Epson Perfection V600 Scanner not working with El Capitan

There was an update (2017-07-06) for Epson Printer Drivers v3.3 for OS X that includes what it claims are updated V600 scanner drivers. Install this, turn on the scanner, and then in System Preferences : Printers & Scanners, reset the scanner to use the updated v600 driver.

Can you scan directly from the scanner using the Apple Preview application?

Hamrick software's VueScan product supports the V600 scanner providing the Epson drivers are installed and functional. You might try VueScan as a test of the scanner drivers, though VueScan is ultimately a paid product.

I have owned VueScan for years and receive no compensation, or other favorable consideration from the vendor for mentioning it.

I did this--and now I get a pop up window from the scanner that says "the scanner is assigned to ImageCapture. Do you want to use the scanner with TWAIN?" I can't click on no or yes because I have the spinning rainbow wheel.

Any suggestions? Thank you!

Thanks so much! I did this, and that crazy pop up window is gone (for now)..but no matter what I do, the scanner does not show up in system preferences under printers and scanners. So I can't reset it.

I am able to scan if I open the Epson Scan software, but nothing happens when I try to scan directly from the scanner. If I open Epson Scan Setting from the launchpad and click test, it says my scanner is not ready, interface unknown.

So...things got busy around here and I ignored the scanner for a week. I bumped the scan button on it this morning, and it started scanning. I have no idea why it is working now, but it is. Can scan from the scanner and through the EpsonScan app. Thanks for all the suggestions! Something worked!!

Probably has to do with phases of the moon... 😁

Here is the correct answer.

Took me about an hour to find someone at Epson who actually knew how to do it. All the work arounds about restarting, and so forth don't have anything to do with it. Must have done them all about twenty times.

1. Download the ICA Scanner Driver v. 5.8.6 for Image Capture software as well as the Scanner Driver and Scan Utility V.3.9.4.0. Restart computer.

2. Open up the image capture app in El Capitan.

3. Go to file on the menu bar, then click on "reset Twain devices". Restart

4. That's all there is to it. Now you will see the scanner in the Printers and Scanner box in System preferences and

it will work in Photoshop.

Howdy Jody,

Welcome to Apple Support Communities.

It sounds like there's an issue with printer or scanner software quitting unexpectedly after upgrading your MacBook Pro to OS X El Capitan. Try taking a look at the article below and try running through the troubleshooting suggestions that it provides, the tips will resolve issues with both printers and scanners.

Take care.

Can you post the crash log here? Or at least what is crashing?

Thank you, Jody, that's plenty.

Epson's app is crashing, so they'll need to provide a fix. You may be able to workaround it though. Have you tried scanning from Preview or ImageCapture, if the device shows up in those apps? If the scanner doesn't appear in those apps, you should contact Epson to see if they have any reports of this.

I hope this helps.

And this thread:

Re: How can I get my Epson Perfection V600 scanner to work with OS X 10.9.1

says that the user was able to use ImageCapture.

Hi Jody

Try using Image Capture, it is in your Applications Folder.

FWIW I've been using Epson Printers and Scanners with my Mac's for a very long time, and I have always used Image Capture instead of Epson Scan.
