• 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 product to an analog phone line or you will not be able
to 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
product to an analog phone line and try sending or receiving a fax.
NOTE: If you are unsure of the kind of phone line you have (analog or digital),
check with your service provider.
After you resolve any problems found, run the fax test again to make sure it passes
and the product is ready for faxing. If the Dial Tone Detection Test continues to fail,
contact your telephone company and have them check the phone line.
I am having problems faxing over the Internet using IP phone
Try the following solutions to resolve the issue. Solutions are listed in order, with the most
likely solution first. If the first solution does not solve the problem, continue trying the
remaining solutions until the issue is resolved.
• Solution 1: Change the fax speed
• Solution 2: Make sure the phone cord is connected to the correct port on the product
• Solution 3: Make sure the telephone company supports faxing over the Internet
Solution 1: Change the fax speed
Solution: 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 Fast (33600) (the default) to Medium (14400) or Slow (9600).
For more information, see:
“Set the fax speed” on page 18
Cause: The fax over Internet Protocol (FoIP) service might not have worked
properly when the product was sending and receiving faxes at high speed (33600
bps).
If this did not solve the issue, try the next solution.
Solution 2: Make sure the phone cord is connected to the correct port on the
product
Solution: You can only send and receive faxes by connecting a phone cord to the
port labeled 1-LINE on the product. 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.
Cause: The product was not set up properly for faxing.
