Hi Bros,

I have a problem on FX DCV7080 that suddenly appear error message "Toner Fault". After restarting the copier is still working normally, but then the error appears again. I was changed some parts like Toner chip, Hopper, Deve unit, ESS pwb, MCU pwb and ROMs from another copier and I also Factory reset. But the trouble is not resolved.

How to reset this trouble, i need yours hepl!
