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.
