Troubleshooting fax
Use the following checklist to help identify the cause of any fax-related problems that you encounter.
•
Are you using the phone cord that came with the MFP?
The fax functionality has been tested with the supplied phone cord to meet RJ11 specifications. Do not substitute
another phone cord. The analog fax 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?
Make sure that the phone jack is well seated in the socket. The connector should be inserted all the way into the
socket, until it is secure.
•
Is the phone jack on the wall working?
Verify that a dial tone exists by attaching a phone to the phone jack on the wall. 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.
•
PBX system: A business-environment phone system. Standard home phones and the fax use an analog phone
signal. Some PBX systems are digital and might not be compatible with the fax. You need to have access to a
standard analog phone line to be able to send and receive faxes.
