* 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
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.
Notes:
Since the one-way clutch is pressed into the gear (GEAR-8H40-FMR) that is attached to the
shaft of the fuser roller, apply grease on the tooth face only. Do not apply grease on the shaft.
