Hi dinosaurs! Thanks for posting in the Canon Community Forum. I see that you are unable to use your CanonScan LiDE 120 by clicking on the buttons in the IJ Scan Utility (nothing happens) installed on a Windows 10 computer.
I see you can scan when using the Windows Fax & Scan program. In most cases, that does mean the scanner is properly connected. If you have not done so, I recommend turning your computer off (shutting it down completely) and then turning it back on.
You also mentioned that you have tried reinstalling and selecting the “Run as Administrator” option. I assume that you are running the CanoScan LiDE 120 Scanner Driver Ver.1.03 (Windows). The name of that file (as it appears in your Downloads folder) should be sc68-win-lide120-1_03-ea33_3.exe. If you are running a different file, please visit the following website and download the CanoScan LiDE 120 Scanner Driver Ver.1.03:
https://www.usa.canon.com/support/p/canoscan-lide-120
Once the program has finished downloading, please run it (and you can select the Run as Administrator) option.
If your computer has multiple User Accounts, I recommend testing the Scan Utility on a different user account (including the Administrator Account). If you can use the IJ Scan Utility when logged in as a different user, there is likely a user setting that is keeping you from using the IJ Scan Utility on that other account.
I see by your screenshot that the CanoScan LiDE 120 is already selected next to the Product Name. That window should respond when you click on the Settings button. If you have not done so, please try clicking on the button that says “Settings…” and see if the Settings window opens.
If the Settings window does open, but nothing happens when you click on the Auto, Document, Photo, Custom, Stitch, or ScanGear buttons, it is very likely that a security program or computer setting is interfering with the IJ Scan Utility. If you do have a security program, I recommend that you contact the software developer and have them help you make an exception for the IJ Scan Utility. The location is as follows:
c:\Program Files (x86)\Canon\Scan Utility\SCANUTILLA.exe
If the Settings window does not open when you click on the Settings button or if there is no security program interfering with the use of the IJ Scan Utility, I recommend contacting Microsoft support for Windows 10. Please have them check if there is a computer setting that is keeping you from using the IJ Scan Utility. You can also contact the computer’s manufacturer if you prefer.
To troubleshoot further, please make sure that you are using a USB cable that is no longer than 6 feet. Additionally, please make sure that the cable that is connected directly to a USB port on your computer (not to a hub) and that you are not using an adapter. If you have a desktop computer, please make sure the cable is connected to a USB port on the back of the computer.
Next, we recommend installing the scanner on a different Windows computer (preferably one that is not using the same security software). You can download and install the CanoScan LiDE 120 Scanner Driver Ver.1.03 (file name sc68-win-lide120-1_03-ea33_3.exe) from the website mentioned above. Then, please come back and let us know if you can use the IJ Scan Utility with a different Windows computer. In your reply, please include details regarding the troubleshooting efforts mentioned in this post.
I hope this information helps. Thanks for choosing Canon.
Danny
