ABSTRACT:
The duplex copying of two-sided originals onto two sides of a copy sheet is accomplished by interspersing images from two successive documents on a multi-image imaging member, specifically with the front-side image of a second document interspersed between the front and rear-side images of a first document. Copy sheet turnover can thus occur during the transfer of the front-side of the second document to achieve an increased "copy-output-rate to electrographic-procedure-speed" ratio.
