I have a Epson scan that after an update is not compatible with my computer.

Hi sig272,

Thank you for posting in Apple Support Communities! You'll want to check with the manufacture to confirm compatibility with macOS Monterey and your scanner model. You should also be able to get any firmware updates that may need to be installed.

You can visit the Epson support site for macOS Monterey here: Epson.

Have a good one!

When you share that you are having issues with your scanner, you might be helped if you tell us the exact make and model number of the scanner, because we will need that going forward to research if there is a solution for you or not.
