@David19579, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Let's address both issues you're facing with your secondhand HP OfficeJet 7612:

Resetting Admin Functions / Unlocking the Printer

If the printer's admin settings are locked and you can't access key functions, you can try a manual reset using the hidden support menu:

Steps to Access the Hidden Reset Menu:

1. Power on the printer.
2. Press the “Back” button (bottom left of the touchscreen) four times quickly.
   • This should open a hidden support menu.
3. Navigate to the “Reset” submenu.
4. Choose from options like:
   • Partial Reset
   • Semi-Full Reset
   • Full Reset

Alternatively, you can try this key combination:

1. Unplug the printer’s power cord.
2. Press and hold the Power button.
3. While holding the Power button, plug the power cord back in.
4. Continue holding the Power button for 10 seconds, then release.
5. On the touchscreen:
   • Press Home once (top left)
   • Press Return/Back once (bottom left)
   • Press Home twice
   • Press Menu (bottom right) → Next (top right) → Scroll to reset options

This should allow you to perform a reset and regain access to admin settings. 

Serial Number Invalid Issue

HP’s support site may not recognize the serial number if:

• The printer was previously registered to another account.
• The serial number is entered incorrectly.

Steps to Resolve:

1. Double-check the serial number:
   • Found on the back of the printer or inside the cartridge access area. 

I hope this helps. 

Take care and have a good day.
