4. Heater lamp control circuit

A. Outline

The heater lamp control circuit detects the heat roller surface temperature and converts in into a voltage level, which is inputted to the CPU analog input
pin.

The CPU converts the analog voltage into a digital signal level and compares it with the set value of the simulation to turn on/off the heater lamp

according to the level, maintaining the heat roller surface temperature at a constant level.

The lower the heat roller surface temperature is, the greater the thermistor resistance is, and vise versa.

Therefore, the lower the heat roller surface temperature is, the higher the thermistor terminal voltage is, and vise versa. The thermistor terminal voltage
is inputted to the CPU analog port.

The CPU controls ON/OFF of the heater lamp by this input voltage level.
