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

The sensor switch may be defective... or, the circuit board it communicates with, perhaps, is sensing or giving false indications (- that can happen, too.)

But, try turning Off the printer. Unplug it from the power. Leave it that way for at least 2 hours, to cool off and rest/reset. Then see if that clears the sensor error.

Let me know how it turns out, what happens, and I will continue to offer assistance.
