HP 7200 - Manual (Page 98)

Note If you do not connect your answering machine in this way, fax
tones from a sending fax machine might be recorded on your answering
machine, and you might not be able to receive faxes with your HP All-in-
One.
6. (Optional) If your answering machine does not have a built-in phone, for
convenience you might want to connect a phone to the back of your answering
machine at the "OUT" port.
7. If your computer modem software is set to receive faxes to your computer
automatically, turn off that setting.
Caution If you do not turn off the auto fax receive setting in your
computer modem software, your HP All-in-One will not be able to receive
faxes.
8. Set up the HP All-in-One to answer incoming calls automatically. Press the Auto
Answer button until the light is on.
9. Set your answering machine to answer after four or fewer rings.
10. Change the Rings to Answer setting on your HP All-in-One to six rings.
For information on changing this setting, see Set the number of rings before
answering .
11. Run a fax test. For information, see Test your fax setup .
When the phone rings, your answering machine will answer after the number of rings
you have set, and then play your recorded greeting. The HP All-in-One monitors the
call during this time, "listening" for fax tones. If incoming fax tones are detected, the
HP All-in-One will emit fax reception tones and receive the fax; if there are no fax
tones, the HP All-in-One stops monitoring the line and your answering machine can
record a voice message.
