Epson is not noted for keeping their drivers for older devices up to date with the rapid evolution of OS X, but that is their problem, not Apple's. That is a major reason why the Open Source
Gutenprint was developed for printers and at least part of the reason Hamrick developed
VueScan for Scanners. You might check VueScan's
list of supported scanners to see if your Epson is on it and if so give VueScan a try. It has been highly recommended for years.
