There is disclosed a sheet media processing machine comprising a media inlet to receive sheet media along a feed direction from a first side of the machine and a media outlet to discharge sheet media along a discharge direction towards the first side of the machine. There is a feed mechanism to convey sheet media from the media inlet to the media outlet, and a re-feed prevention element disposed upstream of the media inlet with respect to the feed direction to inhibit recirculation of discharged sheet media along an external recirculation path between the media outlet and the media inlet. The re-feed prevention element is exposed to contact with sheet media and comprises an elastomer. There is also disclosed a feed guide comprising a re-feed prevention element, and a method in which such a feed guide is installed on a sheet media processing machine.

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.
