4. Fuser Lamp Drive Circuit
It consists of 2 Fuser Lamps and each Fuser Lamp is controlled by two HTC PC Boards.
The Fuser Lamp is powered by 100 VAC. When the CN765, Pin 6 (nSSR) on the HTC PCB goes LOW,
the Fuser Lamp turns ON. This lights up the PC101 LED and activates the SCR101 photo-triac, and
100 VAC is sent to the Fuser Lamp.
