Your fuser is not warming up. Try clearing with Sim code 14. If the problem comes back, one of your 2 fuser lamps is broken or your thermistor is covered with toner.

Can you please walk me through clearing the code and how to find out which fuser lamps are broken. And or how to clean the thermistor?
