(6) Fusing
When passed between the heat roller and the backup roller, the toner image transferred to
the paper is fused into place by the application of heat and pressure to it.
The Teflon coated heat roller is heated by the built-in heat roller of 800W/backup roller of
500W (halogen lamp). The fusing temperature is controlled by the sum of the temperature
detected by the thermistor moving over the surface of the heat roller and the temperature
detected by the thermistor moving over the surface of the backup roller. A thermostat, which
is provided for safety, becomes open by a heat roller temperature rise of not less than fixed
degrees and cuts off voltage supply to the heater. The backup roller is being pressed against
the heater by the pressure springs on both sides.
