2 Phone cord supplied in the box with your HP All-in-One
If the supplied phone cord is not long enough, you can extend it. For

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, contact your telephone company and have them check
the line.
● Other equipment, which uses the same phone line as the HP All-in-One,
might be in use. For example, you cannot use your HP All-in-One for faxing if
an extension phone is off the hook, or if you are using your computer modem
to send an e-mail or access the Internet.
● Check to see if another process has caused an error. Check the control
panel 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
HP Image Zone 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 your HP All-in-One with DSL .
● Make sure your 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
information, see
Case C: Set up your HP All-in-One with a PBX phone
system or an ISDN line .
● If your HP All-in-One shares the same phone line with a DSL service, the
DSL modem might not be properly grounded. If the DSL modem is not
