Free-belt Fusing System
Reflector Plate
Fusing Lamp
The sleeve belt rotates freely. It is driven by the pressure roller.
The fusing pad has a low friction cover, and this allows the sleeve belt to turn
easily.
The pressure roller presses against the pad to form the nip zone, where the
image is fused to the paper by heat and pressure.
The stay holds the pad in place.
The stay has a mirrored surface facing the fusing lamp to concentrate the
energy from the lamps to the left side of the inner surface of the sleeve belt.
The temperature at the ends of the lamp is lower than at the centre.
The reflector plate prevents heat from the fusing lamp from damaging other
machine components.
