Abstract:
When an insufficient quantity of a preferred print media is installed in a selected printing device, methods and systems automatically output an insufficient-print-media notice and one or more reconfiguration options for proceeding with printing the print data on one of the installed print media types. In response, a selected reconfiguration option is received that identifies an alternative print media to be used in place of the preferred print media when executing the print request. Additional processing is performed to print the print data on the alternative print media including: automatically resizing the print data to fit on the alternative print media; automatically printing a cutline on the alternative print media to indicate where the alternative print media should be cut to be reduced to the preferred print media; and automatically formatting multiple pages of the print data to print on one page of the alternative print media.
Abstract:
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.

Embodiments according to the present disclosure provide methods and systems of determining nip velocity profiles in a medium registration system, including parameterizing a set of equations into a set of standard parameters, the set of equations representing an analytic form of the nip velocity profiles; determining values of the parameters through an iteration process; and determining the nip velocity profiles based on the determined values of the parameters. The embodiments separately provide systems and methods of simulating a medium registration process, including inputting an error parameter to a velocity nominal profile of a nip in a medium registration system; determining an output value of the velocity nominal profile; and using the output value in a regression algorithm to obtain a simulated relationship, the simulated relationship indicative of a manner in which the error parameter influences the output value. The embodiments separately provide systems and methods of determining an angular velocity of a medium relative to a nip in a medium registration system, including determining a path of the nip on the medium; and determining the angular velocity as a function of a position of the nip in the path. The embodiments separately provide systems and methods of controlling nips of a medium registration system, including wagging a medium relative to a center line of two nips of the medium registration system; and then unwagging the medium relative to the center line of the two nips.

Abstract:
An image transfer mechanism for a printer having a printer frame and an imaging drum attached to the printer frame includes a roller arm having a proximal end and a distal end, a transfer roller having a longitudinal axis, and a load arm having a proximal end and a distal end. The axis of the transfer roller is rotatably attached to the roller arm. The proximal end of the roller arm is attached to the load arm between the proximal end and the distal end of the load arm. The proximal end of the load arm is pivotally attached to the printer frame, and a load mechanism applies a load force to the distal end of the load arm to urge the load arm toward the imaging drum. An engaging mechanism selectively urges the distal end of the roller arm toward the imaging drum, which presses the load arm against the load force of the load mechanism.
Abstract:
A gear assembly for a print device includes an input gear connected to a drive shaft of a motor, a first output gear and a second output gear. The first output gear operates a transfix roller in the print device and is spaced relative to the input gear to allow teeth of the input gear to mesh with teeth of the first output gear. The first output gear includes a first toothless portion that does not mesh with teeth of the input gear when the input gear is adjacent the first toothless portion. The second output gear operates a drum maintenance system in the print device and is spaced relative to the input gear to allow teeth of the input gear to mesh with teeth of the second output gear. The second output gear includes a second toothless portion that does not mesh with teeth of the input gear when the input gear is adjacent the second toothless portion. The gear assembly further includes a swing arm for rotating the first output gear when the input gear is adjacent the first toothless portion and the. second output gear when the input gear is adjacent the second toothless portion. The rotation of the first output gear moving the first toothless portion away from the input gear and allowing teeth of the input gear to engage teeth of the first output gear. The rotation of the second output gear moving the second toothless portion away from the input gear and allowing teeth of the input gear to engage teeth of the second output gear.

Abstract:
A document collector, stager and diverter apparatus and method are provided for processing sheet articles through a first and second stage. The first stage is adapted for receiving sheet articles advanced thereto and collected therein and includes a first transport mechanism being operative for selectively diverting collected sheet articles in a divert direction opposite to the conveying direction of the sheet articles. Alternately, the first transport mechanism is operative for selectively advancing the collected sheet articles from the first stage to the second stage. In the second stage, sheet articles can be independently processed and held until a predetermined time when they can be advanced from the second stage by a second transport mechanism. The first and second transport mechanisms each preferably includes plastic chains each with plastic lugs thereon. The chains of the first and second transport mechanisms are simultaneously rotatably movable by a motor and gears or pulleys associated therewith.
Abstract:
A lightweight chain apparatus is provided for rotation in a high-speed media processing apparatus for particularly causing media to be conveyed. The chain apparatus includes a plastic chain having a series of substantially parallel rollers maintained in a spaced-apart relationship by a series of interconnected link plates positioned on opposing ends of the rollers wherein the rollers and the link plates are constructed of different materials. One or more push members are mounted on the chain for engaging and conveying media, and each push member includes opposing substantially parallel push plates attached substantially perpendicularly to opposing ends of at least a pair of the rollers so as to link the pair of rollers. Each push member forms a laterally extending portion which can be supported against adjacent link plates of the chain for increased stability and longer life when the push member encounters media to be conveyed.
