• 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.
• The heating and pressure rollers each have 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. To
change between on/off control and phase control: SP1-104-1.
• The oil supply pad supplies oil to the fusing belt through the oil supply roller. The
oil supply sub-roller spreads the oil on the oil supply roller evenly.
