Unable to register Envy 6120e printer to account for instant ink. Error Code: UA_400_EB000U0422

Unable to register Envy 6120e printer to account for instant ink. Message says Printer registered to another account. Error Code: UA_400_EB000U0422.  Inadvertently set up the printer with a US account.  Opened a UK account for instant ink and used different email but I keep getting the above message.

Hi @Ethelreda,

Welcome to the HP Support Community.
 

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

I can see why this is frustrating. Instant Ink is supposed to make printing easier, not harder! The error UA_400_EB000U0422 means your HP Envy 6120e printer is still linked to the original HP account (in this case, the US account), and HP doesn’t allow a printer to be registered to two accounts at the same time.

Here’s the official HP way to fix this:

Step 1: Remove Printer from Old Account

• Sign in to the original HP account (the US one you used first).
• Go to My HP Instant Ink → Manage Printer → Cancel Subscription / Remove Printer.
• Wait for confirmation that the printer is removed.

Step 2: Factory Reset the Printer

• On the printer control panel: 
  • Setup → Printer Maintenance → Restore → Restore Factory Defaults.
• This clears previous account data.

Step 3: Reconnect Printer to New Account

• Sign in to your UK HP account.
• Open HP Smart app → Add Printer → Follow setup steps.
• When prompted, enter your Instant Ink enrollment details.

Important Notes

• If you cannot access the old account, you’ll need HP Support to unlink the printer manually.
• Contact HP here: 👉 HP Instant Ink Service | HP® Support

I hope this helps.

Take care and have an amazing day!
