4.11.2 FUSING UNIT
 Turn off the main switch and wait until the fusing unit cools down before beginning
any of the procedures in this section. The fusing unit can cause serious burns.
1. If you will replace the heating roller or pressure roller in the fusing unit (at PM for
example), then reset each counter.
 Set SP 3902-018 to "1" for the heating roller replacement.
 Set SP 3902-019 to "1" for the pressure roller replacement.
 If you do this, then the machine will reset the PM counter for the heating roller or
pressure roller automatically, after you turn the power on again.
 It is not necessary to clear the PM counter for the fusing unit with SP mode when
you replace the fusing unit. This is because the fusing unit has a new unit
detection mechanism.
2. Turn off the main power switch.
3. Open the right door.
