Abstract
A media-sheet stacking system (10) for stacking media sheets on a device output tray (OT) comprises a kicker (25) to advance a media sheet along the output tray by pushing a trailing edge of the media sheet as it exits the device, and a movable element (32a) arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism (33) is provided to drive the movable element in the direction of advance of the media sheet along the output tray.
Claims13
A media-sheet stacking system for stacking media sheets on an output tray for a device, the stacking system comprising:
- a kicker to advance a media sheet along the output tray by pushing a trailing edge of the media sheet exiting the device, wherein the kicker is moveable between an extended position and a retracted position, the kicker to retract from the extended position to the retracted position responsive to the trailing edge of the media sheet exiting the device, and after the kicker has retracted from the extended position to the retracted position, the kicker is to extend from the retracted position to the extended position to push the media sheet onto the output tray;
- an output roller to push the media sheet to the output tray;
- a sensor to sense presence of the media sheet, wherein the kicker is to retract from the extended position to the retracted position responsive to the sensor ceasing to detect the presence of the media sheet;
- a movable element arranged to face the output tray across a space receiving media sheets exiting the device;
- and
- a drive mechanism to drive the movable element in a direction of advance of the media sheet along the output tray.
