Question about Canon FAXPHONE L80 Laser

1 Answer

Fax machine does not always send a fax

I have a cannon L80 fax phone machine and sometimes it does not send a fax. We use this machine to fax appox 50 faxes per day and on average 5 or 6 do not make it to the people that is intended. I don't believe that it is our phone line or the people that we are faxing to because sometimes they get on and an hour later they don't. The report on the fax machine says it went ok but they never got it.

Re: fax machine does not always send a fax

I hear of this problem everywhere, Sometimes the conditions are not perfect with the phone lines. I little drop in voltage or interference can cause a loss of transmission. I use a VOIP line and get a few faxes lost during everyday use. No 100% solution.

Cannot receive faxes

Make sure that the telephone line from the wall is plugged into "LINE" and not "PHONE" on the fax machine. You might also call the fax number from a different phone to see if you can hear the fax tones.

When sending a fax on the faxphone L80 it pulls in duplicate page

There is a little rubber pad where original feed in. Look at it on edge and you'll see it has concave wear. Carefully remove black plastic hold down and flip rubber pad over. You'll have to make a new hole so it will lay flat.

To send a fax you do not need to enter anything into your fax. You have to make sure that you connect the telephone line to it's desgnated connector. You dial a number to send as if you are calling form a normal phone. If you ever get a ringing tone press start. You can enter any data trough the data registration after you make sure your fax is functioning properly.
