Error sc995 when replacing controller card on aficio mp 4000

[Azharuddin]

Hi all,

I'm replacing the controller card on this model (from the old machine) for network port broken issue.
I replaced it and changed the NVRAM as well even though it's given error sc995 serial number mismatch error.
Manually entered the S.no in sp5811-000. Again it's same kindly help to resolve it.
Thanks in advance

Make sure caps lock is on when re entering the serial number.
It's also possible the firmware will need updated.
