ABSTRACT:
A method of recirculative precollation copying of simplex documents in forward serial page order by stacking the set of simplex document sheets in proper page order, but face-down and overlying the imaging station, and circulating the document set in its first and last circulations through a non-inverting reversing document path between the stack and the imaging station. In all other circulations of the document set the documents circulate through a different, unidirectional, document path with two inversions, with a single inversion between the stack and the imaging station and another common inversion between the imaging station and the stack used in all circulations, to provide proper simplex/duplex copying of an odd or even number of simplex documents without counting them before they are copied.
