Since a while my printer, HP Officejet Pro 8620, shows that some functions have been locked by the administrator (which i am) but unfortunately i wasn’t able to unlock these.

So i went the reset route:

  • Press the “Go Back” (looks like a twisted arrow) button 4-5 times in a row
  • Press “Support Menu”
  • Hit the “down” button to “Reset” Menu
  • Hit the “down” button to “Semi-Full Reset”

This will turn off the printer. Then turn it back on and start from scratch.
