I cannot receive
faxes, but I can send
faxes
(continued)
• If you have a PC modem on the same phone line with your
HP PSC, check to make sure that the modem’s software is not set to
receive faxes automatically. Modems with this auto fax receive
feature turned on will take over the phone line to receive all
incoming faxes, which will prevent the HP PSC from receiving fax
calls.
• If you have an answering machine on the same phone line with
your HP PSC, you might have one of the following problems:
– Your outgoing message might be too long or too loud to allow
the HP PSC to detect fax tones, which could cause the calling
fax machine to disconnect.
– Your answering machine might not have enough quiet time
after your outgoing message to allow the HP PSC to detect fax
tones. This problem is more common with digital answering
machines.
The following actions might help solve these problems:
a. Disconnect the answering machine and then try receiving a
fax. If faxing is successful without it, the answering machine
might be causing the problem.
b. Reconnect the answering machine and re-record 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. Try again to receive a fax.
• 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 PSC is set to
match. For example, if the phone company has assigned your fax
number a double ring pattern, make sure Double Rings is selected
as the Answer Ring Pattern setting. For information on changing
this setting, see change the answer ring pattern (distinctive ringing)
on page 68.
Note that some ring patterns cannot be recognized by the HP PSC,
such as those with alternating short and long ringing patterns. If
you are having problems with a ring pattern of this type, ask your
phone company to assign a non-alternating ring pattern.
• If you are not using a distinctive ring service, check to make sure
that the Answer Ring Pattern feature on your HP PSC is set to All
Rings. For information, see change the answer ring pattern
(distinctive ringing) on page 68.
