6.9.5 FUSING TEMPERATURE CONTROL
Components
[A]: Thermostat (Heating roller)
[B]: Thermopile
[C]: Thermistor (contact)
[D]: Thermostat: (Pressure roller)
[E]: Pressure roller fusing lamp
[F]: Thermistor (non-contact)
[G]: Ferrite roller HP sensor
[H]: Fusing belt sensor
When the main switch turns on, the CPU turns on the IH coil unit and the fusing lamp. The
IH coil unit and lamp stay on until the thermistor detects the standby temperature. Then the
CPU raises the temperature to the printing temperature.
The fusing temperature for each mode is as follows. These are set by SP 1105.
If the ferrite roller does not rotate, it will overheat. The fusing belt sensor [H] detects if the
heating roller stops rotating, and an SC occurs.
