2.1.3.10 Fusing
In the fusing process, toner is fixed on a paper with heat and pressure.
PRINCIPLE OF FUSING
The toner image on the paper, which is transferred from the belt, is fixed by the heat
from the heaters inside the heat roller and pressure roller and the pressure of these two
rollers.
Figure 2-24. Principle of Fusing
FUSER UNIT
Heat Roller
Applies heat to fix the toner to the paper.
Pressure Roller
Applies heat and pressure to fix the toner to the paper.
In addition, a high positive voltage given to the roller surface supports the paper to
attract the toner firmly to prevent it from flying off during the fusing process.
Peeling Board
Peel the paper off the heat roller to prevent the paper from sticking around the
roller.
Heater
Both the heat roller and the pressure roller include a halogen heater inside of
themselves. The halogen heaters, which seals a heating coil in it, raise the
temperature of rollers to a certain level to fix the toner.
Thermistor
Monitors the temperature of the roller surface. When it detects an abnormal high
temperature, the power supply to the heaters is cut off.
Thermostat
When the temperature of the heat roller and pressure roller rises to a certain level,
the thermostat closes the circuit of the heater.
