receive faxes automatically. Modems with the auto fax receive feature turned
on will receive all incoming faxes, which prevents the HP All-in-One from
receiving fax calls.
● If you have an answering machine on the same phone line with your HP All-
in-One, you might have one of the following problems:
–
Your answering machine might not be set up properly with your HP All-
in-One.
– Your outgoing message might be too long or too loud to allow the HP All-
in-One to detect fax tones, and the calling fax machine might disconnect.
– Your answering machine might hang up too quickly after the outgoing
message plays if it does not detect someone trying to record a message,
as when a fax is calling. This prevents the HP All-in-One from detecting
the fax tones. This problem is most common with digital answering
machines.
Try the following:
–
When you have an answering machine on the same phone line you use
for fax calls, try connecting the answering machine directly to the HP All-
in-One as described in
Fax setup .
– Make sure your HP All-in-One is set to receive faxes automatically. For
information on setting up your HP All-in-One to receive faxes
automatically, see
Set up the HP All-in-One to receive faxes .
– Make sure the Rings to Answer setting is correct. Set your answering
machine to answer in 4 rings and your HP All-in-One to answer in the
maximum number of rings supported by your device. (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 information on setting the number of rings to
answer, see
Set the number of rings before answering .
– Disconnect the answering machine and then try receiving a fax. If you
can receive a fax without the answering machine, the answering
machine might be causing the problem.
– Reconnect the answering machine and rerecord your outgoing
message. Make sure the message is as short as possible (no more than
10 seconds long), and that you speak softly and slowly when recording
it. At the end of your message, leave 3 - 4 seconds of silence with no
background noise. Try to receive a fax again.
Note Some digital answering machines might not retain the
recorded silence at the end of your outgoing message. Play back
your outgoing message to check.
● If your HP All-in-One shares the same phone line with other types of phone
equipment, such as an answering machine, a computer modem, or multi-port
switch box, the fax signal level might be reduced. This can cause problems
during fax reception.
To find out if other equipment is causing a problem, disconnect everything
except the HP All-in-One from the phone line, and then try to receive a fax. If
you can receive faxes successfully without the other equipment, one or more
pieces of the other equipment is causing problems; try adding them back one
