Fuser
The Fuser consists 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.
•Thermostat
When the heat lamp overheats, the Thermostat cuts off the AC power to the Halogen Lamp to
prevent over- heating.
– Thermostat Type: Non- Contact type THERMOSTAT
–Control Temperature: 190
°C ± 5° C (374°F ±10° F)
•Thermistor
The Thermistor is a temperature detecting sensor.
– Temperature Resistance: 7k ohms 180
°C (356° F)
• Heat roller
The heat roller transfers the heat from the lamp to apply heat on the paper.
The surface of the heat roller is coated with Teflon, so toner does not stick to the surface.
• Pressure roller
A pressure roller mounted under a heat roller that is made of a silicon resin, and the surface also is
coated with Teflon. When a paper passes between a heat roller and a pressure roller, toner
adheres to the surface of a paper permanently.
