About Fax Machines
If you’re a first-time fax machine user, fax operation might seem a little
mysterious. Soon, you’ll recognize the unusual fax tones on your phone line,
and be able to send and receive faxes easily.

Fax Tones and Handshake
When someone is sending a fax, the MFC sends fax calling tones, (CNG

, and they continue for about 40 seconds after dialing.
During that time, the sending machine must begin the “handshake” with the
receiving machine. Each time you use automatic procedures to send a fax, you
are sending CNG tones over the phone line. You’ll soon learn to listen for these
soft beeps each time you answer a phone on your MFC line, so you can know if
you are receiving a fax message.

The receiving fax responds with fax receiving tones—loud, chirping sounds. A
receiving fax chirps for about 40 seconds over the phone line, and the LCD
shows RECEIVE. If your MFC is set to the FAX mode, it will answer every call
automatically with fax receiving tones. Even if the other party hangs up, your
MFC continues to send the “chirps” for about 40 seconds, and the LCD
continues to shows RECEIVE.

MFC continues to send the “chirps” for about 40 seconds, and the LCD

The fax “handshake” is the time in which the sending machine’s CNG tones and
the receiving machines “chirps” overlap. This must be for at least 2 to 4 seconds,
so the fax machines can understand how each is sending and receiving the fax.
The handshake cannot begin until the call is answered, and the CNG tones only
last for about 40 seconds after the number is dialed. Therefore, it’s important for
the receiving machine to answer the call in as few rings as possible.

ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for the MFC to check the integrity
of a fax transmission while it is in progress. ECM transmissions are possible
only between machines that both have the ECM feature. If they do, you may
send and receive fax messages that are continuously checked for their integrity.

Sufficient memory must be available in your MFC for this feature to work.
Note
When you have an external telephone answering device (TAD) on your MFC
line, your TAD will determine the number of rings before the call is answered.
Pay special attention to the directions in the Installation chapter for connecting
a TAD to your MFC.
