Have had this problem before.Replace with the new thermastats in the RTB and replace the cooling fan thats near the fusing unit sometimes heaps of crap gets stuck in the fans and does not keep the tempreture consistant.

I could understand the fans causing potential SC545's but the SC542's come up on warm-up or recovery from one of the deeper energy saver states where the fuser is off. I've noticed the issue is exaggerated on a Monday morning at locations where the customer reduces the office temperature for economy. I'm with the solutions for increasing the warm-up time, turning AOF 'Off', I've also reduced fuser temperature targets by as much as 10C with no ill effect.
Has anyone substituted one of the lamps for a higher wattage from another model? Or simply using two of the high watt lamps?
Oh I dunno, they're fighting fit in their uniforms!
The girls, obviously!
A little too young for me. I've got daughters older than that.
NEVER ASSUME ANYTHING
Careful with that - take a good look at the filaments in the lamps - some are designed to put more heat in the center or at the ends. I've hooked them up wrong once before to where the center was heating when the ends were supposed to be and vice-versa. All kinds of intermittent SC codes.

Guys Ive had this on a MP7500 but I noticed on the SMC report the errors were happening every day between 330am and 430am when no-one was around. We tried new complete fusers and everything then we figured it was the load of the heating system switching on during winter and just loading up the electrical system. We put a timer on the power point to turn it off at 10pm then on again at 6am and it seems to have worked.
