Is your fax set up correctly?

Use the following checklist to help identify the cause of any fax related problems you are encountering:

Are you using the phone cord supplied with the fax accessory? This fax accessory has been
tested with the supplied phone cord to meet RJ11 specifications. Do not substitute another phone
cord; the analog-fax accessory requires an analog phone cord. It also requires an analog phone

Is the fax/phone line connector seated in the socket on the fax accessory? Make sure that
the phone jack is well seated in the socket. The connector should be inserted into the socket 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 a phone call?

What type of phone line are you using?

Dedicated line: A standard fax/phone number assigned to receive or send faxes.


The phone line should be for mfp 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

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 line 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 fax accessory to the first incoming phone
line. The fax accessory will answer the phone after it rings the number of times set in the rings-to-
answer setting.


Roll-over lines can cause problems with the fax accessory's ability to receive 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 fax accessory directly to the
phone jack on the wall to determine whether the problem is with the surge-protection device.

Are you using a phone company voice-messaging service or an answering


If the rings-to-answer setting for the messaging service is lower than the rings-to-answer setting for the
fax accessory, the messaging service answers the call, and the fax accessory is not able to receive
faxes. If the rings-to-answer setting for the fax accessory is lower than that of the messaging service,
the fax accessory answers all calls, and no calls are routed to the messaging service.
