INTRODUCTION

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

RECEIVING. If your FAX/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 FAX/MFC continues to send the “chirps” for about 40 seconds, and the

LCD continues to display

RECEIVING. To cancel the receiving mode, press

Stop/Exit.

When your FAX/MFC answers in FAX/TEL mode, it listens for CNG tones and

then responds with receiving tones.

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.

ECM (Error Correction Mode)

The Error Correction Mode (ECM) is a way for the fax machine 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 FAX/MFC for this feature to work.

Note

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 for connecting a TAD to your FAX/MFC

in Chapter 2,

Assembly and Connections.
