ECM (Error Correction Mode)

The Error Correction Mode (ECM) is a way for the MFC to check a
fax transmission while it is in progress. ECM transmissions are only
possible between machines that both have this feature. If they do,
you may send and receive fax messages that are continuously being
checked by the machine.
Your MFC must have enough memory for this feature to work.

Connecting the MFC

Connecting an External Telephone

Although your MFC does not have a handset, you can connect a separate
telephone (or telephone answering device) directly to your MFC.
Connect the modular plug on the telephone's line cord to the jack
labeled EXT. on the left side of the MFC.
Whenever this phone (or TAD) is in use, the LCD shows TELEPHONE.
Connecting an External Telephone Answering
Device (TAD)

Sequence

You may choose to connect an answering system. However, when you
have an external TAD on the same telephone line as the MFC, the
TAD answers all calls and the MFC "listens" for fax calling (CNG) tones.
If it hears them, the MFC takes over the call and receives the fax. If it
doesn't hear CNG tones, the MFC lets the TAD continue playing your
outgoing message so your caller can leave you a voice message.
The TAD must answer within five rings (the recommended setting is
two rings). The MFC cannot hear CNG tones until the TAD has
answered the call, and with five rings there are only 8 to 10 seconds
of CNG tones left for the fax "handshake". Make sure you carefully
follow the instructions in this manual for recording your outgoing
message. We do not recommend using the toll saver feature on your
external answering machine if it exceeds five rings.
