Abstract: A media accumulator-ejector for use with an imaging apparatus. Rotatable upper and lower roll assemblies are located above and below a media accumulation zone comprised of an accumulation plate and positioned to receive media exiting an imaging device. The roll assemblies are moveable like jaws between an open position where media can accumulate on the accumulation plate without interference with the roll assemblies and a clamping position where the accumulated media is grasped by the upper and lower roll assemblies. The upper and lower roll assemblies are then rotated to eject the accumulated media from the accumulation plate. The upper and lower roll assemblies can also grasp and continuously eject individual sheets of media at a predetermined process speed.

Abstract: A media stapling system for an image forming device. The media stapling system comprises a stapler mounted on a motor-driven carriage assembly moveably coupled to a track having portions extending along at least two contiguous edges and included corner of a media stack to be stapled. The carriage assembly and track enables stapling in multiple positions along the long and/or short edges and corners of media of varying sizes positioned in a media support. The track is mounted on a planar frame positioned at an angle from horizontal, providing a relatively small footprint. A controller is in operable communication with the media stapling system and an user interface. The user interface provides a plurality of predetermined stapling patterns for selection with the controller controlling the media stapling system to staple the media stack using a selected one of the plurality of stapling patterns.

Abstract: A media diverter system for an imaging device including a single motor coupled to one of a plurality of diverter assemblies for sequentially directing media sheets from an input path to one of a plurality of output destinations. Each diverter assembly includes a gate moveable between a first and a second position for opening a path between an input and a first and a second output, respectively, a pivot arm coupled to the gate, and a drive gear providing a lobe having up and down camming surfaces on which the pivot arm travels. The single drive motor rotatably is coupled to the drive gears, and, as the drive motor is driven, the drive gears synchronously rotate and corresponding gates are moved to one of a first and a second position for providing a media path from an input of the system to a selected one of the output destinations.

Abstract: A translatable media height sensor assembly for measuring a media stack in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. Insertion assembly includes a translatable plunger having mounted thereon a sensor and a translatable probe. At a home position, the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, drive assembly translates insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe initially encounters the media stack and stops while plunger continues to translate. As the plunger reaches the media stack, the probe engages the sensor causing the sensor output to again change state and stops the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.

Abstract: A translateable media height sensor assembly for measuring a media stack height in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. The insertion assembly includes a translateable plunger having mounted thereon a sensor and a translateable probe. At a home position the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, the drive assembly translates the insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe encounters the media stack and stops while the plunger and the sensor continue to translate with the probe engaging the sensor causing the sensor output to again change state and stop the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.

Abstract: A method to compensate for imperfect scanner motion in a scanning apparatus having a moveable scanner includes generating an error array by measuring errors in a scanner position at each of a plurality of spaced positions along a direction of travel of the scanner; generating an error compensation array from the error array based on a low frequency component of the error array; and using the error compensation array to adjust at least one parameter associated with the scanning apparatus during a document scanning operation.

Abstract: An ink jet printer includes a printhead and a maintenance station. The maintenance station includes a fixed support housing, a sled and a chimney. The sled is supported on the support housing and is movable relative to the support housing in both a horizontal direction and a vertical direction. The chimney receives ink spit from the printhead. The chimney has a fixed vertical position relative to the printhead and is horizontally movable in response to movement of the sled.

Abstract: A printer exit tray assembly attachable to a printer housing and a computer printer including a printed paper exit tray assembly. The exit tray assembly has an exit tray and a pair of sheet supports attached to the exit tray. The exit tray is movable between a use position and a collapsed position. The exit tray is positioned generally horizontally in the use position. The exit tray projects horizontally further from the printer housing in the use position than in the collapsed position. When the exit tray is in the use position the supports are pivotable, with respect to the exit tray, between a support position for supporting a printed sheet above the exit tray and a release position for releasing the printed sheet to the exit tray.

Abstract: A serial drop-on-demand ink jet printer having an ink cartridge mounted for reciprocation on a carrier which traverses paper advancing through the printer. The cartridge includes a nozzle array for the ejection of ink droplets onto the paper, and the carrier includes a tab upstream from the nozzle array, in the direction of paper travel, which touches the top surface of the paper and sets the printhead-to-paper gap. The paper is pushed against the tab and maintains a minimum gap to prevent paper from coming into contact with the nozzle array. The paper is urged against the tab into the proper position relative to the nozzle array by a deflectable guide which acts on the back surface of the paper.
