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?

  • Is Preview/File/Import From Scanner active or greyed out?

  • Please can you be more specific? Do you mean from the stock Apple Preview application via the file menu? There used to be a scanner button on the printer's preference pane but it is no longer there.

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.


Try to Reset printing system:

  1. Go to  -> System Preferences
  2. Select Printers & Scanners
  3. In the left Sidebar (in the white area) do a control-click
  4. Choose Reset printing system

Looks like the universal print driver is just that - a print driver, not a scanner driver. From what it says on the page you linked, the scanner software was last updated in 2009. (I know all-in-ones are popular but I prefer standalone single function devices, as it prevents me from ending up with a unit that is 90% usable and 10% irreparably broken...)
