Abstract: An electrophotographic imaging device having a method of printing which includes determining whether a duty cycle state in the imaging device has changed; selecting one of a full toner density calibration and a partial toner density calibration based on the determining; performing the one of the full toner density calibration and the partial toner density calibration; identifying a toner density to be applied during printing as a result of the performing; developing a toned image having a toner density equal to the toner density identified; and printing the toned image on a media sheet, wherein the full toner density calibration is skipped upon at least a determination that the duty cycle state has remained the same.

Abstract: An electrophotographic imaging device having a method of printing which includes setting a default toner density for printing; developing a first toned image having the default toner density; printing the first toned image on a first page of a print job; and before printing a second page of a print job, determining whether a duty cycle state of a photoconductive member in the imaging device has changed, and upon a positive determination, developing a second toned image having a toner density derived from the default toner density and printing the second toned image on the second page.

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.
