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 and functional specifications. Do not
substitute another phone cord; the analog-fax accessory requires an analog phone cord. It also
requires an analog phone connection.
●
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.
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 companies.
●
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.
