Hi my name is lionel whenever i try sending a fax line error message comes up fax does not go what is the problem. thanks

No. Most of the time this "phone line error" can be caused by the telephone connection or issue on the phone line where the fax machine is connected.
Hope this will help.

It is not your fax line is the other party.did you try any other number?

Hi, you can check that your phone connection from your 7420 to line works. Listen for a dial tone in a phone connected to your mfc7420. If not, your tel comm module could be at fault.

hi!!

try to re-installe the driver of your printer

I have been sending and receiving faxes for over a year on my Lexmark X6100 printer. Now whenever I try to send a fax it will say it is sending the pages but then waits for a redial. After doing the same thing a second time it will print out "remote fax error"

I try sending a fax then the paper goes through it makes a loud beep and the message says theres been an error try again this happens all the time no matter who I fax. then it prints out error confirmation stating Mode G3 send error

What happens if you dial the remote fax number as a voice call on another phone? Does that number pick up? Does it give you the modem handshake noise? If not, the remote side has a problem.
Can you fax other numbers? What happens when you dial your own fax line from another phone? If your fax does not pick up and talk to you, your fax may have a problem.

Code 43 is a line error according to Panasonic.

I had this issue trying to send to a client yet I could send faxes to other #'s. So in my case it was a dead fax on the other end of the line.

Try to send the fax at a different time when telephone line conditions have improved.
Or try to disable the ECM on yuor printer, to do that to these steps:

Press SETUP
Press DOWN until you ADVANCE FAX SETUP displays
Press OK
Press DOWN until ERROR CORRECTION MODE displays
Press OK
Press RIGHT ARROW to turn it off
Press OK

Then try to send new fax. If this does not resolved your issue pls try to go to your phone provider. Thanks
