HP 7200 - Manual (Page 194)

Tip If your HP All-in-One came with a 2-wire phone cord adaptor, you
can use it with a 4-wire phone cord to extend the length. For information
on using the 2-wire phone cord adaptor, see the documentation that came
with it.
To extend your phone cord
1.
Using the phone cord supplied in the box with your HP All-in-One, connect
one end to the coupler, then connect the other end to the port labeled "1-
LINE" on the back of your HP All-in-One.
2. Connect another phone cord to the open port on the coupler and to the
telephone wall jack, as shown below.
1 Telephone wall jack
2 Coupler
3 Phone cord supplied in the box with the HP All-in-One
I am having problems faxing over the Internet
Solution
Check the following:
●
The FoIP service might not work properly when the HP All-in-One is sending
and receiving faxes at high speed (33600 bps). If you experience problems
sending and receiving faxes while using an Internet fax service, use a slower
fax speed. You can do this by changing the
Fax Speed setting from High
(the default) to Medium . For information on changing this setting, see Set
the fax speed .
● You can only send and receive faxes by connecting a phone cord to the port
labeled "1-LINE" on the HP All-in-One and not from the Ethernet port. This
means that your connection to the Internet must be done either through a
converter box (which supplies regular analog phone jacks for fax
connections) or your telephone company.
● Check with your telephone company to make sure their Internet phone
service supports faxing. If they do not support faxing, you will not be able to
send and receive faxes through the Internet.
