Theory of Operation
Rated Output Power
Fuser AC Power Control
The Fuser receives heat from AC power, which 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 photo triac. In other words, the AC control part
is passive circuit, so it turns the heater On/Off while retrieving signal from the
engine controller.
When the heater On signal is turned On at the print engine, the LED of PC51
(photo triac) measures the voltage and flashes. From the flashing light, the
triac part (light receiving part) measures the voltage, and the voltage is
supplied to the gate of triac and flows into the triac. As the result, the AC
current flows in the heat lamp, and heat is generated.
When the signal is Off, the PC51 is Off as the voltage is cut off at the gate of
Triac. When the triac turns Off, the lamp is turned Off.
