3. OIL SUPPLY AND CLEANING
Silicone oil is applied to the hot roller to help prevent toner and paper from
sticking to the hot roller, to reduce paper curl, and to help in roller cleaning.
A small one-way valve pump moves the oil from the oil tank [A] (capacity
oil sump [B]. The oil pump lever [C] alternately presses and

releases
rubber sleeve [D] between the valves as the oil cam [E] turns.

The felt wick soaks up oil and supplies it to the top of the oil supply pad [F].
The oil supply pad then applies the oil to the hot roller as the roller turns.
The oil blade spreads and levels the oil on the hot roller. Excess oil flows
along the blade toward the ends of the roller, and returns to the oil sump. Oil
flows out through a hole in the bottom of the oil sump and returns to the oil
tank.
The
oil supply pad both distributes oil to the hot roller and removes toner
foreign matter from the hot roller surface.
