Abstract
Apparatus for producing duplex copies and including a movable image receiving member for receiving first and second unfixed transferable images, an image transfer device for transferring the transferable images to the first and second sides of a copy sheet and copy sheet handling apparatus. The copy sheet handling apparatus includes a copy sheet vacuum pick-off member located adjacent to the image receiving member and a mechanism for moving the pick-off member in synchronism with the image receiving member through a closed loop path to initially vacuum contact a copy sheet in contact with the image receiving member after transfer of the first unfixed image to the first side of the copy sheet, to remove and reorient the copy sheet while the first image is unfixed, and to register the second side of the copy sheet with the second transferable image on the image receiving member at the image transfer device.
