Abstract
An improved intermediate belt system (ITM module) is provided, which controls the lateral motion of the belt in the scan direction of an EP printer, without the use of edge reinforcements or other attachments added to the belt. The tracking system of this ITM module is passive, and maintains roll alignment/parallelism within a predetermined tolerance while also maintaining roll conicity-end flare to a predetermined maximum diametral variation over the roll to minimize the effect of external forces on the belt walk rate. The ITM module also provides angled tracking guides near the tension roll to control the lateral position of the belt; the position of these tracking guides is adjustable at time of manufacture to achieve the desired lateral belt position.
