Checklist for solving fax problems
Use the following checklist to help identify the cause of any fax-related problems you encounter:
●
What type of phone line are you using?
●
Are you using a surge-protection device?
●
Are you using a phone company voice-messaging service or an answering machine?
●
Does your phone line have a call-waiting feature?
●
Check fax accessory status
● Are you using the fax cable supplied with the fax accessory? This fax accessory has been tested with the
supplied fax cable to meet RJ11 and functional specications. Do not substitute another fax cable; the
analog-fax accessory requires an analog-fax cable. It also requires an analog phone connection.
● Is the fax/phone line connector seated in the outlet on the fax accessory? Make sure that the phone jack is
correctly seated in the outlet. Insert the connector into the outlet until it "clicks."
NOTE: Verify that the phone jack is connected to the fax port rather than to the network port. The ports
are similar.
● 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 or receive a phone call?
What type of phone line are you using?
● Dedicated line: A standard analog fax/phone line assigned to receive or send faxes.
NOTE: The phone line should be for printer fax use only and not shared with other types of telephone
devices. Examples include alarm systems that use the phone line for notications to a monitoring
company.
● 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 might need an interfacing Analog Telephone Adapter (ATA) to connect the fax machine to digital PBX
systems.
● Roll-over lines: A phone system feature where a new call "rolls over" to the next available line when the rst
incoming line is busy. Try attaching the printer to the rst incoming phone line. The fax accessory answers
the phone after it rings the number of times set in the rings-to-answer setting.
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 printer 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 machine?
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 cannot receive faxes. If the rings-to-
