Fusing Lamp Control
During printing, the machine keeps the fusing temperature at 190
°
C. If the printing
operation continues for more than 3 minutes, the machine keeps the fusing
temperature at 165

When the Energy Saver Key is pressed or the energy saver timer expires, the
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
°
C.
