  • Patent number: 4699503
    Abstract: In an electrophotographic information printer with a xerographic reproduction system automatic duplex printing of sheets is obtained without considerable reduction of the rate of operation in that a sheet (24) after having been discharged from a sheet supply (6, 7) is passed along a feeding path (9, 10) past an image transfer station (5) to a vertical reversing chamber (15) and therefrom fed back to the separate sheet magazine (6) having an inlet opening (23) for returned sheets positioned at the opposite end in relation to the sheet discharge opening (8). The reversing chamber (15) is integral with a sorting unit (14) in a common housing (13a), a selectively operable blocking member (19) and a reversing device (17), respectively, being disposed at the lower end of a vertical partition (40).
