ABSTRACT OF THE DISCLOSURE A system for copying large documents on a large document copier having a large document sheet feeder and a large copy sheet or web feeder with improved convenience and efficiency by inserting the leading edge of the large document into the document feeder from the front of the copier, automatically initially rapidly feeding the large document away from the front of the copier with the document feeder, pausing the feeding of the large document in a position wherein a trailing portion is retained in the document feeder but a substantial portion of the document is at the rear of the copier, so that the front of the large document copier is unobstructed, then inserting a copy sheet or webinto the copier from the front thereof for copying, and in response to this and copier activation, first automatically rapidly feeding the large document back in a reverse direction with the large document feeder without copying, up to a position where a leading edge portion of the document is retained by the document feeder, and then, promptly thereafter, automatically again reversing the direction of feeding the document and moving the document at a copying speed synchronized with movement of the copy sheet or web towards the rear of the copier for copying the large document onto the copy sheet or web. The large document is retained throughout all these steps in the document feeder, and these steps are repeated until the selected number of copies is made, without substantial slippage or skew, preferably assisted by plural rigidly supported roller nips.
