Checklist for solving fax problems

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

●

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; 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."

●

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 product 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 need to have access to a standard analog phone connection to be

able to send and receive faxes.

●

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 product 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.

NOTE: Roll-over lines can cause problems with receiving faxes. Using roll-over lines with this

product is not recommended.

Are you using a surge-protection device?

A surge-protection device can be used between the wall jack and the fax accessory to protect the fax

accessory against electrical power passed through the phone lines. These devices can cause some fax

communication problems by degrading the quality of the phone signal. If you are having problems

sending or receiving faxes and are using one of these devices, connect the product directly to the

phone jack on the wall to determine whether the problem is with the surge-protection device.
