Connecting an external
device to your MFC
Connecting an external
telephone
You can connect a separate telephone (or
telephone answering device) directly to your
MFC as shown in the diagram below.
Connect the telephone line cord to the jack
labeled EXT. in the left of the MFC.
When you are using an external phone, the
LCD shows
Telephone.
Connecting an external
telephone answering device
(TAD)
Sequence
You may choose to connect an external
answering device. 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 does not 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 four rings (the
recommended setting is two rings). The MFC
cannot hear CNG tones until the TAD has
answered the call, and with four 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 guide for
recording your outgoing message. We do not
recommend using the toll saver feature on
your external answering machine if it exceeds
five rings.
Note
■ If you do not receive all your faxes, reduce
the Ring Delay setting on your external
TAD.
■ If You Subscribe to your Telephone
Company’s Distinctive Ring Service:
You may connect an external TAD to a
separate wall jack only if you subscribe to
your telephone company’s Distinctive
Ring service, have registered the
distinctive ring pattern on your MFC, and
use that number as a fax number. The
recommended setting is at least four rings
on the external TAD when you have the
telephone company’s Distinctive Ring
Service. You cannot use the Toll Saver
setting.
■ If You Do Not Subscribe to Distinctive
Ring Service:
You must plug your TAD into the EXT.
jack of your MFC. If your TAD is plugged
into a wall jack, both your MFC and the
TAD will try to control the phone line.
