A fuser system of a xerographic device includes at least one set of a fuser member and a pressure member having a nip width therebetween, the nip width being set to within a specification nip width range, at least one sensor for monitoring the velocity of at lease one of the fuser member, the pressure member and a media passing through the nip, a processor that receives the velocity data from the at least one sensor and that determines a current nip width from the velocity data and compares the current nip width to the specification nip width range, and a nip width adjustment device in communication with the processor, which adjusts the current nip width to be within the specification nip width range. To offset changes in nip width due to hardening/softening of a fuser member material, or to provide a means to measure nip width in order to enable fusing setpoints using multiple nip width specifications, a method for closed loop control of nip width is enabled by the fuser system.
