[LeonJersey]

As title says.

I'm trying to setup the cartridge reuse programme on Android, but I keep getting this error code:

UA_400_EB000U0405

Envy 6120e

Any ideas?

Thanks in advance

@LeonJersey, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The error code UA_400_EB000U0405 typically appears during the cartridge reuse or Instant Ink setup process when there’s a communication issue between the HP Smart app and HP servers, especially during cartridge or account authentication. Here’s how you can troubleshoot and fix this on your HP Envy 6120e using an Android device:

✅ Step-by-Step Fixes

1. Check Internet Connection

• Ensure your Android device and printer are on the same Wi-Fi network.
• Avoid using mobile data or VPNs temporarily.
• Try switching Wi-Fi networks (e.g., from 5GHz to 2.4GHz) if possible.

2. Update the HP Smart App

• Go to the Google Play Store and check for any updates to the HP Smart app.
• If already updated, consider clearing the cache and data:
  • Go to Settings > Apps > HP Smart > Storage > Clear Cache and Clear Data.

3. Remove and Re-add Printer

• Open the HP Smart app > Tap on your printer > Remove printer.
• Restart your phone and the printer.
• Re-add the printer using "Add Printer" in the app.

4. Turn off Web Services & Re-enable

• On the printer’s screen or via HP Smart:
  • Go to Settings > Web Services > Remove/Disable Web Services.
• Restart the printer.
• Re-enable Web Services and get a new claim code if prompted.

5. HP Account Issues

• Double-check that you’re signed in to the correct HP account used for Instant Ink Program.
• If unsure, try logging in via a browser at: HP Instant Ink to see if there’s any message or issue listed with your printer.

6. Try a Different Device or Browser

• If the Android device keeps giving the error, try:
  • Using a desktop or laptop browser to complete the reuse setup.
  • Temporarily install HP Smart on another Android or iOS device.

By following these steps, you should be able to resolve the error code UA_400_EB000U0405 and successfully set up your HP Envy 6120e printer.

I hope this helps.
