Using MacOS Catalina (10.15.6) the TS8220 prints correctly, but attempting to scan gives "failed to open a connection to the device (-21345)". The TS8220 has current firmware (1.010), is in same room 3' from router and 8' from iMac, on same 2G network.The scanner previously worked before upgrade to Catalina.
Suggestions what else to try or is there already a solution?? Thank you!

Hello.
Try the following adjustment to see if we can resolve this issue:
1. Go to the Home menu or press the Home button.
2. Select the Setup icon. This icon looks like a gear.
3. Select Device Settings.
4. Select LAN Settings.
5. Select Wi-Fi.
7. Select Settings.
8. Select Advanced.
9. Select TCP/IP settings.
10. Select IPv6. If you see a Yes or No question, choose Yes.
11. Select Enable/disable IPv6.
12. Choose Disable.
13. Once this has been done, turn the printer off and back on.
Next, close any applications that are open on the Mac and perform the following:
1. Click the Apple and choose System Preferences. Then open the Printer and Scanners menu.
2. Highlight and delete any copies of the Canon Printer listed on the left by clicking the minus (-) sign.
3. Click the plus (+) sign and look for an option that says "Add printer or scanner". Click this option when you see it.
4. In the next window, click Default on the upper left corner. Wait a few moments, then highlight the Bonjour version of the printer.
5. Click Add at the bottom when it becomes available.
Once the printer has been added, try accessing the "scan" tab in system preferences and see if the scanner can be opened. If the error persists, we would have to advise that you contact Apple to determine why the AirPrint scanner cannot be accessed, or scan from a different Mac/Windows computer or from an iOS/Android device with the Canon PRINT Inkjet/SELPHY app.

This has just solved the same issue which I had with my new CanonTS8351A on MacOs Monterey. I followed the instructions to disable IPV6 and the scanning is now working fine. Thanks very much.

Thanks a lot for your suggestion. It worked fine for me (iMac (Retina 5K, 27-inch, Late 2014); macOS Big Sur 11.7.4).

Since Mac's do not have a HOME MENU, your instructions are not relevant
