The figure illustrates a paper path that may provide an automatic duplex feature to an automatic reproducing machine. A sheet of paper 10 is fed from paper tray 12 b means of segmented feed roll 14 into a chute 16 wherein

developed image on a photoconductive belt 20 supported between support rolls 22 so that the toner image may be transferred from the surface of the belt 20 to the copy paper 10 by transfer corotron 26. After transfer, registration feed rolls 18 continue to feed the paper in a forward direction around inverting ring 24 until the lead edge comes into contact with transport rolls 28 which transport the paper toward chute 34. The trailing edge of the copy sheet as it passes through rolls 30 is sensed by sensor 32 at which time the direction of motion of the rolls is reversed and the copy paper is fed back from the chute 34
into a sheet gripper mechanism 25 which transports the sheet back into the transfer position so that the second image may be transferred on the opposite side of the copy as the first image. In the second pass around the inverting ring 24, the copy sheet 10 is transported completely through the rolls 30 and collected in tray 36. Following transfer of the image from the photoreceptor belt to the copy paper and before making the duplex side the image may be fixed to the copy paper in any suitable manner...
