[A]
The fusing unit has two fusing lamps: the first fusing lamp (center: 650W) [A] heats
the center of the fusing roller, and the second fusing lamp (ends: 550W) [B] heats
both ends of the hot roller. This arrangement ensures even heat on all surfaces of
the roller.
In order to control the temperature of the roller, two high response thermistors are
attached to the unit, one near the center [C] and one at the end [D] of the hot roller.
