Fuser Lamp Drive Circuit
The Fuser Lamp is powered by 115 VAC. It is driven by the LVPS and controlled the FCB PC Board. When the CN32, Pin 9
(nSSR) on the LVPS goes LOW, the Fuser Lamp turns ON. This lights up the PC301 LED and activates the CR301 photo-triac,
and 115 VAC is sent to the Fuser Lamp. The time at which CR301 is actually activated depends on the 115 VAC sine wave.
When the cross-voltage for Pin 6 and Pin 4 of PC301 is other than 0 Volts (sine wave exceeds 0 volts), PC301 inhibits the
activation of the triac and turns ON the Fuser Lamp.
