ABSTRACT:
An electrophotographic print engine with a photosensitive flexible belt stretched over a plurality of rollers in a compact electrophotographic printer such that a developing position on the belt is disposed in a vertical plane, the developing position exposed first to a light on one side of the printer and activated to trace the image of the document to be printed and second passed vertically adjacent at least one toner module extending a decorator roller horizontally to the photosensitive belt on a second side of the printer to create a developed image, the developed image transferred at the upper end of the vertically disposed belt to the downward facing side of a sheet of paper which passes through a fuser to fix the print before the paper is placed facedown in an output tray, permitting the compact printer to create multi-page documents in sequence without manual re-sorting of the document, residual toner wiped from the vertically disposed belt to fall by gravity to a modular collection receptical.
