    摘要: An inkjet printer having a printhead closely adjacent a platen and a printzone therebetween has first and second juxtaposed counter-rotating feed rolls for transferring recording media from a first location where a media leading edge is located in an entrance nip between the first and second rolls and a second location where a media trailing edge is located in an exit nip between the first and second rolls. Printer control avoids printing to a media free printzone by sensing for the presence of a sheet of recording media within a nip between the primary and secondary feed rolls and selectively enabling and disabling the printer in accordance with the sensed media presence. The transverse dimension of a sheet of recording media may be estimated by multiple sensors and printer carriage travel limited to less than the estimated dimension.

    摘要: Bracket (1) containing a gear train holds the end of spring (19) wound in a direction to be opened when the bracket moves up from the paper tray (7). Spring (19) is wound on an arbor (15) which is mounted on a shaft (9) which is located on the pivot axis of the bracket. Spring (17) is wound on a second part of the arbor in a direction to be closed when the bracket moves away from the tray. Spring (19) has a much tighter grip on the arbor than spring (17). In operation the bracket resists upward movement under the influence of stiff paper being fed, and is slowed in its downward movement to reduce bounce, which increases the speed at which a second sheet can be fed.

    摘要: A sheet separator and apparatus utilizing the same for separating media sheets in an image forming device. The apparatus includes a supporting member for supporting a stack of media sheets, a pick assembly to pick media sheets and to feed the media sheets to a processing assembly of the image forming device, and a media dam having at least one sheet separator. Each sheet separator includes a casing inclined at a predetermined angle to the supporting member, a biasing member and a base member slidable within the casing. A plurality of detents in the form of steps or teeth are provided on a sheet receiving surface of the base member and the biasing member act to separate a top most media sheet from an adjacent media sheet to prevent double feeding of media sheets.

    摘要: A media handling device includes a media shingling mechanism having a roller actuator located adjacent an upper portion of a media stack and upstream thereof relative to a predetermined direction of an uppermost sheet from the stack toward a media restraint dam located downstream thereof. The roller actuator undergoes counterclockwise rotation in response to upward moving contact by successive sheets in the upper portion of the stack against a peripheral segment of the roller actuator as the stack is moved vertically upward in a rectilinear direction toward the roller actuator. The counterclockwise rotation of the roller actuator and upward movement of the upper portion of the stack produces a lateral displacement of successive sheets toward the dam so as to produce shingling of successive sheets of the upper portion of the stack relative to one another, providing a uniform inter-page gap between successive sheets.
