• A belt fusing system is used. This has a faster warm-up time than a standard 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 becomes a little flat, and this increases the fusing nip. This
roller does not contain a heating lamp.
• The heating roller thermistor controls the temperature of the lamp.
