Abstract
A system and method for controlling the fuser assembly of an electrophotographic imaging device, including determining a resistance of the fuser heater at a predetermined temperature that is less than a fusing temperature for performing a fusing operation; calculating a set point heater resistance based on the determined heater resistance, the set point heater resistance being a resistance of the fuser heater at a predetermined set point temperature; reading a line voltage to the electrophotographic imaging device at a first time; calculating heater power based on the line voltage reading and the calculated set point heater resistance; and controlling a speed of a fusing operation based on the calculated heater power.
