"Hi, I have an HP LaserJet Pro M402dne. When I turn it on, the fan starts spinning for a few seconds, but then I hear a loud 'double click' or grinding noise (clack-clack sound). Immediately after this sound, the fan stops spinning and the printer stays idle.

​I suspect it might be a stuck solenoid or a fuser gear issue, but I’m not sure. What is the most likely cause for this specific 'double click' sound on startup, and how can I fix it?

​Thank you!"
