I don't know if anybody will know the answer to this but I can't find any better forum to post this on. We have a Ricoh 3700L which does not pickup any calls when dialed. It just keeps rining. the machine can send faxes fine, but just never picks up when it receives one. I've forwarded the DN onto another fax machine and that fax receives the calls for this machine fine, so obviously the problem is with the machine itself. Does anybody have any idea what may cause this, is it something simple or is it a hardware problem?
