(6)Temperature detection configuration

Thermistor is a device whose resistance decreases as it detects a higher temperature. Thus its input voltage to CPU changes and then CPU judges whether this change is normal or abnormal. If one of the fuser roller thermistors is broken, the control circuit judges that the fuser roller tem- perature is extremely low and keeps turning the IH coil ON. As a result, the fuser roller tempera- ture rises, and possibly activates the thermostat which is a safety protection device. To prevent this in advance, CPU works to detect whether each thermistor is broken or not.

Also, the thermistors constantly check the temperature of IH coil to prevent it from excessive heating by IH circuit abnormality, LGC circuit abnormality or thermistor abnormality. The therm- istors automatically turn OFF the power when the temperature of IH coil exceeds the specified temperature.
