the printer and check for a dial tone. If you do not hear a dial tone, call your local telephone

Other equipment, which uses the same phone line as the printer, might be in use. For example,
you cannot use the printer for faxing if an extension phone is off the hook, or if you are using
a computer dial-up modem to send an email or access the Internet.
Check to see if another process has caused an error. 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 printer cannot send or receive a fax until the error condition is resolved.

cause faxing problems. Check the sound quality of the phone line by plugging a phone into the
telephone wall jack and listening for static or other noise. If you hear noise, turn Error Correction
Mode (ECM) off and try faxing again. For information about changing ECM, see Send a fax in
Error Correction Mode on page 66. If the problem persists, contact your telephone company.

remove power for at least 15 minutes. Turn the DSL modem back on and listen to the dial tone
NOTE: You might notice static on the phone line again in the future. If the printer stops sending
and receiving faxes, repeat this process.
If the phone line is still noisy, contact your telephone company. For information on turning your
DSL modem off, contact your DSL provider for support.
If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord
