ABSTRACT:
A heat and pressure fuser and RAM system therefor. A rotating wick is provided in one disclosed embodiment which cooperates with a metering roll to apply silicone oil release agent to the surface of a heated fuser roll. To this end the rotating wick contacts silicone oil contained in a sump and through its rotation conveys the oil to the metering roll which in turn applies a metered quantity of oil to the surface of the heated fuser roll. In another embodiment, a rotating wick together with a metering roll and a donor roll serve to convey silicone oil from a supply of oil to the surface of the fuser roll.
