(4) Reset circuit
This circuit detects ON/OFF of power to control start/stop of each circuit. The 3.3V voltage of the main PWB is detected by the reset IC to generate the
reset signal.
When the power voltage reaches the specified level, the circuit operations are started. Before the power voltage falls below the specified level, the
circuit operations are stopped to prevent against malfunctions.

(5) Heater lamp control circuit
a. Outline
The heater lamp control circuit detects the heat roller surface temperature and converts in into a voltage level. The converted voltage is inputted to the
CPU analog input pin.
The CPU converts the inputted analog voltage into a digital signal level and compares it with the set value of the simulation to control on/off the heater
lamp according to the level, maintaining the heat roller surface temperature at a constant level.

N.M.
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.
