Abstract
A media-sheet stacking system for stacking media sheets on a device output tray comprises a kicker 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 arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism is provided to drive the movable element in the direction of advance of the media sheet along the output tray.
Claims20
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 a retracted position to an extended position to eject 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.
A printer comprising:
- a media-sheet stacking system comprising:
- a kicker to advance a media sheet along an output tray by pushing a trailing edge of the media sheet exiting a printing device, wherein the kicker is to extend from a retracted position to an 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 belt arranged to face the output tray across a space receiving media sheets exiting the printing device;
- and
- a drive roller to drive the movable belt in a direction of advance of the media sheet along the output tray.
A method of stacking media sheets on an output tray for a device, comprising:
- pushing, by an output roller, a media sheet to the output tray;
- activating a kicker to advance the media sheet along the output tray by pushing a trailing edge of the media sheet exiting the device, wherein the kicker extends from a retracted position to an extended position to eject the media sheet onto the output tray;
- retracting the kicker from the extended position to the retracted position responsive to a sensor ceasing to detect a presence of the media sheet;
- and
- moving at a speed faster than the speed of advance of the media sheet, and in a direction of advance of the media sheet along the output tray, a movable element facing the output tray across a space receiving media sheets exiting the device.
