● Try connecting a working phone and phone cord to the telephone wall jack
that you are using for the HP Fax 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 Fax, might be
in use. For example, you cannot use the HP Fax 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 Fax 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
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
● Make sure the HP Fax 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 Fax 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
● If the HP Fax shares the same phone line with a DSL service, the DSL
modem might not be properly grounded. If the DSL modem is not properly
grounded, it can create noise on the phone line. Phone lines with poor sound
