● If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that
plugs into a telephone wall jack.) Try removing the splitter and connecting the printer directly to the
telephone wall jack.
After you resolve any problems found, run the fax test again to make sure it passes and the printer is ready
for faxing. If the Fax Line Condition test continues to fail and you experience problems faxing, contact your
telephone company and have them check the phone line.

What kind of fax problem are you having?
The display always shows Phone O Hook
● HP recommends using a 2-wire phone cord.
● Other equipment that uses the same phone line as the printer might be in use. Make sure extension
phones (phones on the same phone line, but not connected to the printer) or other equipment are not in
use or o the hook. For example, you cannot use the printer for faxing if an extension phone is o the
hook, or if you are using a computer dial-up modem to send email or access the Internet.
The printer is having problems sending and receiving faxes
● Make sure the printer is turned on. Look at the display on the printer. If the display is blank and (the
Power button) light is not lit, the printer is turned o. Make sure the power cord is rmly connected to
the printer and plugged into a power outlet. Press (the Power button) to turn on the printer.
After turning on the printer, HP recommends you wait ve minutes before sending or receiving a fax. The
printer cannot send or receive faxes while it is initializing after being turned on.
● If HP Digital Fax has been enabled, you might not be able to send or receive faxes if the fax memory is
full (limited by printer memory).
