Drum Temperature Detection Circuit

The drum temperature detection circuit is composed as shown in the figure below. It converts the input

voltage from the drum thermistor into a digital signal by means of the A/D converter on the LGC board.

The drum thermistor is a device whose resistance value is smaller when the temperature is higher.

Therefore, when the temperature becomes higher, the input voltage to the A/D converter becomes

Drum thermistor-Y

Drum thermistor-K
