When replacing a gear individually or at the 600K PM, apply grease to reduce the wearing of the gears in the fusing drive gear train and to prevent abnormal noise (Grease: Fluotribo MG).

  1. Apply the grease to the pressure roller gear [A] and the small diameter of the two layers gear [B] while rotating the pressure roller gear [A].
  2. Check that the grease is applied to all the gears in the gear train (whole circumference and full width).
Pressure Roller Gear: Grease Amount ([A]: lower limit, [B]: upper limit)

Coaxial Gears: Grease Amount ([A]: lower limit, [B]: upper limit)
