6. Connect your answering machine to the other open phone port on the parallel
splitter.
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 the HP All-in-One.
7. (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.
8. If your modem software is set to receive faxes to your computer automatically,
turn off that setting.
NOTE: If you do not turn off the automatic fax reception setting in your
modem software, the HP All-in-One will not be able to receive faxes.
9. Turn on the Auto Answer setting.
10. Set your answering machine to answer after a low number of rings.
11. Change the Rings to Answer setting on the HP All-in-One to the maximum
number of rings supported by your device. (The maximum number of rings varies
by country/region.)
12. Run a fax test.
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.
