MX-2700n with F2-67 code
Hello, I have this code on this machine. The drum and developer is turning. The toner motor is working and the toner pipe is not clogged. I think it is some kind of charge issue. The yellow drum is coated in toner. If I switch the drum units around it will clean up and whichever drum unit that is in the yellow position will get coated. So I dont think it is the coronas. It seems like it has to be one of the HV boards. Seeing if anyone has any suggestions or help. Thanks

Re: MX-2700n with F2-67 code
I would try a new yellow toner cartridge first (bad CRUM?). If that doesn't do it I would try a yellow developer unit next. The density sensor may have whacked out and is over toning. I would then check the HV contacts (Sharp uses springs and wires for contacts?????). Do all of these before ordering an HV PWB. It will save you some $$$.
