ELEKTROGRAFISCHER DRUCKER/KOPIERER MIT DUPLEXDRUCKMODUL

摘要

A duplexing unit, which is attachable as a module to the body of an electrographic printer to convert it from a simplex printer to a duplex printer, comprises a first paper path (22-2) along which the first side of the paper is imprinted from below in a transfer zone (25) and a second paper path (22-5) to receive printed paper after it has passed through the transfer zone (25), turn the paper over and return it to the first paper path prior to the transfer zone so that the second side of the paper is imprinted from below by the photoconductive member (10). As described, copy material is taken from trays (20, 21) and final prints output to tray (25). <IMAGE>
