Ricoh mpc 3504 error sc547-02

Hi got 1 unit mpc 3504 showing sc 547-02. Normally what is the issues with this model, can it be the fuser unit or the power supply.
I have work on the older black and white model and not so familar with this model. Any advise where to check first. Thx

i had one recently with torn fuser belt but also the odd way the pivot the duplex gate on that unit also was broken.
It was not easy to see and they are all held together with tiny c clips.....if you have another working unit take a few pics with you...
changing the sleeve assembly was easy..like the 03

I also saw it once where it was trashy line voltage. They were using a generator. The voltage was fine but the frequency was all over the place.

Well look you.
That code has been given due to damage IN THE thermistors due to electricity problems, the solder melted....just as a senior told us previously but...I have also seen it in damage to the controller and also in IO.

Hopefully the damage is thermistors.
