No central site that I've ever found. My only recourse has to been purchase of the technical manual from the mfg.
But trying to fix one that has been out of production for a while is a pain. I'm lucky in that I have a contact that is a printer warranty repair station, so I can get info and parts that are not generally available to the public. Ed Fair
