Solve setup problems

The printer is having problems sending and receiving faxes

• Make sure you use the phone cord or adapter

that came with the printer. (If you do not use this

phone cord or adapter, the display might always

show Phone Off Hook.)

• Make sure extension phones (phones on the

same phone line, but not connected to the

printer) or other equipment is not in use or off the

hook. 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 email or access the Internet.

• If you are using a phone splitter, the splitter

could cause faxing problems. Try connecting the

printer directly to the telephone wall jack.

• Make sure that one end of the phone cord is

connected to the telephone wall jack, while the

other end is connected to the port labeled

“1-LINE” on the back of the printer.

• Try connecting a working phone directly to the

telephone wall jack and check for a dial tone. If

you do not hear a dial tone, contact your

telephone company to check the line.

• 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 it does not sound like a normal-

sounding dial tone, it might be a phone line set

The printer can send faxes but cannot receive faxes

• If you are not using a distinctive ring service,

check to make sure that the Distinctive Ring

feature on the printer is set to All Rings.

• If Auto Answer is set to Off, or if you subscribe to

a voicemail service on the same phone line that

you will use for faxing, you can only receive

faxes manually.

• If you have a computer dial-up modem on the

same phone line with the printer, check to make

sure that the software that came with your

modem is not set to receive faxes automatically.

• If you have an answering machine on the same

phone line with the printer:

-Check that the answering machine is working

properly.

-Make sure the printer is set to receive faxes

automatically.

up for digital phones. Connect the printer to an

analog phone line and try sending or receiving

a fax.

• Check the sound quality of the phone line by

plugging a phone into the telephone wall jack

and listening for static or other noise. Phone

lines with poor sound quality (noise) can cause

faxing problems. If you hear noise, turn Error

Correction Mode (ECM) off and try faxing

again.

• If you are using a DSL/ADSL service, make sure

that you have a DSL/ADSL filter connected.

Without the filter, you cannot fax successfully.

• If you are using either a PBX or an 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 you are using a Fax over IP service, try to use a

slower connection speed. If this does not work,

contact your Fax over IP service’s support

department.

-Make sure the Rings to Answer setting is set to

a greater number of rings than the answering

machine.

-Disconnect the answering machine and then

try receiving a fax.

-Record a message that is approximately 10

seconds in duration. Speak slowly and at a low

volume when recording your message. Leave

at least 5 seconds of silence at the end of the

voice message.

• Other equipment using the same phone line

might be causing the fax test to fail. You can

disconnect all the other devices and run the test

again. If the Dial Tone Detection Test passes,

then one or more of the other 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.
