ABSTRACT:
A fuser assembly comprises a fusing member and a pressure member, where the fusing member and the pressure member cooperatively rotate to form a fuser nip. The fuser is arranged so that the pressure member speed is reduced with respect to the fusing member speed, thus forming a reduced pressure member speed. The reduced pressure member speed stretches or retards the surface of the fusing member elastomer enough to assist in stripping or peeling the media sheet lead edge from the fusing member. As a result of initially stripping or peeling the media sheet lead edge, the remaining media body likewise is assisted to be stripped or peeled from the fusing member. In various embodiments the media stripping or peeling process is assisted by means of one or more air knives, one or more stripping fingers, or any combination of these items.
