2. Fuser Lamp Drive Circuit
The Fuser Lamp is powered by 115 VAC. It is driven by the LVPS and controlled by the nSSR signal from
the SC PC Board. When the CN103, Pin11 (nSSR) on the LVPS goes LOW, the Fuser Lamp turns ON.
This lights up the PC001 LED and activates the CR001 photo-triac, and 115 VAC is sent to the Fuser
Lamp. The time at which CR001 is actually activated depends on the 115 VAC sine wave. When the
cross-voltage for Pin 6 and Pin 4 of PC001 is other than 0 Volts (sine wave exceeds 0 volts), PC001
inhibits the activation of the triac and turns ON the Fuser Lamp.
