FUSER AC POWER CONTROL
Fuser(HEAT LAMP) gets heat from AC power. The AV power controls the switch with the Triac, a
semiconductor switch. The ‘ON/OFF control’ is operated when the gate of the Triac is turned on/
off by Phototriac. In other words, the AC control part is passive circuit, so it turns the heater on/off
when recieving signals from the engine control. When the ‘HEATER ON’signal is received at the
Engine, The LED of PC102 (Photo Triac) takes the voltage and flashes. From the flashing light,
the Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of Tri-
ac and flows into the Triac. As a result, the AC current flows in the heat lamp, and heating occurs.
On the other hand, when the signal is off, the PC102 is off, the voltage is cut off at the gate of the
Triac. The Triac switches off, and then the heat lamp is switches off.
