bizhub 350 faxing 0x0000999a

bizhub 350 sits there and it aborts. either faxing or printing it will just abort. I replace the mfbs board. that did not fix
I initialized then did a total reset. nothing. I have the fax board disconected. it still did it. the service book is not
really clear but it said replace the mfbs board and the fax board. any thooughts>?
I think the code I stated is correct. hard to make it do it and record the code. thanks
