Hi! Thanks for posting in the Canon Community Forum. I see that you need to scan from your PIXMA TS6420a to a Windows 8 computer.
The TS6420a is not compatible with Windows 8, but we do have software and drivers for Windows 8.1. Please check your computer’s operating system. If it is running Windows 8.1, please go to the following website to find the TS6400 series MP Drivers:

Once the page is open, please click on SOFTWARE & DRIVERS to the right of the picture of the printer, and then make sure the Operating System and Version is set to Windows/ Windows 8.1 (X64). Next, scroll to the bottom of the list and click on LOAD MORE. Then, you can look for the TS6400 series MP Drivers. This driver option contains the scanner driver and the IJ Scan Utility.
If your computer is running Windows 8 (and not 8.1), you may be able to use the Windows Fax and Scan app. Most computers since Windows 7 have had this app installed. If you don’t see this app in your computer’s list of programs, I recommend checking to see if you can download it from the Microsoft website.
You may also be able to scan using the Paint program on your computer. Once you open Paint, you can do the following:
- Click on the FILE button.
- Select FROM SCANNER OR CAMERA in the menu that drops down.
- Select the scan settings.
- Start scanning.
I hope this information helps. Thanks again.
