Fusing Lamp Control
During printing, the machine keeps the fusing temperature at 170

machine goes into an energy saver mode. In Level 2 Energy Saver Mode (2-watt
Energy Saver Mode), the fusing lamp shuts off. For Energy Saver Mode Level 1,
the user can select whether to keep the fusing lamp off or at 80
°
