The message "Poor Line Condition" or "NG" appears on the Transmission Verification Report when I try to send a fax.

  1. Do you have to be connected to the Internet to make a phone call?



  2. Press the Hook key.

    • If there is a dial tone, go to Step 4.

    • If there is no dial tone, verify the telephone line is connected directly to the jack labeled LINE on the Brother machine.

      –If the machine still does not have a dial tone, go to Step 3.

      –If there is a dial tone, go to Step 4.


  3. Remove the telephone line cord from the wall jack and connect a known-working extension phone with a known-working telephone line cord to the same wall jack. Lift the handset of the telephone.

    • If there is no dial tone, the issue is related to the telephone line or wall jack. You should contact your telephone provider for assistance.

    • If there is a dial tone, disconnect the telephone line cord from the telephone and connect it to the jack labeled LINE on the Brother machine. Press the Hook key on the Brother machine and listen for a dial tone.

      –If there is a dial tone, go to Step 4.

    • If you still do not hear a dial tone, please contact Brother Customer Service from "Contact Us."


  4. Verify the quality of the dial tone.

    • If the dial tone quality is poor, contact your telephone service provider for further assistance.

    • If the dial tone is clear, go to Step 5.


  5. Do you have any splitters, commshare devices, credit card machines, or power strips connected to your machine or the telephone wall jack?

    • If no, go to Step 6.

    • If yes, these must be removed to continue troubleshooting. This is for testing purposes.

      –Removing such devices helps to determine if the problem is related to the Brother machine or another device on the line. Once the issue is resolved, you can attempt to reconnect the device and test on your own. Remove the device and go to Step 6.


  6. Send a test fax.

    Do not press the Hook key before dialing.


    • If the fax is received, the issue is resolved.

    • If the problem continues, go to Step 7.


  7. Connect the Brother machine to a different, known-working telephone line and attempt to send another test fax.

    Testing the Brother machine on a different, known-working telephone line will help determine if the problem is related to the Brother machine or telephone line.
