6. Fusing belt
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.
Each new fusing unit contains a fuse. A short time after a new fusing unit is installed, this
fuse blows. When this occurs, the machine detects that a new fusing unit is installed.
