I do a lot of numbering on my machine (Ricoh c900) and for no apparent reason it decided to stop making master files in VDP. When I attempt to make the master, I get the error that the connection to the c900 has been lost, and no other explanation. I have tried clearing out any cache I can and no luck. The Ricoh techs are baffled and when I called EFI for support, they wouldn't tell me a thing unless I wanted to buy a separate service contract through them. Not at all impressed, but I still nedd to fix this problem. Has anyone else encountered this or know how to fix it?
