ABSTRACT:
An apparatus for providing tension to a photoreceptor belt mounted for rotation about a plurality of fixed rollers mounted to a frame of an imaging device comprises a tensioning roller having a longitudinal axis and a convex contact surface for forcing a wrap angle with an inner surface of the photoreceptor belt, a moment arm mounted at a first end to the frame for pivotal movement relative to the frame about a pivot axis fixed relative to the frame and mounted at a second end to the tensioning roller; and a force exerting mechanism mounted to the frame and coupled through the moment arm to the tensioning roller to provide a force perpendicular to the longitudinal axis of the tensioning roller, the force exerting mechanism being configured to increase the force exerted thereby as the length of the photoreceptor belt increases.
