Thermal Control Mechanism
After machine power is turned on, the fusing lamp operates until the temperature reaches pre-rotation temperature.
Then, the hot roller rotates to heat its surface evenly and raise fusing temperature to the reload temperature.
The hot roller lamp stays on until the thermistor detects the Standby Mode [B] temperature. The lamp turns on/off to
keep this temperature. To print, the temperature is increased to the Print Mode [C] temperature.
After printing, the hot roller rotates (pre-rotation) to prevent overshooting after printing.
