Abstract
A photoreceptor belt control apparatus for a printer having a photoreceptor belt that circulates around rollers rotatably installed on a belt frame. The apparatus includes a pair of auxiliary frames slidably and pivotally installed on the belt frame, and a steering roller whose ends are rotatably installed respectively on the auxiliary frames. The steering roller rotates in contact with the photoreceptor belt. A shaft is rotatably installed on the belt frame, and a cam unit is installed on at least one end of the shaft for controlling the inclination of the steering roller by pivoting each of the auxiliary frames according to the rotational position of the shaft. A tension control unit controls the tension in the photoreceptor belt by sliding the pair of auxiliary frames.
