Remove the fuser and the plates below, You will find a PCB with a shutter mounted on it which is operated by a solenoid.
The foam noise dampener on the solenoid breaks down and becomes sticky and causes the solenoid to stick.
Scrape off the foam and put a small piece of electrical tape in it's place.
Problem solved

BTW, i found this dust on the belt, can I order only the belt or only the whole module is sold

[Dickie]

You can only order complete belt assembly but I doubt it is that that is causing the problem, I have had these belts do 3-4 times their life and still not cause a problem
