When replacing a bearing individually or at the 600K PM, apply grease to reduce the wear of the bearings and to prevent abnormal noise (Grease: Barrierta-S552R).

  1. Remove the bearing (fusing roller). (Heating Roller, Fusing Roller, Fusing Belt)
    Remove the bearing (pressure roller). (Pressure Roller)
  2. Apply the grease to the inner surface of the bearings.
  3. Rotate the ball bearing to check that the ball bearing and the inner surface move smoothly without touching each other.
