handset of the external telephone and dialling the number using the external
telephone. Wait to hear the fax receiving tones before sending the fax.
If there is no dial tone, connect a known working telephone and telephone line
cord to the socket. Then lift the external telephone’s handset and listen for a dial
tone. If there is still no dial tone, ask your telephone company to check the line
and/or wall socket.

Check for a dial tone. If possible, call your machine to hear it answer. If there is

answering machine, an alarm system or other custom feature on a single
telephone line with your machine, it may create a problem sending or receiving
faxes.
For Example: If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a
fax, the signal can temporarily interrupt or disrupt the faxes. Brother’s ECM (Error
Correction Mode) feature should help overcome this problem. This condition is
