Hi @Bruce654321,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you're experiencing issues with faxing on your HP Smart Tank 7602 printer, especially with a VoIP telephone line. Here are some steps you can take to troubleshoot and resolve the problem.

• Check VoIP Settings: Ensure that your VoIP service is configured to support faxing. Some VoIP providers may require specific settings or adapters to reliably transmit faxes. Contact your VoIP provider to confirm if they support fax transmission and if any special configurations are needed.
• Filter Installation: If your VoIP provider recommends it, install a DSL filter (also known as a VoIP adapter) between the phone line and the printer. This can help improve signal quality and ensure the fax machine detects a dial tone properly.
• Phone Line Connection: Ensure that the phone line is securely plugged into the correct port on the printer (usually labeled "Line" or "Fax"). Sometimes, using a different phone cable can also resolve connectivity issues.
• Test Phone Line: Connect a regular telephone to the same phone line that the printer is using and check for a dial tone. This will verify if the issue lies with the phone line itself or the printer's configuration.
• Fax Settings: Double-check the fax settings on your HP Smart Tank 7602 printer. Ensure that the fax mode is correctly set (e.g., tone or pulse dialing) and that any required prefix numbers (such as for dialing an outside line) are correctly entered.
• Update Firmware: Ensure your printer's firmware is up to date. Sometimes, firmware updates include improvements to faxing functionality and compatibility with VoIP systems.

By following these steps, you should be able to diagnose and resolve the faxing issue with your HP Smart Tank 7602 printer connected to a VoIP telephone line.

I hope this helps.

Take care and have a good day.
