The receiving fax responds with fax receiving tones—loud, chirping sounds. A 
receiving fax chirps for about 60 seconds over the phone line, and the LCD 
shows 

. 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 60 seconds, and the LCD 
continues to show 

. To cancel the receiving mode, press 

Stop/Exit.

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 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 60 seconds after the number is dialed. Therefore, it’s important for the 
receiving machine to answer the call in as few rings as possible.

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.

When you have an external telephone answering device (TAD) on your fax 
line, your  TAD will determine the number of rings before the call is answered. 
Pay special attention to the directions chapter for connecting a TAD to your 
MFC in Chapter 2, Assembly and Connections.
