4. Fuser Lamp Drive Circuit
It consists of 1 Fuser Lamp and Fuser Lamp is controlled by the HTC PC Board.
The Fuser Lamp is powered by 100 VAC. When the CN766, Pin 2 (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
AC is sent to the Fuser Lamp.
