Question about HP OfficeJet 9120 All-In-One InkJet Printer
If you opened the lid in the same manner as you would to replace the ink cartridges and made sure that the switch on the right side underneath the lid was in fact unlocked, turned off the unit, waited a moment (up to 60 seconds) and turned the unit back on, but still receive the message saying that your scanner is locked, then you will need to use a Phillips screwdriver to remove the top cover and make sure that the scanner head is not somehow jammed. Usually you can hear the gears and motor spin up when the scanner head is unlocked. If you cannot, you may have a bad scanner head.
