Claim:
1. A method for controlling a fuser heater of a fuser assembly for an electrophotographic device, the method comprising: determining, by the electrophotographic device, an initial temperature of the fuser heater; calculating, by the electrophotographic device, a plurality of warm-up times for heating the fuser heater to a first predetermined temperature based on the initial temperature, and a plurality of previously determined warm-up times stored in memory of the electrophotographic device, the previously determined warm-up times being taken over a plurality of line voltages; determining, by the electrophotographic device, an actual warm-up time for heating the fuser to the first predetermined temperature from a second predetermined temperature less than the first predetermined temperature; selecting, by the electrophotographic device, a first calculated warm-up time and a second calculated warm-up time from the plurality of calculated warm-up times, the first calculated warm-up time is a smallest calculated warm-up time that is greater than the actual warm-up time, and the second calculated warm-up time is a largest calculated warm-up time that is less than the actual warm-up time; determining, by the electrophotographic device, a first line voltage value corresponding to the first calculated warm-up time, and a second line voltage value corresponding to the second calculated warm-up time; calculating, by the electrophotographic device, a current line voltage based on the actual warm-up time, the first and second calculated warm-up times, and the first and second line voltage values; and controlling an operation of the fuser assembly based upon the calculated current line voltage.
