The positioning of the fusing pressure roller relies on a small, U-shaped optical sensor (photointerruptor) paired with a crescent/half-moon actuator gear. Because this sensor operates directly adjacent to the intense heat radiation of the fuser, it experiences accelerated degradation over millions of cycles. If it burns out or accumulates thick paper dust, it can no longer trace the position of the gears. 3. Mechanical Wear or Stripped Gears
