Hello friends, I have a problem with a Ricoh MPC6503 that's giving an error SC626-01. It speaks about the drawer unit board DUB. I have replaced the DUB and also I have checked all wires in the drawer unit to see if there is a short but yet I keep getting this error. There is a bulletin on the MPC6502 about this error, that mentions a wire shorting just behind the paper transport unit. I have checked these wires and others but cant seem to find anything that would cause this error. Any help will be much appreciated.
Thanks
Thanks
