Dear all

I would highly appreciate some help. I am a copier tech, i am having error 6791: Register setting error on Bizhub C35

The machine starts and the motors start turning and after around 10 seconds the machine gives the error massage.

The service manual just says :

After the default values of AFE gain and offset are set, the
machine reads the gain and offset values again. Inconsistency
between the values that are set and read is found.

The service manual says suspected part is the MFPB i wish to know if there is some sort of fix or i just have to replace the MFPB.

​Thank you all in advance for support

Did you try re-seating the connectors on Main Board? How many copies or prints?
Stuff like this makes me Update the firmware first.

It sounds like error is internal to the mfp board (assuming you've followed the connection reseating advice in the manual with no success) meaning there's nothing you can do about it other than throw it out and replace it.
