@Darkbiped, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Error Code UA_400_EB000U0422! 

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

The error code UA_400_EB000U0422 on your HP Envy series printer typically indicates a connectivity or configuration issue during the setup process. It may happen if the printer cannot establish a stable connection with your Wi-Fi network, or if there’s an issue with the printer's communication with the HP app or servers.

Here are a few steps you can try to fix it.

Check your Wi-Fi Connection:

• Ensure that your printer is within range of your Wi-Fi router.
• Make sure that your Wi-Fi network is active and stable.

Restart the Printer and Router:

• Power off your printer and unplug it from the power source for about 30 seconds, then plug it back in and power it on.
• Restart your router to refresh the network connection.

Update the HP Smart App:

• Make sure that you’re using the latest version of the HP Smart app on your device.
• Go to your app store and check for updates to the HP Smart app.

Re-run the Setup:

• If the setup process was interrupted or failed, try running it again after restarting both your printer and the app.

Check Printer’s IP Address:

• Ensure that your printer is connected to the same Wi-Fi network as your device running the HP Smart app. You can print a network configuration page from the printer to verify its IP address and connection status.

Disable Security Software/Firewall:

• Sometimes, firewall or security software may block the connection. Temporarily disable these and try the setup again.

Try a Different Device:

• If the issue persists, try setting up the printer on a different phone, tablet, or computer with the HP Smart app.  

Hope this helps! 

Take care, and have an amazing day!
