I'm sorry about the issue. Canon did not make a driver for your printer model for Windows 10, but you can download and install the Windows 8 printer driver, and it will work on your windows 10. Please try the following fix:
1. Right-click on the Start button (which is the windows logo icon at bottom left of computer's screen), then click on Control Panel (or press at the same time the two keys Windows and R on the keyboard, then type control then click OK), then open System and Security / System, and note if the System type is 32-bit or 64-bit.
2. Click on the Canon website below:
, then there, for Operating System, select Windows 8 (x64) if system type is 64-bit, or select Windows 8 if system type is 32-bit
, then click on Drivers below it
, then download and install the item MP620 series Mini Master Setup, then it should work
, (if it does not work, then download and install the item MP620 series MP Driver)
Please reply at the box below to continue troubleshooting. Thank you.
