Abstract:
A print media transport comprising:a curved frame defining a media path therein; mounted with respect to the path, a pair of upstream rollers and a pair of downstream rollers, the downstream pair having one pulley roller, the pair of upstream rollers having one driven roller; a flexible coupling connecting the one driven roller and the pulley roller of the downstream pair; and a selectively positionable mechanism for changing tension of the flexible coupling such that predetermined shaping and positioning of media is maintained in the path, the selectively positionable mechanism movable between at least two positions, a first position in which the media is underfed through the path and a second position in which the media is overfed through the path when the media is engaged by the pair of upstream rollers, wherein when the media is contacted simultaneously by the pair of upstream rollers and the pair of downstream rollers, a printing surface of the media does not contact an adjacent guide surface of the frame.
