The HP Fax is having problems
sending and receiving faxes
Make sure the HP Fax is plugged in. Look at the display
on the HP Fax. If the display is blank the HP Fax is
unplugged. Make sure the power cord is firmly connected
to the HP Fax and plugged into a power outlet.
After plugging in the power cord, HP recommends you
wait five minutes before sending or receiving a fax. The
HP Fax cannot send or receive faxes while it is initializing
after being plugged in.

Check to see if another process has caused an error.
Check the display 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 Error Correction Mode (ECM) off and try faxing
again. For information about changing ECM, see
Send a fax in Error Correction Mode. 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.
•
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.

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 quality (noise) can
cause faxing problems. You can 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 your DSL modem and
completely remove power for at least 15 minutes.
Turn the DSL modem back on and listen to the dial
tone again.
NOTE: You might notice static on the phone line
again in the future. If the HP Fax stops sending and
receiving faxes, repeat this process.
If the phone line is still noisy, contact your telephone
company. For information on turning your DSL
modem off, contact your DSL provider for support.
