● 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.
The following actions might help solve these problems:
– 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 Fax setup.
– Make sure the Rings to Answer setting is set to a greater number of
rings than the answering machine. For more information, 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 record your outgoing message
again. Record a message that is approximately 10 seconds in duration.
Speak slowly and at a low volume when recording your message. Leave
at least 5 seconds of silence at the end of the voice message. There
should be no background noise when recording this silent time. 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
at a time and receiving a fax each time, until you identify which equipment is
causing the problem.
● If you have a special ring pattern for your fax phone number (using a
distinctive ring service through your telephone company), make sure that the
Answer Ring Pattern feature on your HP All-in-One is set to match. For
more information, see Change the answer ring pattern (distinctive ringing).
