Kyocera 6052 ci with Error c7911

[chester]

I am getting an error c7911 which is related to the black developer eprom.
Having replaced the black developer unit twice I am now getting either a blank area where the black image should be or I get a horrendous double black image over the page.
I have also replaced the front pcb which all drum and developer units plug into.
This particular device seems a right Friday afternoon job and even my colleague who has taken a look is not sure.
Any ideas/suggestions would be gratefully received.

As i had written in another threat,
we are talking about serial communication line.
If one of the components/ Eeproms not working probably, system will stop at last point and you`ll get the communication error for this component.
See enclosed file for better understanding
