Hi. I recently got this Officejet 8720 at a thrift store. I want to register for instant ink but the printer states it has already been registered. I have hard reset (Semi-Full Reset) the printer but still won’t let me add it. How do I remove it from an unknown account?

Hi @ejgjunk ,

 

Welcome to The HP Support Community.  

 

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

 

I understand you are trying to remove your HP OfficeJet Pro 8720 from an unknown account and register it for Instant Ink, follow these steps:

1. Reset the Printer to Factory Settings (Full Reset)

Since a semi-full reset didn’t work, a full factory reset may help. This will erase any existing settings, including the registration information. Here's how:

  • On the printer's control panel:
    • Go to the Home screen.
    • Tap Setup (gear icon).
    • Navigate to Printer Maintenance or Restore Defaults.
    • Choose Restore Factory Defaults.
    • Follow the prompts to confirm and reset.

This should completely erase all previous registrations and settings on the printer.

2. Re-register the Printer for Instant Ink Enrolling in HP Instant Ink

After resetting the printer, you can try to register it again for HP Instant Ink:

  • Go to HP Instant Ink.
  • Sign in with your HP account or create a new one if you don’t have one.
  • Add your printer using the printer’s serial number (located on the printer’s label or in the printer's settings under About).
  • Follow the prompts to set up Instant Ink.

I hope this helps. 

 

Take care and have a good day.
