Abstract
A media transport assembly includes a loadstop drive assembly to gather and compress a media stack in a media tray before a pick and feed cycle, and a pick drive assembly to pick a sheet of media from the media stack and feed the sheet of media to a media path. The loadstop drive assembly is positioned on one side of a gear wall and the pick drive assembly is positioned on an opposite side of the gear wall such that the pick drive assembly is driven by the loadstop drive assembly through the gear wall.
Claims8
A media transport method, comprising:
- feeding a first sheet of media through a media path during printing and ejecting the first sheet of media after completion of the printing;
- and
- during the feeding and the ejecting the first sheet of media, loading a second sheet of media into the media path and deskewing the second sheet of media,
- wherein the loading and the deskewing the second sheet of media includes:
- maintaining a loadstop paddle of a loadstop drive assembly in a retracted position, the loadstop paddle configured to gather and compress media prior to loading media,
- engaging a pick swingarm assembly of a pick drive assembly with an idler gear of a speedmech swingarm assembly of the pick drive assembly to drive a pick tire of a pick mechanism in one direction,
- moving the loadstop paddle of the loadstop drive assembly to a load position and actuating a speedmech lock lever of the loadstop drive assembly to unlock the speedmech swingarm assembly of the pick drive assembly, and
- disengaging the pick swingarm assembly of the pick drive assembly from the idler gear of the speedmech swingarm assembly and engaging another idler gear of the speedmech swingarm assembly with the pick swingarm assembly to continue to drive the pick tire of the pick mechanism in the one direction.

- and
- during the feeding and the ejecting the first sheet of media, loading a second sheet of media into the media path and deskewing the second sheet of media,
- the loading and the deskewing the second sheet of media including actuating a pick arm with a pick swingarm assembly and driving a pick tire of a pick mechanism in one direction with rotational input of both a first direction and a second direction opposite the first direction to a speedmech swingarm assembly engaged with the pick swingarm assembly,
- wherein the loading and the deskewing the second sheet of media further includes:
- maintaining a loadstop paddle of a loadstop drive assembly in a retracted position, the loadstop paddle configured to gather and compress media prior to loading media;
