Abstract
An apparatus includes a photoreceptor belt, a fixed transfer roller positioned on the inside of the photoreceptor belt, and a movable transfer roller positioned on the outside of the photoreceptor belt. The fixed transfer roller and the movable transfer roller are positioned to form a nip, and the photoreceptor belt and a web of print media are positioned in the nip. Also, a support roller and a compensation roller contact the web of print media. The support roller is positioned between the compensation roller and the nip. A physical link is connected to the support roller and the compensation roller. The physical link moves the support roller and the compensation roller so as to keep a constant tension on the web of print media.
