ABSTRACT:
A sheet stacking and feeding system for a copier with an integral normal force/jogger unit allowing continuous and simultaneous top loading and bottom feeding from opposite or common directions from a stack of documents or copy sheets. Disclosed are continuously rotating foraminous spaced counterbalanced jogging rollers engaging the top of the stack to provide lead edge or trail edge sheet pull-down and stacking registration against the front stack stop, and to provide a controlled uninterrupted normal force to edges of the feed belt of a bottom sheet retard feeder. This system is disclosed in a copying system for copying either duplex or simplex original document sets as pre-collated copy sets. A document handling system provides automatic recirculative pre-collation copying of duplex or simplex document sheets with selective different sheet inversion and different sheet restacking directions.
