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.
• After the PM counter for the heating roller has reached its PM life (300K pages), the machine stops
the operation automatically. Replace the heating roller before the machine stops its operation (stop
warning: 315K pages, stop: 330K pages).
• Change the setting of SP3-902-018 from "0" to "1" before replacing the heating roller. Otherwise,
the machine will not recover.
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 sleeve belt unit 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 sleeve belt unit 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.
