electronics store that carries phone accessories. You also need another

phone cord, which can be a standard phone cord that you might already

have in your home or office.

• 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, call your local telephone company for service.

• 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.

• The phone line connection might be noisy. Phone lines with poor sound

quality (noise) can 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. If the problem persists, contact your

telephone company.

• If you are using a digital subscriber line (DSL) service, make sure that you

have a DSL filter connected or you cannot fax successfully. For more

information, see

Case B: Set up the printer with DSL.

• Make sure the printer is not connected to a telephone wall jack that is set up

for digital phones. 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.

• If you are using either a private branch exchange (PBX) or an integrated

services digital network (ISDN) converter/terminal adapter, make sure the

printer is connected to the correct port and the terminal adapter is set to the

correct switch type for your country/region, if possible. For more information,

see

Case C: Set up the printer with a PBX phone system or an ISDN line.
