ABSTRACT:
In a xerographic printer including a fuser having a heating element, a first predetermined power level is applied to the heating element. The voltage associated with the heating element is measured, yielding an output code which is applied to a look-up table. The output of the look-up table relates to power to be applied to the heating element in a time interval T going forward: the output sets forth what power level is to be applied to the heating element for a smaller interval t within interval T, and what power level is to be applied to the heating element for the balance of the interval T.
