I have a quick question: are the system software DVD's the same for the Fiery E-43a as the Fiery E-83a? They are for the same copier series and typically the higher grade QX100 servers use the same system software dvd's as the PRO80-type servers, but before trying I wanted to ask first, because I have to reload software on the E-83a model but only have E-43a DVD's from our Ricoh technician.
