Abstract: Various embodiments of a system and method for picking print media are disclosed.

Abstract: Various methods and apparatus relating to a media interaction device drive system having at least one reduced dimension are disclosed.

Abstract: A sheet feeder has a tray for receiving one or more media sheets. An arm is configured to pivot relative to the tray. A roller is rotatably coupled to the arm. A biasing device is coupled to the arm. The biasing device biases the arm to pivot toward the tray.

Abstract: An automatic document feeder transmission includes a single electric motor mounted on a chassis. Motor actuates a power input gear that is rotatably mounted on the chassis and has gear teeth. A swing arm, rotatably mounted to the chassis, pivots about a swing arm pivot axis through an arc of travel. Arm has central and distal ends, the latter having gear teeth formed therein. Driving and driven pinions, each having mutually intermeshing gear teeth, are rotatably mounted to the arm. Driven pinion gear teeth also intermesh with power input gear teeth. A paper stop is rotatably mounted on the chassis. A catch, disposed on the arm, is selectively engageable with a wire spring disposed adjacent portion(s) of the travel arc, wherein arm rotation is selectively stopped in one direction and allowed in an opposite direction. Arm selectively switches between three discreet feeder modes and selectively actuates the paper stop.

Abstract: One embodiment of a mechanism may include a member having a first axis and a surface non-concentric with said first axis, a first gear rotatably mounted on said member at a second axis different from said first axis, and a device coupled to either of said member or said first gear to rotate said member when said first gear rotates about said second axis.

Abstract: A service station servicing an ink-jet printhead of an ink-jet printing system. The service station includes a sled structure, and an elevator mechanism coupled to the sled structure for moving the sled structure between a rest position and a sled capping position. A printhead cap is supported on the sled structure, and is movable relative to the sled structure for movement between a retracted position and a printhead capping position. The cap is adapted to surround and seal the printhead nozzles when the sled has been moved to the sled capping position and the printhead cap has been moved to the printhead capping position. A piston is carried by the sled structure, and the printhead cap is mounted to the piston. An actuating mechanism moves the piston from a retracted position to an extended position, wherein the printhead cap is positioned at the printhead capping position when the piston is moved to the extended position.

Abstract: A multi-function sheet handling system including an automatic document feeder (ADF) for automatically feeding sheets of a document held in an ADF input tray. An ADF pick roller selectively picks a sheet of the document and advances the picked sheet along an ADF path. The system includes an automatic sheet feeder (ASF) for automatically feeding sheets of a print media held in an ASF input tray. An ASF pick roller selectively picks a sheet from the ASF input tray and advances the picked sheet along an ASF path. The system further includes an ADF gear for driving the ADF roller, an ASF gear for driving the ASF roller, and a motor drive including a gear train, the motor drive including a stepper motor or other motor with position control. A three-state shifting device couples the motor drive gear train to the ADF and the ASF gears.

Abstract: A multiple-function printing device provides for picking pages from a stack of sheets in an input feeder for roller-driven movement along a first path through a printing station to an output, and for picking pages from a stack of documents in an input feeder for roller-driven movement along a second path through a scanning station to an output, with at least a portion of the first and second paths being commonly shared, with a document deflector which, in a document scanning mode of operation, is pivoted into a lowered position generally parallel to a print station platen to constrain the top and bottom of curled documents exiting from the scan station so as to prevent an incipient paper jam. The deflector is actuated by a drive mechanism including a ball link and cranks connected to a common motor in a service station for capping and wiping print cartridges in the printing station.
