If scanning is taking a long time using the Epson Scan software, we recommend checking your firewall or antivirus software as they can be the main causes for slow or inaccurate scans.
We recommend that you check the standard firewall settings for your antivirus software and add an exception for Epson Scan (escndv.exe). As an example, the manufacturers of a popular third party antivirus software called G-Data provide guidance for troubleshooting slow scanning on their website.
If you use antivirus software developed by a different manufacturer, use the guidance below to allow Epson programs as instructed. Refer to the antivirus software documentation or online support for help on adding/allowing programs in the firewall settings.
