I need to recall common RICOH printer errors. The SC67310 might have specific issues. Let me check if SC67310 is a common error code. Wait, sometimes in RICOH printers, SC numbers are supplementary codes. Maybe SC67310 is part of a longer error code. For example, sometimes the main error code is followed by a supplementary code. For instance, if the main code is E03, the supplementary might be SC67310. Or maybe SC67310 is the main code. I need to verify that.
