We had this problem recently and talked with a tech specialist and he suggested getting a fuser maintenence kit which included a new fuser and a roller. I installed this yesterday and have not had any problems since. Average cost for this kit was 95.00

The problem is the middle thermistor inside the hotroller. The hotroller is not 100% round (since its not in hard metal) so itÂ´s moving the thermistor back and forward ~0.5mm at every turn. This will sooner or later break the circuit (in thermistor or the metal parts of the thermistor). Measure the termistor, it should be somewhere about 120k ohm (50k-330k min-max) Anyway, Q3656A solves the problem.
