(54) Methods of pre-collation copying


(57) Method of pre-collation copying of simplex documents by recirculating them in forward serial page order in which the set of simplex document sheets is stacked in proper page order, but face-down and overlying the imaging station (23), and circulated in its first and last circulations through a non-inverting reversing document path (58) between the stack (22) and the imaging station (23). In all other circulations of the document set the documents circulate through a different, uni-directional, document path with two inversions, with a single inversion (54) between the stack and the imaging station and another common inversion (42) 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.
