  • Patent number: 4475979
    Abstract: A method and an apparatus for transferring a toner image in a transfer zone from a photoconductor to an image carrier 15. The photoconductor is mounted on an upper part 65 of a travelling table 3. The image carrier 15 lies on an inclined feed table, and after the image carrier has been released, it is held on a transport cylinder 17 by means of gripper mechanisms and is urged against the transport cylinder by a first pressure mechanism. A second pivoting pressure mechanism and the transport cylinder convey the image carrier to a third gripper mechanism, which is displaced parallel to an inclined deposit to guide the image carrier in an upward direction via a fixing station and is then opened so that the image carrier drops into the deposit.
