The model of 35 cpm or below require little amount of heat, so it controls the temperature by the

soaking plate and heater control at the edges and center.

The soaking plate on the nip (on the surface of the pressure pad) disperses the temperature

deviation between the front and rear parts of the fusing sleeve, so as to even out the temperature.

A Fusing belt is driven by drag rotation following a Pressure roller, and presses a Nip pad against the

Pressure roller to fix toner on the paper.

The heater emits light, and a point on the left of the Fusing belt which is heated moves in an

anticlockwise direction so that heat is transmitted up to the contact point with the Pressure roller.

Comprises two parts

Transmits heat efficiently to the left of the Fusing belt.

Shield width changes by rotating the shield according to the paper width. Ensures that light from

the heater is not transmitted to the Fusing belt edge (prevents excessive edge temperature rise when

printing small size paper).

Situated on both ends of the Fusing belt. They maintain the shape of the belt.

Soaking plate

Disperses a temperature deviation in a longitudinal direction of the Fusing belt to uniformize.

To prevent excessive edge temperature rise when printing small size paper, the light-up pattern of the
