IR Adv 6055 with E808-0004

[dohha]

I have IR Adv 6055 with E808-0004 ,if this machine powered off for a few minutes , the error code disappeared
and I can reuse it again for some hundreds of pages then the same error , E808-0004 back again
I think the main driver pcb is ok
this machine has about 1.5 millions copies on it, and from 2 months I had replaced upper fuser roller and cleaning web
any help will be appreciated
thanks

have you checked the connectors on the back of unit 1 and on the frame?
IH Power supply is always a possible suspect as well

re:
I already checked all connectors of the fixing unit and it looks ok

Already had similar problem on ira 8095.
Mr. Teckat helped me to resolve error.
He said :,, I would check wall voltage supply ,especially proper ground-from Neutral to Ground =0v>0.5v max.
Poor ground effects Fix Temp .,,
I dont believe my eyes when my multimeter read about 20-25V from ground to neutral.
After that check main Thermistor.
