• Because there is a danger of burns on contact with hot parts of the fusing unit, start work when the temperature drops to a low enough temperature.
  • To clear SC544-02 or SC554-02, replacing the fusing unit or installing a fuse (provided in the fusing sleeve belt unit) in the fusing unit must be required. Refer to "How to cancel SC544-02/SC554-02 with a new unit detection fuse" in "Fusing Sleeve Belt Unit".

    Clearing SC544-02 or SC554-02 when Replacing the Fusing Unit

  1. Install the new fusing unit. (The machine detects the new unit, so a unit previously installed on another machine cannot clear SC544-02 and SC554-02.)

  2. Execute SP5-810-002 [SC Reset: Hard High Temp. Detection]. *SP5-810-002 [SC Reset: Hard High Temp. Detection] is new SP.

  3. The fusing unit features the new unit detection function, so it is not necessary to reset the PM counter manually when replacing the fusing unit and dust filter together.

    The dust filter’s PM counter will also be reset.

    When replacing only the fusing unit, perform SP3-701-116 [Manual New Unit Set: #Fusing Belt].

  • When the fusing unit is used past its target yield (400k), the fusing unit may break, causing a service call. Therefore, the machine displays a warning on the operation panel at 415k pages and stops at 430k pages.
