  • Photoreceptor belt tracking apparatus employing an actuated edge guide system and low lateral force rollers
    Publication number: 20030076405
    Abstract: A system and method for tracking belts disposed on rollers in a photoreceptor apparatus. The system includes a movable, belt edge guide that operates in combination with an encoder, a belt edge sensor, a belt hole sensor for detecting a hole in the belt surface, wherein the profile of the edge of the belt is learned as a function of the belt position on the rollers. The encoder and belt hole sensor are used to actuate the edge guide system to compensate for the contours of the belt edge and to maintain a constant lateral position of the belt at any given point on the belt.
