Remark:
During warming-up before the pressure roller lamp is turned ON, the center and side heater
lamps are turned ON to raise the surface temperature of the fuser belt. When the pressure roller
lamp is ON, the equipment is in ready or printing status, each heater lamp is turned ON/OFF
alternately to maintain the surface temperature of the fuser belt at a certain level (setting temper-
ature of each status).
