Abstract
Roll fuser apparatus and a release agent management system therefor. The fuser comprises a pair of pressure engageable rolls one of which is heated and has a relatively thick silicone rubber outer layer. The fuser is adapted to accommodate various size copy sheets resulting in a number of areas of the silicone rubber undergoing physical changes due to the effects of sheet edge contact therewith. The release agent management system is designed to minimize the adverse effects caused by the sheet edges contacting the silicone rubber outer layer. To this end the system which serves to dispense silicone oil onto the surface of the silicone rubber is provided with a plurality of apertures which are strategically located such that a quantity of the oil is introduced into the silicone rubber in these areas of sheet edge contact whereby the adverse effects noted are counteracted.
