ABSTRACT:
A fuser system of a xerographic device has a fuser member and a pressure member in which the pressure member is made to exert pressure upon the fuser member so as to form a nip. A drive system drives the fusing member and/or pressure member. A sensor monitors torque of the drive system, and a processor in communication with the sensor receives torque data from the sensor. The processor determines if the torque exceeds a predetermined value, wherein the drive system holds the fuser member and the pressure member in a partially loaded state when the torque exceeds the predetermined value.
