Abstract

A copying system utilizing a recirculating document handler (RDH) presenting documents to the platen of a copier for copying, with an RDH document stacking tray and an additional document input directly to the platen, and a three zone distributed drives feeding system for first feeding the documents from the stacking tray to the platen, secondly feeding the documents over the platen for copying, and thirdly feeding the documents from the platen back to the stacking tray after they have been copied, to normally form a compIete document recirculation path, and sensors for sensing document jams and the position of jammed documents in the document ath connecting with a control system controlling the RDH and

This system provides improved jam clearance and job recovery by determining whether a document 'am has resulted in a jammed document being present in a first, second, or third document ath jam zone, corresponding to the three distributed drive zones, an
