Abstract

A modular copier/printer or similar image forming apparatus of the type having an image transfer body in the form of a drum or belt allows documents to be reproduced in a paper discharge mode which discharges paper sheets, or recording media, in page-sequential order. When an automatic two-sided copy mode is selected, the apparatus automatically sets up the page sequential paper discharge mode to a "collation mode" through a minimum number of sorter bins which has been optimally designed to correspond with the shortest two-sided copy loop. Hence, when mixed black-and-white documents and color documents are reproduced together in the automatic copy mode, paper sheets exit the apparatus in the correct page order. As a result of this automatic change in operating modes, fewer "skip" frames need be introduced during the copying operation, thereby enabling the copier to produce multiple collated copies of the multipage document very efficiently.
