Recently I've buyed a HP 9020 Multi-function printer. Yesterday, it got automatic updates and now I can't to change that option. When I try to do it, the following message is showing: " Feature locked - This feature has been locked by teh person who setup the printer". The path to change it is: Setup > Printer maintenance > Update the printer > Printer update options (the Auto option is grayed and when I pick up that option appears the above message).
I need to downgrade the firmware and I also need to take control of when automatic updates occurs.
