Hi caliki,
Thanks for posting this help! But I still get "Unable to save scanned files" error message. Using an Epson Perfection V850 Pro (circa 2016) connected to iMac 2017 running Monterey 12.6.3.
I downloaded Uninstall from the Epson site, ran that and uninstalled a bunch of stuff, then downloaded the main installer package at top of Epson site (ignoring various individual installers beneath), installed, then restarted the iMac. Nada. Didn't work. I must be missing some key step ...
On the Epson site, there are so many drivers to install that it's a little confusing. There is one big package at top, then various separate drivers, below. Do you recommend downloading the separate drivers, instead?
Thanks so much for all of your help!
