Guide: Fix Epson Scan Not Responding Windows 10 (2018) - V300 V600 V700


The 2018 "feature update" for Windows 10, also known as Update #1803, breaks the Epson Scan Utility software. This affects all compatible devices including Epson's dedicated line of scanners from the V300 to the V600 on up.

When the problem occurs, you'll see a small Epson window flicker in the bottom corner of the screen and sometimes bounce around sporadically. The app locks up and your only recourse is to terminate the software through the Task Manager and then power your device off and on again. This happens most commonly after switching to a different application and then back.

Epson has acknowledged that this problem affects most of their products and they've reportedly escalated the matter. Until a fix becomes available through Epson or Microsoft, the quick fix is to simply run it in administrative mode. Here are the complete steps:

  1. Download the latest Epson Scan package from Epson's website for your respective device. You can find the correct download by entering the device's model number into the site and then clicking on the "Support" link. From there, locate Scanner Driver and EPSON Scan Utility and click "Download." If a security warning pops up, click "OK" or "Keep" to download the file to your computer.
  2. Once downloaded, install the program to your computer using the default options. This process will place a new shortcut to the software on your desktop, which will make the next steps a little easier. If asked to restart your computer, please do so.
  3. Right-click on the Epson Scan shortcut on your desktop and select "Properties."
  4. Click on the "Compatibility" tab.
  5. Click the button at the bottom labeled: "Change Settings for All Users" and if prompted for confirmation, click "Yes."
  6. Check the option "Run this program as an administrator."
  7. Click "OK," then "OK" again to close the properties.

You should now be able to launch Epson Scan Utility again and use it without issue. Depending on your user account settings, you may have to click "Yes" if prompted with a security alert.

The first time you launch the application after making these changes, you may also receive a "compatibility alert." Select "Yes, this program worked correctly" to close it.

Addendum - No Icon on Desktop

If you do not have a scan icon on your desktop, you can modify the executable directly. To do this:

  1. Press WINDOWS KEY + R to open the Run dialog.
  2. Enter: c:\windows\twain_32\escndv\ then press Enter or click "OK."
  3. When the Explorer window appears, right-click on the escndv.exe icon and select Properties. Then you can continue the tutorial as described above.

Addendum - Disable Security Prompt on Launch

If you have User Account Control enabled, you'll receive a confirmation box each time you launch the app in administrative mode. Although a minor nuisance, there are a couple solutions.

When the alert appears, you can click on "Show More Details" and then "Change when these notifications appear." From there, you can lower the level to the second notch to still receive the alert but without dimming the entire desktop. You can alternatively set the option to "Never Notify" to remove the alert entirely. Be aware that this is a global setting and unless you are an advanced user I don't recommend disabling it, since the alerts can help prevent malware installation.

A more intelligent solution is to use a third party utility or the task scheduler to disable the alert on this application exclusively. Since this can be a somewhat more involved process, I will refer you to an excellent tutorial from, which thoroughly covers numerous methods of doing so.

  1. Thanks for this article. I couldn't figure out why my V700 worked just fine 3 weeks ago but now chokes after running the prescan.

  2. Hey, Thanks!

    You are absolutely spot on. This is the first time in my life I've had a software/hardware/website/etc. issue and found the EXACT solution for MY problem right away.

    Thanks again for the help.

  3. I'm keeping my fingers crossed - but that does seem to have allowed the scan to respond properly

    Thanks Matt - much appreciated

  4. Thank you Matt! I have the WF-2750 and this worked. You would think Epson would have told me to do this when I contacted them. I use my scanner Mon-Fri and it has been very frustrating.

  5. Hello Matt, I have an Epson Stylus Office TX510FN MFP running Windows 10 ver 1803; after changing to "Run this program as an administrator.", the Scanner worked perfectly for one day.

    On second day, the earlier problem has recurred again: after one scan, flickering is seen in the windows icon at the bottom left corner of the screen and then the scanner software crashes. I have to reboot the scanner before the Scanner software runs and keeps crashing after one scan.

    Can you please guide me to fix it?

    • Hi Satish, first double check that under the icon's properties you have changed it via "Change Settings For All Users" and before checking "Run As Administrator" as otherwise there may be some oddities like this.

      If that is set and still happens, you may want to navigate to the directory of the scan software manually and then set these same permissions on all of the EXEs directly. For most scanners the software is in "C:\windows\twain_32\escndv\" and there may be four or more EXEs that you can adjust (you may have to set "Show File Extensions" to see which is an EXE).

      Finally, if the problem still persists then consider also setting the EXE to run in "Windows XP Service Pack 3" which should solve it but could break the "Browse for Folder" option so you'd want to configure where the scans are saved beforehand. You could try "Windows XP Service Pack 2" if that still gives you grief.

      Other than that I don't have much advice I haven't heard of this happen before but also don't have that device or specific drivers to test directly. Good luck! Epson has slowly been rolling out some fixes for some of their newer products but older ones still have this issue and require the workaround.

  6. This is not solving the issue for me on my XP-610. Setting the scan location ahead of time isn't possible because clicking that button causes the lock up.

  7. Follow up. Epson Support sent me these directions and they worked!

    Although you may have tried these steps, we believe the following will resolve your issue.
    Launch Epson Scan (if applicable).
    Under Home or Professional mode, please click on Configuration at the bottom part of Epson Scan.
    On the Configuration window, click on the Other tab, and click on Reset All.
    Confirm restoring of Epson Scan.
    Launch the Epson Scan program again and try to use the Preview option.

  8. Thank you sooo much for sharing your knowledge! Such a simple solution to what's been driving me mad for months re-starting my PC just to scan once at a time. Was on on the verge of packing it up and returning to the shop!! Fantastic!
