Overheat Protection
If the hot roller temperature becomes greater
than 235°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
are thermostats in series with the common
ground line of the fusing lamp. If the temperature
of a thermostat becomes greater than
approximately 175°C, the thermostat opens,
removing power from the fusing lamp. At this
time, the machine stops operation.
