ABSTRACT:
A multi-color electrophotographic printing machine in which the tangential velocity of the photoconductive drum in the transfer zone is greater than the tangential velocity of the transfer drum having the sheet receiving the transferred images thereon. A buckle is formed in the sheet after the transfer zone, resulting in the sheet being tacked to the developed image on the photoconductive member and moving at the same tangential velocity as the developed image. This is achieved by a transfer sheet having one end secured fixedly over an aperture in the transfer drum. The other end of the transfer sheet is resiliently secured to the transfer drum. The sheet of support material receiving the transferred images is secured at the leading edge to the transfer sheet. In this way, the transfer sheet and the sheet of support material may be induced to form a buckle after the transfer zone enabling the sheet of support material and the developed image to move at the same tangential velocity. By moving at the same tangential velocity, the image smear is eliminated during transfer.
