Solve fax problems
If you still have problems using fax after successfully completing the fax test on page 1, follow the steps below:
Cannot send but can receive faxes
1. Perform a copy or scan to ensure that the printer is
working properly.
2. Check the physical fax connections.
3. Check if other fax devices can send to the same phone
number. The receiving fax device might have blocked
your phone number, or it might be having technical
problems.
4. If the problem persists, print the Fax Error Report and
Fax Log (and if available, the caller ID report and junk
fax report), and then contact HP for further help.
Cannot receive but can send faxes
1. Check the fax settings on the printer.
2. Check the physical fax connections.
3. Check if other devices connected to the same phone
line can receive faxes. The phone line might be faulty
or the sending fax device might be having problems
sending faxes. You might also want to check if you
have blocked the sender's phone number.
4. Check the problem with the sender. If the problem
persists, print the Fax Error Report and Fax Log (and if
available, the caller ID report and junk fax report), and
then contact HP for further help.
Cannot send and receive faxes
1. Perform a copy or scan to ensure that the printer is
working properly.
2. Check the physical fax connections.
3. Check the fax settings on the printer.
4. Check if other devices connected to this phone line can
send or receive faxes. There might be a problem with
the phone line.
5. Reset the printer by turning off the printer and, if
possible, the main switch of the power supply. Wait for
a few seconds before turning on the power again. Try
to send or receive a fax on the printer.
6. If the problem persists, print the Fax Error Report and
Fax Log (and if available, the caller ID report and junk
fax report), and then contact HP for further help.
If you have subscribed to a voicemail service on the
same phone line used for faxing, you will have to
receive faxes manually.
Check the printer fax settings
• The Auto Answer feature is turned on for the printer to
receive fax automatically.
• If you have subscribed to a voicemail service from
the phone company or service provider, ensure that
the Rings to Answer on the printer is set to be more
than that of the telephone answering machine. The
printer will monitor the line and decide if an incoming
call is a normal phone call or fax call. If it is a fax call,
the printer will start a fax connection automatically.
Otherwise, you might have to receive the fax manually
by touching Fax.
• If multiple phone numbers are assigned to the same
physical phone line and the line is shared by multiple
devices, ensure that the printer is set to the correct
distinctive ring setting for receiving faxes.
Check the physical fax connections
• Connect the phone cable from the port labeled 1-LINE
on the back of the printer to the phone wall jack and
connect a phone cable from the port labeled 2-EXT on
the back of the printer to an extension phone. From the
extension phone, call the phone number that failed to
receive the faxes.
If you were trying to fax to an external number,
be sure to include any required access code or
numbers prior to entering the number. You might
also need to add a pause in the number to prevent
the printer from dialing too fast; to add a pause,
touch * repeatedly until a dash (-) appears on the
display.
• If you cannot make any outgoing calls because no dial
tone is detected or the line is noisy, try using another
phone cable in place of the one connected to the 1-LINE
phone port, or move the printer to another location
that has a separate phone line (if possible) and see if
there are similar problems.
• If you are in a digital phone environment (such as FoIP,
fax over VoIP), reduce the fax speed and turn off the
Error Code Modulation (ECM) from the printer control
panel. If needed, contact your phone company to find
out if there are problems with the phone line or to learn
more about the capabilities of the phone network.
