If you are still having problems faxing, set the Fax Speed to a slower rate such as
Medium (14400) or Slow (9600).

Cause: Other equipment that uses the same phone line as the HP All-in-One might
be in use.
Solution: Make sure extension phones (phones on the same phone line, but not
connected to the HP All-in-One) or other equipment are not in use or off the hook.
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 e-mail or access the
Internet.
Cause: The HP All-in-One shares the same phone line with a DSL service and a
DSL filter is not connected.
Solution: If you use a DSL service, make sure that you have a DSL filter connected
or you will not be able to fax successfully. The DSL service sends out a digital signal
on the phone line that can interfere with the HP All-in-One, preventing the HP All-in-
One from sending and receiving faxes. The DSL filter removes the digital signal and
allows the HP All-in-One to communicate properly with the phone line. To check if
you already have a filter installed, listen to your phone line or dial tone. If you hear
noise or static on the line, you probably do not have a DSL filter installed, or it is
installed incorrectly. Obtain a DSL filter from your DSL provider. If you already have
a DSL filter, make sure it is connected correctly.
Cause: Another process has caused an error in the HP All-in-One.
Solution: 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.
You can also check the status of the HP All-in-One by clicking Status in the
HP Solution Center.
For more information, see:
Cause: You are using either a PBX or an ISDN converter/terminal adapter.
