• A belt fusing system is used. This has a faster warm-up time than a conventional

hot and pressure roller system.

• The heating roller is made of aluminum to increase the temperature of the fusing

belt quickly.

• The hot roller is made of sponge, which flattens slightly, also increasing the

fusing nip. This roller does not contain a fusing lamp.

• Each of the heating and pressure rollers has a fusing lamp.

– NA: 770W for the heating roller. 350W for the pressure roller

– EU: 700W for the heating roller. 325W for the pressure roller

• The heating roller thermistor and pressure roller thermistor control the

temperature of these lamps.

• Temperature is normally controlled by turning the fusing lamps on and off. SP1-

104-1 is used to change between on/off control and phase control

• The oil supply roller supplies a small amount of oil to the pressure roller through

the cleaning roller. Oil does not need to be supplied to the oil supply roller

because it contains oil and the amount of oil supplied to the pressure roller is

small.
