Abstract
A system and methods for controlling the fuser heater of an electrophotographic imaging device, including initiating a preheating operation for preheating the fuser heater. Following a temperature of the fuser heater reaching a first predetermined temperature during the preheating operation, heater power is calculated based on a current temperature of the fuser heater and upon a second predetermined temperature. Current line voltage of a power supply line powering the electrophotographic device is also calculated, and a maximum heater power is determined based on the calculated current line voltage. The calculated heater power is then compared with the determined maximum heater power and the fuser heater is powered using the heater power equal to a lesser of the calculated heater power and the determined maximum heater power to heat the fuser heater from the first predetermined temperature to a second predetermined temperature.
