PCT No. PCT/NL91/00151 Sec. 371 Date Sep. 8, 1994 Sec. 102(e) Date Sep. 8, 1994 PCT Filed Aug. 14, 1991 PCT Pub. No. WO93/04409 PCT Pub. Date Mar. 4, 1993Imaging apparatus for duplex printing on a substrate having first and second sides and a leading edge and a trailing edge, the imaging apparatus including a first member having an image support surface adapted to sequentially support first and second images thereon, a second member adapted to support the substrate such that one side of the substrate engages the image support surface, leading edge first, at a transfer region and transfer apparatus for transferring the first image from the image support surface to the first side of the substrate at the transfer region while at least partially fixing the image thereto. The imaging apparatus also includes a waiting station adjacent the second member for receiving the substrate after transfer of the first image thereto and prior to the transfer of the second image thereto and an output station for receiving the substrate after completion of image transfer thereto. The imaging apparatus includes deflector apparatus adjacent the second member operative to receive the substrate directly from the second member and selectably deflect the substrate towards the waiting station or the output station for delivery thereto and roller apparatus associated with the waiting station for selectably engaging the trailing edge of the substrate after the substrate has been delivered to the waiting station for delivering the substrate back to the second member. The second member is operative to deliver the substrate to the transfer region, whereat the second image is transferred to the second side of the substrate.
