    摘要： A process motor (82) provides bidirectional motive force to a printer (50) drive train (80) that selectively engages with multiple self-homing printing functions. A print head (52) is tiltable to a maintenance position and a transfer roller (64) is loadable against a transfer drum (54) by respective missing tooth gear (96, 160) latching mechanisms. A print media pick roller (122) and transfer drum maintaining devices (70, 72) are actuated by spring-wrap clutches (114, 236) that are protected from reverse rotation by a one-way clutch (106). Print media transport rollers (140, 142) are selectively engaged with the one-way clutch by an electro-mechanical clutch (128). A picked and transported print medium (56) receives an ink image from the transfer drum and is stripped therefrom by stripper fingers (66) and directed into media exit rollers (212, 220) for delivery to a media output tray (68). The stripper fingers and exit rollers are actuated sequentially by cams (180, 182) that are slaved to the transfer roller loading function.

    摘要： A media sensing system monitors the movement of media along the media pathway (76) as a sheet of printing medium (56) is transported through the printer 50. The media sensing system permits a hand fed sheet of printing medium (56) to be detected by a sensor (302) and signal to be sent to inactivate a print media pick roller (122) that automatically feeds print media. The sensing system senses the transport of print media (56) by print media transport rollers (140, 142) detecting media sheet size, activates the transfer process of an image from the liquid intermediate transfer surface on the transfer drum (54) to a sheet of print medium (56) after pausing the sheet of print medium to synchronize its movement along the media pathway with the imaging process, and activating the preheater (60) to heat the print medium (56) prior to image transfer and fusing. The sensing system senses the exit of the print medium (56) from the media exit rollers (212, 220) for delivery to an output tray (68).

    摘要： An image transfer mechanism includes a pressure element and a lever system. The lever system has a load attachment point with a range of position that depends on the thickness of a print medium positioned between the imaging element and the pressure element. A load mechanism includes a load connector with a distal end attached to the lever system load attachment point so that displacement of the lever system attachment point causes longitudinal movement of the load connector. The load mechanism applies a load that is substantially constant throughout the range of position of the lever system load attachment point. The load mechanism includes a spring and a crank attached to the spring and to the proximal end of the load connector. The crank is configured so that a change in the spring force produces a lesser change in the load force at the distal end of the load connector.

    摘要： An ink stick for use in a phase change ink jet printer is provided wherein the ink jet printer has an ink feed channel having a feed direction leading to a melt plate. The ink stick comprises an ink stick body having an external surface and an axis of rotation. The ink stick body is adapted for insertion into the ink feed channel so that the axis of rotation is oriented substantially perpendicular to the feed direction. The external surface of the ink stick body forms a circle on a plane that is substantially perpendicular to the axis of rotation.
