Check and make sure that the line coming from the wall jack is plugged into the port marked with an "L". The other port is to connect a telephone set or answering machine.

Trying to receive a fax. Display says


You have to cancel the fax. If its saying that then the paper sent to you was a legal sixe 8.5x14 and needs that type paper to receive the fax. Some faxes have legal trays and A4 but most don't.

Printer is not working


It is possible that the FAX in the memory is causing the problem. Try unplugging the printer from the wall and leave it off for a minute or two to see if it will clear the memory

Cannot recieve or send faxes


Check out the Easy Setup Instructions available here. If you can neither send nor receive faxes, you may not have the phone line connected to the correct port, see page 34 of the guide. Also check what receive mode the machine is set for. Pages 42 and 43 explain the different options and how to change the receive mode.

Canon MP780 issue on Mac OS/X


I just noticed that I had the telephone cable connected to the "Telephone" port on the back of the Fax/Printer. When I switched it to the "Line" port, suddenly the clicking stopped and the Memory/In Use light went off. Now we will see if I can Fax something. Hope this works for you too!
