Hi @Rosemud,

Welcome to HP Support Community.

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

If HP Smart is not recognizing your HP Envy 6400 series printer and you're seeing an orange/yellow triangle with an exclamation mark, it indicates that there’s an issue with the printer connection or setup. Here’s a step-by-step guide to troubleshoot and resolve the problem:

Troubleshooting Steps

1. Check Printer and Connection

Ensure Printer is On:

• Make sure your HP Envy 6400 is turned on and ready. Check the printer's control panel for any error messages or warning lights.

Check Connectivity:

• Confirm that the printer is properly connected to the network (if using Wi-Fi) or to the PC (if using USB). For Wi-Fi, make sure the printer is connected to the same network as your PC.

2. Restart Devices

Restart Printer:

• Turn off the printer, wait for about 30 seconds, and then turn it back on.

Restart PC:

• Reboot your computer to refresh its network settings and connections.

3. Update HP Smart App

• Check for Updates:
  • Ensure you have the latest version of the HP Smart app. Update the app through the app store on your device:
    • Windows: Go to the Microsoft Store, search for HP Smart, and update if needed.
    • macOS: Open the Mac App Store, find HP Smart, and update it.
    • Mobile Devices: Update through the Google Play Store (Android) or Apple App Store (iOS).

4. Check Printer Installation

• Reinstall HP Smart:
  • Uninstall and then reinstall the HP Smart app to resolve any potential software issues.
    • Windows/macOS: Go to Control Panel or Applications, uninstall HP Smart, and then reinstall it from the HP Smart website or the appropriate app store.
    • Mobile Devices: Uninstall HP Smart from your device and reinstall it from the app store.

5. Add Printer Manually

• Manually Add Printer:
  • Try adding the printer manually within the HP Smart app.
    • Open HP Smart and click Add Printer.
    • Follow the prompts to search for and select your HP Envy 6400.

7. Check Network Connection

• If using Wi-Fi, make sure the printer is connected to your Wi-Fi network. You can print a network configuration page from the printer’s control panel to check its network settings.
• If you’re using Wi-Fi Direct, ensure that the feature is enabled on both your printer and PC.

8. Perform Printer Reset

• Perform a factory reset on your HP Envy 6400 to clear any potential configuration issues.
  • Navigate to Settings on the printer control panel, find Printer Maintenance, and select Restore Factory Defaults.
