Cause: Auto Answer is turned off, which means that the HP All-in-One will not
answer incoming calls. You must be available to respond in person to incoming fax
calls, or the HP All-in-One will not answer the incoming fax call.
Solution: Depending on your office setup, you might be able to set the HP All-in-
One to answer incoming calls automatically. To find out what the recommended
answer mode is for your office setup, see
Choose the recommended answer mode
for your setup.
If you must have Auto Answer off, you will need to press Start Fax Black or Start
Fax Color to receive a fax.
TIP: If you are not close enough to the HP All-in-One to reach the control panel,
wait several seconds, and then press 1 2 3 on your phone. If the HP All-in-One
does not begin receiving the fax, wait several more seconds and press 1 2 3 again.
After the HP All-in-One begins to receive the fax, you can hang up the phone.
Cause: You subscribe to a voice mail service at the same phone number you use
for fax calls.
Solution: Set the HP All-in-One to answer faxes manually. You cannot receive
faxes automatically if you have a voice mail service at the same phone number you
use for fax calls. You must receive faxes manually; this means you must be available
to respond in person to incoming fax calls.
For more information on how to set up the HP All-in-One when you have a voice mail
service, see
Set up the HP All-in-One for faxing.
Cause: You have a computer dial-up modem on the same phone line as the HP All-
in-One.
Solution: If you have a computer dial-up modem on the same phone line as the
HP All-in-One, 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 HP All-in-One from receiving fax calls.
Cause: If you have an answering machine on the same phone line with the HP All-
in-One, you might have one of the following problems:
• Your outgoing message might be too long or too loud to allow the HP All-in-One
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 HP All-in-One to detect fax tones. This problem is most
common with digital answering machines.
