    Abstract: An apparatus includes a fuser assembly including a heater member. The heater member includes at least one heating element and at least one temperature sensor to sense a temperature of the heating element. A first power control unit is coupled to the at least one temperature sensor and operative to calculate at least one power level for the at least one heating element based upon at least one set-point temperature therefor and the temperature sensed by the at least one temperature sensor. A second power control unit is coupled to the first power control unit, receives the calculated at least one power level and selects, based upon the calculated power level, at least one actual power level from a stored plurality of predetermined power levels. The second power control unit controls a power for the at least one heating element based upon the selected at least one actual power level.
