Checklist for solving fax problems

Use the following checklist to help identify the cause of any fax-related problems you encounter:

NOTE:

The steps vary according to the type of control panel.

●

Are you using the fax cable supplied with the fax accessory?

This fax accessory has been tested with the

supplied fax cable to meet RJ11 and functional

specifications.

Do not substitute another fax cable for the

supplied fax cable. The analog fax accessory requires an analog fax cable. It also requires an analog phone

connection.

●

Is the fax/phone line connector seated in the outlet on the fax accessory?

Make sure that the phone jack is

correctly seated in the outlet. Insert the connector into the outlet until it clicks or is

firmly

seated.

NOTE:

Verify that the phone jack is connected to the fax port rather than to the network port. The ports

are similar.

●

Is the phone wall jack working properly?

Verify that a dial tone exists by attaching a phone to the wall jack.

Can you hear a dial tone, and can you make or receive a phone call?

What type of phone line are you using?

●

Dedicated line:

A standard analog fax/phone line assigned to receive or send faxes.

NOTE:

The phone line should be for printer fax use only and not shared with other types of telephone

devices. Examples include alarm systems that use the phone line for

notifications

to a monitoring

company.

●

PBX system:

A business-environment phone system. Standard home phones and the fax accessory use an

analog phone signal. Some PBX systems are digital and might not be compatible with the fax accessory.

You might need an interfacing Analog Telephone Adapter (ATA) to connect the fax machine to digital PBX

systems.

●

Roll-over lines:

A phone system feature where a new call "rolls over" to the next available line when the

first

incoming line is busy. Try attaching the printer to the

first

incoming phone line. The fax accessory

answers the phone after it rings the number of times set in the rings-to-answer setting.
