Connecting unit for sending faxes

? 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.

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.
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.

1. Make sure that you have plugged the phone cord directly and securely into the wall jack and into the back port of the fax product. The fax port on your product is marked "Line," "To Wall Jack," or with a wall jack symbol.
2. Make sure the Line Interface Unit (box that the phone cord plugs into) is fully seated into the back of the fax product.
3. Remove any other devices from the line such as splitters, credit card machines, or telephone answering machines.
4. Try sending and receiving faxes on a different fax line.
5. Try using a different telephone cord.
6. Have the phone company test your line for static or noise problems.
7. Turn Error Correction Mode (ECM) off, if you encounter the same error repeatedly.

A regular old (POTS) phone line will send/receive faxes just fine. If you want to connect it to your computer, you'll need TWO phone cords: one into the wall, and one into the computer, with both connecting into the fax machine itself. Those ports should be marked on the fax.

If you want to use the FAX - use the dedicated line to the FAX Machine..

CHECK WITH DIFFERENT CABLE
Try using a different telephone cord.

Are you plugging the phone line into the line jack or the phone jack on the fax machine, it should plug in to line. Also try and unplug/replug the units power cord as well as trying a different phone jack location.

1)Disconnect the power cord from the rear of the HP Fax machine.
2)Verify that the phone cable is fully inserted into the fax machine. If your model has a removable Line Interface Unit (LIU) where the phone line plugs into, verify that it is securely snapped in place.
3)If the HP Fax model belongs to the HP Officejet R80 Series , verify that the cable which goes from the Automatic Document Feeder assembly to the rear of the HP All-in-One base is connected.
4)Reconnect the power cord.After the fax reinitializes and it is ready, try to send and receive faxes again.

hi there,

May i know what is your purpose connecting those unit?

If you want your computer can dial up internet connection, just plug your phone line to computer modem port and other side plug to the phone port at your fax machine.

If you want your computer can send fax, same with above tips. but you must install fax program at your computer, so you can directly send fax through your computer.
