							6.Connect your answering machine to the other open phone port on the parallel
splitter.
NOTE:If you do not connect your answering machine in this way, fax tones
from a sending fax machine might be recorded on your answering machine,
and you might not be able to receive faxes with the HP All-in-One.
7.(Optional) If your answering machine does not have a built-in phone, for
convenience you might want to connect a phone to the back of your answering
machine at the OUT port.
8.If your modem software is set to receive faxes to your computer automatically,
turn off that setting.
NOTE:If you do not turn off the automatic fax reception setting in your
modem software, the HP All-in-One will not be able to receive faxes.
9.Turn on the Auto Answer setting.

11.Change the Rings to Answer setting on the HP All-in-One to the maximum
number of rings supported by your device. (The maximum number of rings varies
by country/region.)
12.Run a fax test.
When the phone rings, your answering machine will answer after the number of rings
you have set, and then play your recorded greeting. The HP All-in-One monitors the
call during this time, listening for fax tones. If incoming fax tones are detected, the
HP All-in-One will emit fax reception tones and receive the fax; if there are no fax
tones, the HP All-in-One stops monitoring the line and your answering machine can
record a voice message.
Cause:I am setting up the HP All-in-One on a shared voice/fax line with a computer
dial-up modem and voice mail service, and the computer has only one phone port.

2Use the phone cord supplied in the box with the HP All-in-One
This special 2-wire phone cord is different from the more common 4-wire phone cords
you might already have in your office. Check the end of the cord and compare it to
the two types of cords shown below.
If you used a 4-wire phone cord, disconnect it, find the supplied 2-wire phone cord,
and then connect the 2-wire phone cord to the port labeled 1-LINE on the back of the
HP All-in-One.
If the HP All-in-One came with a 2-wire phone cord adaptor, you can use it with a 4-
wire phone cord, in case the supplied 2-wire phone cord is too short. Attach the 2-
wire phone cord adaptor to the port labeled 1-LINE on the back of the HP All-in-One.
Attach your 4-wire phone cord to the open port on the adaptor and to the telephone
wall jack. For more information on using the 2-wire phone cord adaptor, see the
documentation that came with it.
For more information on setting up the HP All-in-One, see the printed documentation
that came with the HP All-in-One.
Cause:You are using a phone line splitter between the 1-LINE port on the HP All-
in-One and the wall.
Solution:A phone line splitter can affect the sound quality of your phone line and
cause static. (A splitter is a two-cord connector that plugs into a telephone wall jack.)

							Solution:
What to do
•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.
•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 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. For more information, see 
Set up the
HP All-in-One for faxing.
•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 except the HP All-in-One from the phone line, and then run
the test again.
• If the Fax Line Condition 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.
• If the Fax Line Condition Test fails without the other equipment, connect the
HP All-in-One to a working phone line and continue reviewing the
troubleshooting information in this section.
•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.
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 Fax Line Condition Test continues
to fail and you experience problems faxing, contact your telephone company and
have them check the phone line.
