How many rings does the Sharp UX-300 Fax Machine use before picking up?

Wow thats an old fax. Try www.sharpusa.com . They may still have owners manuals listed there.

leave these phones unused for one day and then use it and see.

leaving them unused will make everything get settled.

While it is ringing, press the start button to receive a fax.

Problem is most likely caused by a worn paper pick roller. It would be more expensive to repair this fax than to just replace it.

good luck

I have a Sharp UX-300. When I get a line error, the easiest way to clear it is to unplug the fax machine from the power outlet and let it stand for at least a minute. Then plug it back in to the power outlet. If this does not clear the problem, use a regular phone to check if the phone line between the fax machine and the wall is 'OK'.
