PIXMA TR7020 "Failed to open a connection to the device (-21345)"

[cc3]

Running Big Sur on Mac Pro.  Out of the blue, printer works fine (AirPrint mode), but when attempting to now scan, I receive the message:  "Failed to open a connection to the device (-21345).  Printer is recognized as default printer in Printers and Scanners and no errors appear.  I cannot find anything online about this error now appearing. (Firewall is disabled as well.) Printer/Scanner is a TR 7020.

The problem is that canon doesn't support its products unless they're brand new, period. I have both a printer whose scanner I haven't been able to use since getting a newer laptop (discussed here), and a camera with an issues in the lens that Canon won't repair because it's "too old." These items are a decade old or less. Canon promotes a throw-away culture by refusing to fix items, update drivers, or provide support for items their customers purchased a few years ago. It's despicable and the Canon team should be ashamed of themselves. If I was a Canon employee, I'd get my fellow employees together and form a right-to-fix-it initiative to force Canon to service older items. 10 years is not old. You should do your jobs and offer service on these items.
