PREVENTIVE MAINTENANCE (PM)

* L3, L4: Pressure roller thermistor
Clean the thermistor with alcohol if the toner or dirt is sticking to it when the fuser belt is replaced.
Do not deform or damage the thermistor during the cleaning. Replace the thermistor with a new
one if it is damaged or deformed regardless of degree.
* L11: Separation plate
If toner adheres to the separation plate, wipe it off with dry cloth.
Do not take off the separation plate unless otherwise required.
* L13: Fuser unit gear (tooth face and shaft)
Wipe off any old grease, and then apply 3 to 4 rice-sized grains of white grease (Molykote HP-
300) onto the gear teeth and shafts.
* L14: Fuser unit gear (tooth face)
Wipe off any old grease, and then apply 3 to 4 rice-sized grains of white grease (Molykote HP-
300) onto the gear teeth.
Note:
Since the one-way clutch is pressed into the gear (GEAR-8H40-FMR) that is attached to the shat
of the fuser roller, apply grease on the tooth face only. Do not apply grease on the shaft.
* L15: Fuser belt thermopile
Take off the fuser belt thermopile from the equipment and wipe off the dirt using a cloth with a
small amount of alcohol. Do not touch the lens of the thermopile by hand. Clean the thermopile at
the timing shown below.
