I can't select some Epson Scan buttons because they are grayed out. What should I do?
You can use Epson Software Updater to update Epson Scan, if it is available for your product. To install Epson Software Updater, go to the Epson support page, select your product, then select Downloads > Utilities > Epson Software Updater. Download the software, then follow the on-screen instructions to install it.
