FAQs & Troubleshooting

Set up an answering machine (TAD) to work on the same line as the fax.

When you have an external telephone answering device (TAD) on the same telephone line as the fax machine, the TAD answers all calls and the fax machine "listens" for fax calling (CNG) tones. If it hears them, the fax machine takes over the call and receives the fax. If it doesn't hear CNG tones, the fax machine 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 fax machine 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 manual for recording your outgoing message. We do not recommend using the toll saver feature on your external answering machine if it exceeds four rings.


  1. Plug the telephone line cord from the wall jack into the back side of the fax machine, in the jack labeled LINE.
  2. Plug the telephone line cord from your external TAD into the back side of the fax machine, in the jack labeled EXT. (Make sure this cord is connected to the TAD at the TAD's telephone line jack, and not its telephone set jack.)
  3. Set your external TAD to four rings or less.
  4. Record the outgoing message on your external TAD.
  5. Set the TAD to answer calls.
  6. Set the Receive Mode to TAD:ANSWER MACH..

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 the fax machine, use that number as a fax number and set your machine's Receive mode to MANUAL. The Ring Delay setting on the TAD must be 4 rings or more when you have the telephone company's Distinctive Ring Service.


If You Do Not Subscribe to Distinctive Ring Service:

You must plug your TAD into the EXT. jack of the fax machine. If your TAD is plugged into a wall jack, both your fax machine and the TAD will try to control the phone line.


Do not connect a TAD elsewhere on the same phone line (unless you have the Distinctive Ring service).
