HP Officejet Pro 8600 - Manual (Page 132)

• If you have a computer dial-up modem on the same phone line with the
printer, check to make sure that the software that came with your modem is
not set to receive faxes automatically. Modems that are set up to receive
faxes automatically take over the phone line to receive all incoming faxes,
which prevents the printer from receiving fax calls.
• If you have an answering machine on the same phone line with the printer,
you might have one of the following problems:
◦
Your answering machine might not be set up correctly with the printer.
◦ Your outgoing message might be too long or too loud to allow the
printer to detect fax tones, and the sending fax machine might
disconnect.
◦ Your answering machine might not have enough quiet time after your
outgoing message to allow the printer to detect 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
printer as described in Case I: Shared voice/fax line with answering
machine.
◦ Make sure the printer is set to receive faxes automatically. For
information on setting up the printer to receive faxes automatically,
see Receive a fax.
◦ 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
faxing is successful 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.
