• Make sure your system meets the requirements for your operating system. If you are scanning a high-
resolution image, you may need more than the minimum requirements. If necessary, increase your
system's memory or reduce the resolution.
• If you are running virus protection or other security software, exclude the TWAIN.log files from
monitoring or set the TWAIN.log file as read only (Windows). See your virus protection or security
software instructions for details. The TWAIN.log file is saved in C:\Users\(user
name)\AppData\Local\Temp.
Note: You may need to unhide system folders to view files in that location.

If you have problems scanning over a network, try these solutions:

after installing the scanning software. Also start Epson Scan 2 before scanning with the start button.
