If you cannot send or receive a fax, check the following:
1
Connect one end of the telephone line cord to the area labelled "LINE", and then connect
the other end of the telephone line cord directly to a telephone wall jack.
If you can send and receive faxes when the telephone line is directly connected to the fax,
the problem may be unrelated to the machine. Please contact your telephone service
provider for connection issues.
2
Check the receive mode.
See Related Information:

3
Try changing the compatibility settings.
You may be able to send and receive faxes by lowering the connection speed.
