be connected to the port labeled 1-LINE on the back of the HP All-in-One
and the other end to your telephone wall jack, as shown below.
1 Telephone wall jack
2 Use the phone cord supplied in the box with the HP All-in-One to connect to the
"1-LINE" port
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.
● 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, call your local telephone company for service.
● Other equipment, which uses the same phone line as the HP All-in-One,
might be in use. For example, you cannot use the HP All-in-One for faxing if
an extension phone is off the hook, or if you are using a computer dial-up
modem to send an e-mail or access the Internet.
● Check to see if another process has caused an error. Check the display or
your computer for an error message providing information about the problem
and how to solve it. If there is an error, the HP All-in-One will not send or
receive a fax until the error condition is resolved.
● The phone line connection might be noisy. Phone lines with poor sound
quality (noise) can cause faxing problems. Check the sound quality of the
phone line by plugging a phone into the telephone wall jack and listening for
static or other noise. If you hear noise, turn Error Correction Mode (ECM)
off and try faxing again. For information about changing ECM, see the
onscreen Help. If the problem persists, contact your telephone company.
● If you are using a digital subscriber line (DSL) service, make sure that you
have a DSL filter connected or you will not be able to fax successfully. For
more information, see Case B: Set up the HP All-in-One with DSL.
● Make sure the HP All-in-One is not connected to a telephone wall jack that is
set up for digital phones. 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.
● If you are using either a private branch exchange (PBX) or an integrated
services digital network (ISDN) converter/terminal adapter, make sure the
HP All-in-One is connected to the correct port and the terminal adapter is set
to the correct switch type for your country/region, if possible. For more
