A fuser system of a xerographic device, including 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 having a nip width between the
fuser member and the pressure member, wherein the nip width is set to
within a specification nip width range, a drive system for driving said
fuser member relative to said pressure roll; a sensor for monitoring the
torque of said drive system; a processor in communication with the sensor
that receives torque data from the sensor, wherein the processor
determines a current nip pressure uniformity from the torque data and
compares the current nip pressure uniformity to the specification nip
pressure uniformity range, and a nip pressure adjustment device in
communication with the processor, which adjusts the current nip pressure
uniformity to be within the specification nip pressure uniformity range.
