ABSTRACT:
A moving-document copier wherein a loop-shaped path is used to recirculate a document once for each requested copy, the recirculation path having a skewed turn-around guide which intentionally skews the document's leading edge during recirculation, to avoid document jams. The document is subsequently realigned for rescanning to make another copy. A copy-request counter operates to pivot the skewed turn-around guide to a document-intercept position so long as more copies are needed. When all requested copies have been imaged, the document is allowed to proceed to an exit tray.
