Electrographic printer/copier with duplex printing

摘要

An electrographic printing apparatus capable of duplex printing comprises a housing, a source of copy material and an output tray for receiving such copy material after it is imprinted, and a photoconductive member for storing a latent electrostatic image of the information to be imprinted. The printer/copier has first and second paper paths located near the top of the housing so that access to the paper may be achieved from the top of the housing. A photoconductive member is located below the first paper path and comes into contact with a first side of the paper from below in a transfer zone located in the first paper path to imprint the first side of the paper. The second paper path is operative to receive paper after it has passed through the transfer zone and information has been transferred to the first side of the paper. As the paper travels along the second paper path, it is turned over and then returned 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.
