Widespread Scan Failure per error 21345 - unresolved too long (April 2022)

Reviewing the literally hundreds of blogs complaining about scanning malfunction via the last few MacOS updates, can be summarised as follows:

• Error 21345 is widespread across all Macs, scanner/printer brands & connection types (USB, Bluetooth, LAN).
• Everyone confirms that their printers still work but their scanners do not.
• Everyone confirms that their scanners worked fine until they upgraded to a recent MacOS.
• Cannot scan from either Image Capture or direct from Printers & Scanners via System Preferences.
• Updating scan/printer drivers has not resolved the problem.
• Turning Macs & scanner/printers on & off doesn’t fix anything.
• ‘Resetting the Printing System’ via System Preferences doesn’t fix anything.
• ‘Opening’ the printer/scanner file in Library/Image Capture/Devices/’scanner-printer name’ doesn’t fix anything either.

In summary, none of these blogger & Apple advice works, but it’s clearly an Apple failure that requires Apple to resolve & issue an update ASAP.

It’s frustrating that there is no clear acknowledgement of this failure by Apple together with a published commitment to address it & timeline.

Quite frankly, how difficult can it be to ensure the scan function continues to work regardless of any update, etc....seriously?

Now, can we please get a responsible, succinct response from an Apple professional to the basic but important issue?

Very disgruntled,
