Solve fax problems
If you still have problems using fax after successfully
completing the fax test, 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 test 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 test 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 test report and
fax log (and if available, the Caller ID report and
Junk Fax report), and then contact HP for further
help.
7. Note: If you have subscribed to a voice mail 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 voice mail 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 selecting Fax on the printer
display.
• 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 1-LINE port on
the back of the printer to the phone wall jack and
connect a phone cable from the 2-EXT port 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, press *
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 which 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.
