This machine has ITB heater inside ITB to prevent the temperature reduction of the drum surface.
The thermal reed switch inside the ITB constantly measures the ITB temperature. ITB temperature is controlled by repeating ON/OFF of the ITB heater.
Memo:
When ITB temperature is low at printing etc., ITB absorb the heat of the photosensitive drum to reduce the drum temperature. ITB heater keeps the fixed temperature
(45 deg C) and prevents the reduction of the temperature of the drum surface.
The thermal reed switch on the ITB heater detects ON/OFF of the ITB heater.
