I tried everything I could find to fix this problem except for (a) replace my canon p-150 and (b) switch computers. Solutions I already tried that did not work: And now, (last 3 days), I couldn't get the scanner to work. (about 3 weeks ago) I had to reboot he computer multiple times. After the Windows 10 update, I was having to reboot the computer every time I needed to use the scanner. Fast forward a couple of years and Microsoft eventually got me to upgrade to Windows 10. I searched the internet for a solution and when I couldn't find one I resigned myself to rebooting the computer every once in a while. When this problem first popped up, all I needed to do was reboot my computer and everything would work. Check that another application is not using the device.' Occasionally I would try to use the scanner after being away from the computer for a while and I would get 'Error -4630: The device could not be locked. Back then, my computer was running windows 7.

When I first setup the scanner it worked perfectly for some time. It is an inexpensive multisheet duplex scanner.

I feel compelled to share my solution and I hope it works for you. For 4 years I have been dealing with this problem! I finally found a SOLUTION!!! I have read this thread at least 40 times hoping someone would post a solution that would work for me.
