Fax suddenly stopped getting a dial tone

[MGinSB]

I have optimum Altice and have been able to fax in the past. However suddenly I am not able to get a dial tone. I troubled shooter the line by connecting a phone and that was able to get a dial tone. But the fax machine is not able to send or receive faxes. Any advice?

@MGinSB Check the fax number, connection setup, and settings when faxes do not send.

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.
