Unfortunately, I only worked on Xerox equipment for a few years, so I'm not sure what to do next. The 7XXX machines I initially worked on were somewhat troublesome to change developer on, but that machine appears newer than what I've seen so I don't know. Hopefully somebody smarter than me will help you out if you still need it.
