4.13.6 FUSING SLEEVE BELT UNIT
The fusing sleeve belt unit is designed with a highly soft material. Do not touch the sleeve belt unit with your hands to prevent dents during replacement. If you have touched it and a dent has been made, the dent will gradually become larger during operation and it can cause a fusing malfunction or sleeve belt breakage.
To cancel SC544-02/SC554-02, it is necessary to replace the fusing unit or install an intact new unit detection fuse. Refer to page 6-224 "When SC544-02, SC554-02 (Non-contact Thermistor High Temperature Detection) Is Displayed".
If you are replacing the fusing sleeve belt unit for PM or any reason other than canceling SC544-02/SC554-02, you can discard the fuse that is packed with the new fusing sleeve belt unit.
Adjustment before Replacing the Fusing Sleeve Belt Unit
Before replacing the fusing sleeve belt unit, set SP3-701-116 to "1" and switch the power OFF. Then replace the fusing sleeve belt unit and switch the power ON.
