A line error occurs when your machine cannot
communicate correctly with another fax machine. The
error is usually due to a problem on the phone line.
Try faxing again. If unsuccessful, check the following:
• Check the connection. The cord from the TEL. LINE
socket to the wall socket should be no longer than two
meters.
• Make sure there are no modem devices sharing the
same telephone line.
• Check with the other party to make sure their fax
machine is functioning properly.
• Have your telephone line checked for line noise.
• Try connecting the machine to a different phone line.
• If the error persists, the machine may need service.
• Make sure that the telephone line is properly
connected to both the TEL. LINE socket and the wall
socket (see page 9).
• Make sure that the telephone line is good.
