- 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 When SC544-02, SC554-02 (Non-contact Thermistor High Temperature Detection) Is Displayed.
- The fusing unit has a new unit detection mechanism, so it is not necessary to set SPs (New Unit Detection) when replacing an old fusing unit.
- 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.
