Shared phone line

If the fax is going to share the phone line with other

devices, such as a phone, answering machine,

computer/computer modem, or caller ID box, or if you

have voicemail service included with your line, you must

follow these instructions to determine how to set up your

fax.

1. Follow the steps for the “Dedicated phone line” on

page 10.

2. Plug additional devices into the 2-EXT port on the

back of the device.

3. Use the following tables to determine the rest of your

fax configuration.

Use the fax setup tables

Use the fax setup tables to assist you in setting up the fax function on your device. To use the tables, follow these

steps:

Determine how you will use the phone line that your fax machine will be using:

Once you determine how you want to use the phone line, follow these steps:

In the first row, determine what other devices will

share the phone line with the all-in-one (phone,

computer, answering machine).

In the next rows, determine if the phone line has any

special services (voicemail or distinctive ring), and, if the

phone line will be used with a computer, determine if

you have a dial-up or DSL modem.

The next row provides an example of what your fax

setup might look like in terms of how to connect various

devices to the all-in-one.

In the last row of the table are numbers that

correspond to the Configuration guideline table on

page 13. Use the Configuration guideline table to help

you set up your all-in-one so that it operates the most

effectively based on the way your all-in-one is set up.

NOTE: You must follow the numbers as they appear in

the last row of each fax setup table. Performing the steps

out of sequence may result in fax setup problems.

Configuration instructions

1

Set up the device to answer incoming calls automatically. Press the Auto Answer button until the light is

on.

2

(Optional) Change the Rings to Answer setting to one ring or two rings.
For information on changing this setting, see the onscreen user guide on the Starter CD.

3

Determine how you want the device to answer calls: automatically or manually.
• If you set up the device to answer calls automatically, it answers all incoming calls and receives

faxes. Your device will not be able to distinguish between fax and voice calls in this case; if you

suspect the call is a voice call, you will need to answer it before the device answers the call.
To answer fax calls automatically, press the Auto Answer button until the light is on.

• If you set up the device to answer faxes manually, you must be available to respond in person to

incoming fax calls or your device cannot receive faxes.
To answer fax calls manually, press the Auto Answer button until the light is off.

4

(Dial-up modem)

Since your PC modem shares the phone line with your device, you will not be able to use both your PC

modem and your device simultaneously. For example, you cannot use your device for faxing if you are

using your PC modem to send an e-mail or access the Internet.

5

(Dial-up modem)

If your PC modem software is set to receive faxes to your computer automatically, turn off that setting.
Caution: If you do not turn off the auto fax receive setting in your PC modem software, your device will

not be able to receive faxes.

6

When the phone rings, your device will answer automatically after the number of rings you set in the

Rings to Answer setting. Then it will begin emitting fax reception tones to the sending fax machine and

receive the fax.

7

(Answering machine)

Set your answering machine to answer after four or fewer rings.
Change the Rings to Answer setting on your device to six rings.
When the phone rings, your answering machine will answer after the number of rings you have set, and

then play your recorded greeting. The device monitors the call during this time, “listening” for fax tones.

If incoming fax tones are detected, the device will emit fax reception tones and receive the fax; if there

are no fax tones, the device stops monitoring the line and your answering machine can record a voice

message.

8

DSL lines only: You will need to purchase additional DSL filters for all devices (telephone, computer) that

share the DSL phone line.

(Distinctive ring

service)

Change the Answer Ring Pattern setting to the pattern that has been assigned to your fax number by the

telephone company, for example, double rings or triple rings.
For information on changing this setting, see the onscreen user guide on the Starter CD.
NOTE: Your device is factory-set to answer all ring patterns. If you do not set the correct ring pattern

assigned to your fax number by the telephone company, your device might answer both voice calls and

fax calls, or it might not answer at all.

There are two different ways to set up your device with your computer based on the number of phone

ports on your computer. You also need additional phone cords (at least three if your computer has only

one phone port and at least two if your computer has two phone ports).
Before you begin, check your computer to see if it has one or two phone ports:
Computer with one phone port
If your computer has only one phone port, you will need to purchase a parallel splitter (also called a

coupler). A parallel splitter has one RJ-11 port on the front and two RJ-11 ports on the back. Do not use

a two-line phone splitter, a serial splitter, or a parallel splitter which has two RJ-11 ports on the front and

a plug on the back. You can purchase a parallel splitter from an electronics store that carries phone

accessories.
1. Connect one end of the phone cord that came with the device to the wall jack and the other end to

the 1-LINE port on the device.

2. Connect one end of a second phone cord to the 2-EXT port on the device and the other end to the

front of the parallel splitter (the end with the single phone port).

3. Connect one end of a third phone cord to the back of the parallel splitter (the end with two phone

ports) and the other end to the computer.

4. Connect one end of a fourth phone cord to the last open port on the parallel splitter and the other

end to a telephone or answering machine. If you are connecting both a telephone and answering

machine, connect the fourth phone cord to the answering machine, and then use a fifth phone cord

to connect the answering machine to the telephone.
NOTE: If you do not connect your answering machine in this way, fax tones from a sending fax

machine might be recorded on your answering machine, and you might not be able to receive

faxes with your device.

Computer with two phone ports
If your computer has two phone ports, complete the following steps to connect the device to the

computer:
1. Connect one end of the phone cord that came with the device to the wall jack and the other end to

the 1-LINE port on the device.

2. Connect one end of a second phone cord to the 2-EXT port on the device and the other end to the

IN port on the computer.

3. Connect one end of a third phone cord to the OUT port on the computer and the other end to a

telephone or answering machine. If you are connecting both a telephone and answering machine,

connect the third phone cord to the answering machine, and then connect the answering machine

to the telephone.
NOTE: If you do not connect your answering machine in this way, fax tones from a sending fax

machine might be recorded on your answering machine, and you might not be able to receive

faxes with your device.
