'Unlock the hardware lock' message
I get a message on my screen, 'unlock the hardware lock' when trying to scan. The lock is in fact, unlocked. Have physically moved the switch back and forth. Scanner has been sitting in the same location, but not used for about 6 months

Does the scanning carriage move at all when the scanner is starting up? If not, then it might have stuck and needs to be moved back and forth a couple of times manually to loosen in, with the power not applied of course, and for that you would have to remove the glass most probably.
Also observe if the belt that moves it is properly attached to the carriage, placed over the motor gear and the support gear at the other end.
Of course the motor itself might have failed, or it's control electronics.
Found the answer to my problem, my p[problem getting inside the 8920. You need to remove the two small rubber pads on the top of the machine on the left side as you face it. You also need to remove the two screws under the front panel. With thse fpur screws out, lift the left side and it will tilt up to the right and you can unhook the right side. You are now in the machine..
