gripper(s) by moving the cam follower(s), and a servomotor, which is adapted for steering the cam. A cam-gripper controller is provided for controlling the servomotor according to a current printing profile.

Abstract: This invention relates to an apparatus for assuring media feeding, comprising: an impression drum having a media gripper; an input feed unit located substantially adjacent to the impression drum for feeding a sheet of media; and a servo motor operatively connected to the input feed unit such that a change in operating characteristics of the servo motor is detected if the sheet of media is properly retained by the gripper.

Abstract: A multi-printer system comprising: a plurality of imaging apparatus, each said apparatus comprising at least one liquid-toner reservoir, containing liquid toner; a central source of toner concentrate; a toner concentrate conduit which connects the central source to the individual imaging apparatus; and at least one toner-concentrate pump which pumps the toner concentrate from the central source to the individual imaging apparatus.

Abstract: A method of processing a photoconductor comprising: providing a photoconductor having a base layer and a photoconductive layer; bending the photoconductor with the photoconductive layer facing outward without subjecting the photoconductor to substantial external stress other than by virtue of said bending; heat treating the bent; and allowing the bent photoconductor to cool.
