Overheat Protection
If the hot roller temperature becomes greater than 245 °C, the CPU cuts off the power to the fusing lamp.
At this time, SC543 will be generated.
If the thermistor overheat protection fails, there is a thermostat in series with the common ground line of the
fusing lamp. If the temperature of the thermostat becomes greater than 210 °C, the thermostat opens,
removing power from the fusing lamp. At this time, the machine stops operation.
