mp 2852 sc 670 error

[alvin_3000e]

Hi,

I have a ricoh mp 2852 giving sc 670 error. I have replaced a new controller board and still same error.
On checking ricoh error message code in service manual, it shows either controller board or bcu board issues.
But on chats forum its shows the problem could be ipu board problems with the chips.
I am not sure if I should order another ipu board or bcu board to solve the problems.
Any advise will be greatly appreciated.
Thank
alvin

Unfortunately, there's not a single solution for many SC codes, and this one is one of the most frustrating (SC670/672)
I've resolved it more than once by simply re-seating the controller board, other times controller replacement was necessary.
I know of others that have found found that removing/ replacing the fax unit fixed it, but yes, it could also be a bad BICU or IPU.
Unfortunately, it's a trial and error situation

Try it with the harddrive disconnected.

Before you replaced the controller did you do any other trouble shooting? updating firmware for example?

yes, I had one that replacing the hdd and updating the firmware took care of it.
