Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

That indicates a problem with the fuser thermistor (perhaps.)

Replacement of the fuser unit, with the thermistor also, is recommended (usually the fuser includes the thermistor, though I am not sure in this particular model whether that is the usual practice. As a design fact, it would have to be very close to the fuser at least, if not an integral part of it.)
