Hi, I'm Robert and I'll be helping you with your printer question.
when you say smart ring are you talking about the distinctive ring that the phone company sets up for you?
Also the ring type should have nothing to do with sending of faxes only receiving. So if the sending is not working there is some other issue. The most simple would be that you have the phone line connected to the port on the fax where an extension phone goes instead of the one that goes to the wall. Can you check and make sure that it is connected properly. Also that a phone plugged into that same jack or into the extension phone port on the fax gets a dial tone.
