• For this model, a belt fusing system is used. This system 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 at the contact point
of the pressure roller. 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.
The oil supply roller supplies oil to the fusing belt through the oiling roller. This
mechanism applies a constant thickness of oil to the fusing belt.
