Soon after updating to Windows 10, many users have faced the issue of being unable to connect to their Canon printers and scanners. The majority of users have reported the Canon Scan has stopped working. The user originally stated the following on the Microsoft Forum, “Using the Canon software for Windows 10 (64bit) I press preview scan and the scanner runs through its cycle and produces a preview, I then press Scan, the scanner gets 28% of the way down the bed and stops. Scanner then hangs and it takes Task manager to end task before I can use it again. This happens with both PCs using the appropriate software and also using the Windows Scan software in Windows 10 and the free version from the App store.”
Following were the fixes reported by other users that seems to have done the trick.
Method 1: Use Canon’s MF Toolbox
Most of the users reported issues with Canon scanners so the first method deals with resolving the issue on a Canon scanner. Follow these steps:
Firstly you need to download the Canon MF Toolbox from the Canon website. Go to this link to enter your scanner’s model and follow the on-screen instructions to download the utility.
Once downloaded, install the application.
Once installed, right click on the application icon and select
Move to the compatibility tab and select the checkbox behind “Run this program in compatibility mode for”
From the drop-down list, select “Windows 8”
Now run the application and use it to send scanning requests to your scanner.
This should solve the issue for you. If not, read through our second method.
Method 2: Create a Power Plan
Some users have also found the problem to have been caused because of the USB power that was going into the scanner. If the problem only occurs for you when your computer’s power cable is plugged in (and not when it’s running on battery) then there are some problems in the USB cable.
The easiest way to fix this issue is to put your laptop on power saving mode when scanning. You can do so by clicking on the battery icon in the taskbar and clicking on Power saver. (Or you can just remove the power cable when scanning)
If you want to keep the power cable plugged in though and don’t want to set your laptop to power saving mode either, then you will need to set up a custom power plan which makes the computer think it’s running on battery. To do this, you will have to try enabling and disabling different power-saving features until you reach a combination of features where the power cable remains plugged in and the scanner works as well. To try this, you need to have a relatively high level of understanding of how the power settings work in Windows. If you are ready to do so, click on the battery icon from the taskbar and then click on Power and sleep settings.
Then scroll down to “Related settings” and click on Additional power settings.
On the left hand side, there will be an option to create a power plan. Click on it, follow the on-screen steps and see if you can make a power plan suitable enough.
