The thermistor is a temperature-sensing resistor that touches the fuser roller. If it becomes coated with toner, dust, or paper fibers, it sends inaccurate temperature readings to the control board. When the MCU detects a discrepancy between the expected temperature and the actual reading, it triggers code 043-343. Open the right-side or front cover (depending on
