aio printer/fax no dial tone

happsNovember 9, 2011

I have a Canon MP780 all in one (printer/scanner/fax/copy) connected to an iMac via a USB cable. One telephone line cable goes from the wall to the MP780, and the other from the MP780 to the telephone. Sometimes, when I pick up the phone to make a call, I get no dial tone and the MP780 makes a clicking sound. I have tried using different telephones and it didn't solve the problem. Do you all think the problem is with the telephone line or the MP780?

Have you checked 'System preferences' to see if the fax modem is listed and the drivers show as installed correctly?

Yes I have, and the computer recognizes the unit.
