Abstract

An electrostatographic reproducing apparatus is described wherein a first frame portion and a second frame portion are oriented relative to each other to define at least in part, a copy sheet transport path with the second frame portion being pivotally mounted toward and away from the first frame portion thereby providing open and closed positions with respect to the first frame portion. The first frame portion includes at least one fixed driven sheet transport roll and the second frame portion includes at least one idler nip roll positioned opposite the sheet transport roll in the first frame portion. The second frame portion further including means to bias the second frame portion toward the first frame portion so that the idler nip roll is directly biased into driving engagement with the driven sheet transport roll in the first frame portion and the second frame portion is self-referenced against the first frame portion. In a specific embodiment the second frame portion includes a low mass radiant fuser to fix toner images to the copy sheet, and means to guide the copy sheet from the toner transfer station to the fixing station, and the first frame member contains the drive trai…
