Fusing Lamp Control
When the main switch is turned on, the machine turns on the fusing lamp
and raises the fusing temperature to 80 °C in about 6 s. For printing, the ma-
chine raises the fusing temperature to 185 °C.
When the power saver timer expires, the machine goes into a power saver
mode. In Level 2 Power Saver Mode, the fusing lamp is turned off. For Power
Saver Mode Level 1, the user can select whether to keep the fusing lamp off,
or at 80 °C or at 145 °C.
Cross Reference:

If the printing operation continues for more than 3 minutes, the machine
