Hi @Jen1962,

Welcome to the HP Support Community.
 

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

The error UA_400_EB000U0422 usually appears during HP printer setup when the printer is still linked to a previous HP account or HP+ Instant Ink subscription. This prevents you from completing registration and using certain features like HP Smart printing or Instant Ink.

Here’s how to fix it step by step:

1. Why This Happens

• The printer is associated with another HP account (often from a previous owner or previous setup).
• HP+ or Instant Ink enrollment was cancelled, but the printer still expects that link.

2. Fix the Error

Option A: Contact Previous Owner (if applicable)

• Ask them to: 
  • Sign in to their HP Smart account.
  • Go to My Printers → Remove Printer.
• Once removed, you can register it under your account.

Option B: Reset Printer to Factory Defaults

• Using HP Smart App: 
  • Open HP Smart → Tap your printer → Advanced Settings.
  • Go to Settings → Restore Defaults.
• Using Embedded Web Server (EWS): 
  • Print a Network Configuration Page to find the printer’s IP.
  • Enter IP in a browser → Settings → Restore Factory Defaults.

Option C: Re-add Printer in HP Smart

• Restart the printer and your device.
• Open HP Smart → Add printer again.

3. If You Were Enrolled in HP+ or Instant Ink

• You may need to re-enroll or use standard cartridges (non-Instant Ink) for printing.
