The present invention provides an image transfer section of a printer having a control system controlling the operation thereof, as well as a control system and method for controlling the operation of the image transfer section. In particular, the control system and method of the present invention ensures that horizontal and vertical registration of the card and web is attained. The control is adaptive, so as to automatically adjust to differing speeds and gear drives of the independent systems. The control system of the present invention also automatically adjusts the speed of the web take-up roll and the card drive rollers so as to match the speed of the applicator rollers, thereby eliminating the need for slip clutches in the various systems as well as guaranteeing speed matches between the independent systems. Further, since the receptor web has a plurality of horizontally spaced images printed thereon, the control system of the present invention is designed to ensure that the proper image is transferred onto the card.
