ABSTRACT:
A method for extending the operating life of a fuser used in an electrophotographic imaging apparatus is disclosed. A control algorithm monitors the number of substrates processed over the lifetime of the fuser and adjusts the fusing temperature of the fuser to compensate for changes occurring in the nip forming members of the fuser. The useful lifetime of the fuser is extended while fusing quality is maintained. A corresponding fuser assembly is also disclosed.
