Hi @edwmar,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

If you're always getting a busy signal when trying to send a fax from your HP Smart Tank 5105 on Windows 11, here are some things to check:

Verify the Fax Number

• Double-check that you are dialing the correct fax number.
• Ensure you are including any necessary area codes or prefix numbers required by your telephone provider.

Check for Line Issues

• Pick up a regular phone connected to the same phone line and try calling the fax number manually.
  • If you hear a busy signal, the issue is with the recipient’s fax line (not your printer).
  • If you hear a fax tone, it means your printer is not sending the fax correctly.

Check Your Phone Line Setup

• Make sure the phone line is working properly. Try plugging a regular phone into the same wall jack and listen for a dial tone.
• If you have VOIP (Internet-based phone services like fiber, cable, or VoIP services like MagicJack, Vonage, or a digital phone service), make sure:
  • Your fax machine is connected to the correct fax port on your router.
  • You are using a standard telephone cord, not a DSL filter.
  • The phone service supports faxing. Some VoIP services do not support fax transmission properly.

Check Fax Settings

• Make sure the line is set to ‘Tone’ and not ‘Pulse’ dialing.
• Lower the baud rate (transmission speed) in your fax settings. Some phone lines may not support high speeds.
  • On the printer control panel, go to Fax Settings → Fax Setup → Fax Speed and select Medium (14,400 bps) or Basic (9,600 bps) instead of High (33,600 bps).
• Enable Error Correction Mode (ECM) in the fax settings.
• If you use a DSL internet service, make sure you are using a DSL filter.

Test with a Different Number

• Try faxing to a different number to check if the issue is only with one specific recipient.
• If your printer has a built-in self-test feature or fax test report, use it to diagnose issues.

Check for Firmware Updates

• Go to the HP Support website and enter your printer model (HP Smart Tank 5105).
• Download and install any available firmware updates for the printer.
