2.2.3.4 Fuser
It is consisted of a halogen lamp, heat roller, pressure roller, thermistor and thermostat. It sticks the toner on
a paper by heat and pressure to complete the printing job.
1) Thermostat
When a heat lamp is overheated, a Thermostat cuts off the main power to prevent over- heating.
- Thermostat Type : Non- Contact type dual THERMOSTAT
- Control Temperature : 170℃ ± 5 ℃
2) Thermistor
It is a temperatrue detecting sensor.
- Temperature Resistance : 7 ㏀ (180 ℃ )
3) Heat roller
The heat roller transfers the heat from the lamp to apply a heat on the paper.
The surface of a heat roller is coated with Teon, so toner does not stick to the surface.
4) Pressure roller
A pressure roller mounted under a heat roller is made of a silicon resin, and the surface also is coated with
Teon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface of a
paper permanently.
5) Halogen Lamp
- Voltage 120 V : 115 ± 5 %
220 V : 230 ± 5 %
- Capacity : 600 Watt ± 25 W
