Cannot get dial tone to send a fax

? Other equipment, which uses the same phone line as the HP All-in-One,
might be causing the test to fail. To find out if other equipment is causing a
problem, disconnect everything from the phone line, and then run the test
again. If the Dial Tone Detection Test passes without the other equipment,
then one or more pieces of the equipment is causing problems; try adding
them back one at a time and rerunning the test each time, until you identify
which piece of equipment is causing the problem.
? Try connecting a working phone and phone cord to the telephone wall jack
that you are using for the HP All-in-One and check for a dial tone. If you do
not hear a dial tone, contact your telephone company and have them check
the line.
? Make sure you have correctly connected the HP All-in-One to the telephone
wall jack. Using the phone cord supplied in the box with the HP All-in-One,
connect one end to your telephone wall jack, then connect the other end to
the port labeled 1-LINE on the back of the HP All-in-One.

If the supplied phone cord is not long enough, you can extend it. For
information, see The phone cord that came with my HP All-in-One is not long
enough.
Check the connection between the telephone wall jack and the HP All-in-One
to make sure the phone cord is secure.
Make sure you use the phone cord that came with the HP All-in-One. If you
do not use the supplied phone cord to connect from the telephone wall jack
to the HP All-in-One, you might not be able to send or receive faxes. After
you plug in the phone cord that came with the HP All-in-One, run the fax test
again.
If you are using a phone splitter, this can cause faxing problems. (A splitter is
a two-cord connector that plugs into a telephone wall jack.) Try removing the
splitter and connecting the HP All-in-One directly to the telephone wall jack.

splitter and connecting the HP All-in-One directly to the telephone wall jack.
If your telephone system is not using a standard dial tone, such as some
PBX systems, this might cause the test to fail. This will not cause a problem
sending or receiving faxes. Try sending or receiving a test fax.
Check to make sure the country/region setting is set appropriately for your
country/region. If the country/region setting is not set or is set incorrectly, the
test might fail and you might have problems sending and receiving faxes.
Make sure you connect the HP All-in-One to an analog phone line or you will
not be able to send or receive faxes. To check if your phone line is digital,
connect a regular analog phone to the line and listen for a dial tone. If you do
not hear a normal sounding dial tone, it might be a phone line set up for
digital phones. Connect the HP All-in-One to an analog phone line and try
sending or receiving a fax.
Make sure you use the phone cord that came with the HP All-in-One. If you
do not use the supplied phone cord to connect from the telephone wall jack
to the HP All-in-One, you might not be able to send or receive faxes. After
you plug in the phone cord that came with the HP All-in-One, run the fax test
again.
After you resolve any problems found, run the fax test again to make sure it
passes and the HP All-in-One is ready for faxing. If the Dial Tone Detection test
continues to fail, contact your telephone company and have them check the
phone line.

This is often caused by the wrong country setting in Windows, as different countries use different dialtones.

Make sure your computer is set correctly in Regional and Language Options in Control Panel.

Go to menu option and choose the option fax and set the parameter like auto receive or manual set the ring auto answer mode after certain ring. If it is in auto receiving mode it will receive the fax after the ring which you set. Make sure the phone wire which you insert in fax machine getting proper dial tone and getting out going calling facility.
Have a nice day and do not forget to rate please...!

Remove the phone line from the back of the fax and connect a standard phone (not a business PABX or PAX system phone) to the line. Ensure dialtone is available. (Make sure in doing this that you are also testing the cable from the phone socket to the fax). If no dialtone, replace cable or fix line.

Check that the line is connected to the 'line' port on the fax, not the 'phone' port.

If still no dial tone, it may be modem fault (in the fax). Seek specialist attention.

Check for dial tone at the fax machine

Plug in a telephone on the cable from the wall.
Do you get a dial tone?
Yes,
Something is wrong with the fax machine.
No,
Call the phone company or a telephone repairman.

There are two outlets in the back where you plug in your phone line. I had the same problem when I
was plugged into the far left plug (as you are facing the front of the all in one). I switched to the other
outlet and it worked fine. But still once in a while it seems to loosen up and I have to push it back in
farther. Today I got a dialtone but could not send a fax. I got a dialtone but still wouldn't send. So I
checked the outlet and sure enough, it was just loose enough to prevent the machine from registering
the fax number, but connected enough to get a dialtone.....go figure. Good luck

connect a phone with 4521 in the back side jack of phoneout,
for outgoing fax
place original in the adf or glass for fax
Press hookdial and dial your sending fax number in 4521 after number dialing pull the phone handset to ear when you leason fax tone from the dialing number press start button to send fax.

for incoming fax (in not automoated)

Check the phone line with a regular phone and listen for a dial-tone.

• If you are using speed dial to dial the fax number, the HP Officejet
might be dialing too fast or too soon. To solve this problem, try one
of the following:
– Try manually dialing the fax number from the HP Officejet front
panel, or from an attached phone. For information, see send a
fax using monitor dialing on page 43 or send a fax manually
from a telephone on page 43.
– Re-create the speed dial setting and insert some pauses. For
information, see create individual speed-dial entries on
page 56.
• If your telephone line has a PBX system, make sure you are dialing
the number for an outside line before dialing the fax number.
• The receiving fax machine might be having problems. To check this,
try calling the fax number from a telephone and listen for fax tones.
If you cannot hear fax tones, the receiving fax might not be turned
on or connected, or a voice mail service could be interfering with
the recipient’s phone line.
