Abstract (en)
[origin: WO9321566A1] An electrophotographic printing device for the simultneous printing of both sides of a substrate contains two printing modules (10/1 and 10/2) with appropriate electrophotographic processing means (11 to 15) which are secured opposite each other in the printing device in such a way that a conveyor channel (25) for the substrate (21) is opened between the printing modules (10/1 and 10/2). The substrate (21) is guided over conveyors in the form of pairs of rollers to that its front and/or back can be brought into contact with the appropriate intermediate substrate (14) of the appropriate printing module (10/1 and 10/2). The pairs of rollers used are the reversing rollers for the intermediate substrate (14) co-operating with a counter-roller (23) or the opposed reversing rollers (22) for the intermediate substrate (14).
