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.
Heater
Comprises two parts
Number of watts of heater:
MP C4504/C5504/C6004 MP C3004/C3504
NA/TWN EU/AA/CHN NA/TWN EU/AA/CHN
Center 809W 816W 809W 700W
Edge 430W 679W 430W 527W
Nip pad
Presses against the Pressure roller to form a fusing nip. The top surface is covered with a slippery
sheet.
Reflector
Transmits heat efficiently to the left of the Fusing belt.
Shield
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).
Flanges
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.
Temperature Control (MP C4504/C5504/C6004)
To prevent excessive edge temperature rise when printing small size paper, the light-up pattern of the
center/edge heaters and shield plate position are changed depending on the paper size.
