Make sure you use the phone cord that came with the printer. If you do not use the supplied phone cord
to connect from the telephone wall jack to the printer, you might not be able to send or receive faxes.
After you plug in the phone cord that came with the printer, run the fax test again.
●
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.
The "Dial Tone Detection" test failed
●
Other equipment, which uses the same phone line as the printer, might be causing the test to fail. To find
out if other equipment is causing a problem, disconnect everything from the phone line, and then run
the test again. If the Dial Tone Detection Test passes without the other equipment, then one or more
pieces of the equipment is causing problems; try adding them back one at a time and rerunning the test
each time, until you identify which piece of equipment is causing the problem.
●
Try connecting a working phone and phone cord to the telephone wall jack that you are using for the
printer and check for a dial tone. If you do not hear a dial tone, contact your telephone company and
have them check the line.

Make sure you have correctly connected the printer to the telephone wall jack. Using the phone cord
supplied in the box with the printer, connect one end to your telephone wall jack, then connect the other
end to the port labeled 1-LINE on the back of the printer.

●
If your telephone system is not using a standard dial tone, such as some private branch exchange (PBX)
systems, this might cause the test to fail. This does not cause a problem sending or receiving faxes. Try
sending or receiving a test fax.
●
Check to make sure the country/region setting is set appropriately for your country/region. If the
country/region setting is not set or is set incorrectly, the test might fail and you might have problems
sending and receiving faxes.
●
Make sure you connect the printer to an analog phone line or you cannot send or receive faxes. 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. Connect the
printer to an analog phone line and try sending or receiving a fax.

check the phone line.
