Hey guys I see there is already a thread running on this issue but it's a couple of years old and there was never a solution posted so I thought I'd ask the question again.
I have a Ricoh Pro C5200 which brings up SC665-04 error codes intermittently, sometimes several times a day. Along with he error code it brings up "set the waste toner container correctly".
All indicators point to the coms between the PFB, IOB, or BICU. Any input would greatly appreciated. Thanks
