Abstract: A dynamic registration device for a mailing system that reduces the problems of dust generation, ink smearing, and print head contact is provided. The biasing force normally applied to the back panel of a mail piece, such that the front panel maintains contact with a registration plate, is controlled by an actuator such that the force can be removed when the printing module is not performing the actual printing process. Thus, the biasing force can be applied only when the print head is actually printing and the biasing force can be removed once printing has been completed. In other embodiments utilizing multiple printing modules, when one of the printing modules is inactivated, the biasing force can be removed, and the mail pieces pass through the inactive printing module without being registered against the top registration plate.

Abstract: A top registration transport mechanism and method for a mailing machine is provided. The transport mechanism includes one or more displaceable rollers that have a diameter larger than the drive/idler rollers. A semi-elastic belt is looped around the drive/idler rollers and displaceable rollers. The larger diameter of the displaceable rollers causes a portion of the transport belt in the area of the displaceable rollers to be slightly raised. The registration plate can contact the raised portion of the belt to displace the belt and displaceable rollers, thereby ensuring that very thin mail pieces can be effectively processed by the transport. As thicker mail pieces traverse the transport, the displaceable rollers can be further displaced before the entire transport mechanism must be displaced to maintain registration of the mail piece against the bottom of the registration plate.
