Problem with fax, unable to send or receive fax.  Fax test report says "fail" on the dial tone detected telephone line.  However, dial tone is detected when I plub the phone line into another phone or fax machine.

Fax worked for several years, just stopped working one day.

Welcome to the HP Forums,

We'll be with you until it's all sorted.

Are you using the fax on a PBX line?

If yes, you may want to contact your PBC administrator to configure an analog fax line for your printer.

If not, check the fax number, connection setup, and settings when faxes do not send.
(Once we are able to send faxes, we can resolve other issues as well)

   NOTE:

For testing purposes, you can send a fax to the HP Fax Test Service at 1-888-HPFaxme (1-888-473-2963). This free service sends a return fax within 5 to 7 minutes when the fax is working properly. Your fax number must match the number you entered in the fax header to receive the return fax.

Step 1: Print a fax test report

To begin troubleshooting, print a fax test report to identify any issues with the printer, phone line connection, or fax settings. On the printer control panel, locate Run Fax Test or Fax Test Report in the Fax or Setup menus.

Review the report for any tests that failed and follow any instructions provided. If the issue is not resolved, continue to the next step.

Step 2: Redial the number and adjust sending settings

Confirm the following dialing requirements and fax settings to help identify issues when faxes do not send. Fax setup and preferences settings are in the Fax or Setup menus on the printer control panel.

• Manually dial the fax number: From the printer, dial the number as if you are making a phone call, including the area code, the access code such as '9' to connect to an outside line, and the long-distance country code. If dialing with speed dial, confirm the saved number has required pauses between numbers (adding a dash between 9 and the area code, for instance).

• Lower the fax speed: Select the slow or standard setting.

• Turn off Error Correction Mode: Turning off this feature can improve sending success when the phone line quality is poor, but the image quality of the received fax might be unsatisfactory. If this must be turned off to send faxes, have the phone service provider check the line quality.

• Send the fax in black and white: If a color fax cannot be sent, the receiving fax machine might not support the feature.

• Confirm the dialing type (tone or pulse): Most phone lines use tone dialing.

• Enable error reporting: Turn on the Fax Error Reports feature to print a report if an error occurs when sending or receiving a fax. If the report includes a numeric error code, go to Fax Error Codes and Solutions.

Step 3: Check the connection

Check for phone line connection issues that might be causing failed sent faxes.

• Call the fax number you are sending from a phone: If you do not hear fax tones, the receiving fax machine might be turned off or disconnected.

• Confirm the fax setup: There are two phone ports on the rear the printer labeled 1-Line and 2-Ext. Connect the phone line to the 1-Line port, and connect the answering machine to 2-Ext.

  Go to HP Printers - How to Fax for steps to set up your printer.

• Check the phone line: Connect a phone to the wall jack and try to make a call. If the call fails or there is no dial tone, check if another phone or device is keeping the line open. Additionally, if you hear static, there might be interference from nearby electrical appliances (motors, fans, kitchen appliances, or televisions) and/or coax cables, or there is an issue with the line quality that requires attention from your phone service provider.

• Use the fax cord that shipped with your printer: HP fax-capable printers ship with a two-wire phone cord. If you are using a different cord, confirm the connector does not have four wires. Shorter, higher quality cords work better than longer cords of lesser quality.

  

• Remove other devices from the phone line: Devices such as answering machines, modems, or other telephones might cause faxing issues.

Additional troubleshooting

If the previous steps do not resolve the issue, reset the printer, check for any hardware related issues, and restore the default fax settings.

   NOTE:

Re-add any printer settings and preferences that were removed after a reset or settings restore.

• Reset the printer: With the printer turned on, disconnect the power cable from the rear of the printer and the wall outlet, wait 30 seconds, and then reconnect the power cable.

• Check the scanner bar functionality: Lift the scanner lid slightly, and then press the Copy button or icon to start a copy job. If the scanner light does not move or illuminate, the scanner mechanism requires servicing.

• Restore fax settings to default: Restore factory default fax settings, and then run the fax setup wizard again.
