16. Thermistor
 This thermistor is above the laser unit. It detects the temperature inside the
machine. If it becomes higher than 52 degrees C, printing stops. Then when it
falls below 50 degrees C again, printing will restart. This operation is necessary
because of the lack of cooling fans in this machine.
