Hello,
I have problem with machine Ricoh Aficio MP 6500, this morning appears SC 670. In service manual I saw that is the BCU board in question, I enered the service mode then swiched the machine off than on, but nothing. I tried to reconnect all cables on BCU board but nothing, i turned the machine on, again the same thing. The mashine restarts . Then apear the SC 818, I saw in service maual that can be:
System program defective
Controller board defective
Optional board defective
And again restarts
Whan can I do else?
