Abstract:
A print media transport device 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 upstream pair having one driven roller, the downstream pair having one pulley roller; a flexible coupling between the one driven roller and the pulley roller of the downstream pair; a selectively positionable mechanism for changing tension of the flexible coupling such that predetermined shaping and positioning of media is maintained in the path, wherein the selectively positionable mechanism is movable between 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 wherein a printing surface of the media does not contact the frame in either position; a movable carriage mounted to the frame adjacently to a bottom of the path; and a set of tension rollers mounted to the carriage such that the flexible link is routed between the tension rollers and the link is in tensioning contact with one of the tension rollers in the first position and the other of the tension rollers in the second position wherein tension of the media in the path is relaxed.
