When you have an answering machine on the same phone line you use for fax calls, you must connect the answering machine directly to the HP All-in-One using the port labeled 2-EXT, as shown below.

1Telephone wall jack

2Connect to the IN port on the answering machine

3Connect to the OUT port on the answering machine

4Telephone (optional)

5Answering machine

6Use the phone cord supplied in the box with the HP All-in-One

Make sure the HP All-in-One is set to receive faxes automatically and that the Rings to Answer setting is correct. The number of rings to answer for the HP All-in-One should be greater than the number of rings to answer for the answering machine. If the answering machine and the HP All-in-One are set to the same number of rings to answer, both devices will answer the call and fax tones will be recorded on the answering machine.

Set your answering machine to a low number of rings and the HP All-in-One to answer in the maximum number of rings supported. (The maximum number of rings varies by country/region.) In this setup, the answering machine will answer the call and the HP All-in-One will monitor the line. If the HP All-in-One detects fax tones, the HP All- in-One will receive the fax. If the call is a voice call, the answering machine will record the incoming message.

For more information on setting up the HP All-in-One when you have an answering machine, see the printed documentation that came with the HP All-in-One.
