I've noticed that the scanner option has disappeared from the System Preferences (Printers & Scanners) control for the Epson AL CX21NF. I've tried installing the drivers from here and also using the System update from Apple (specific to Epson printers via the App Store). I have added the printer (using the IP address and LPD Line Daemon option) and can print to the device, but have no option to scan documents.
Has something changed in El Capitan or is this printer now just too old to be supported?

El Capitan has problems supporting scanners. After talking to Apple tecs, and Epson techs and getting the run around, my easy fix was to pay for and down load VueScan and my scanner works again.
