ABSTRACT:
A fuser system and method for a xerographic device having improved self-stripping capabilities for a wide latitude of substrate media. The fuser system includes a fuser member and a pressure member in which the pressure member is made to exert a predetermined pressure upon the fuser member. In applying this pressure load, a nip is formed having a nip width between the fuser member and the pressure member. A predetermined creep exists during normal fusing of a substrate. A load adjustment device is provided to momentarily increase the exerted pressure as a leading edge or other portion of the substrate passes through, and/or in the vicinity of, the nip, thereby increasing the creep magnitude momentarily and improving self-stripping capabilities.
