Scanning is slow. What should I do?

• If scanning becomes slow, try these solutions:

  • Scan your original at a lower resolution, if possible.
  • 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.
  • The scanning speed may be reduced depending on the image adjustment features in Epson Scan 2.
  • If scanning becomes slower after scanning continuously with the ADF for a long time, the scanner may have automatically slowed down to protect the scanner mechanism from overheating or becoming damaged. Let the scanner rest with the power on for 30 minutes, then try scanning again.
  • Make sure the Slow setting is turned off on the scanner control panel. (The icon displays on the control panel when slow mode is off.)
  • 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. 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 are scanning over a network, factors such as interference, network traffic, or weak signal strength may affect your scanning speed.
  • Computers with USB 3.0 (SuperSpeed) or USB 2.0 (Hi-Speed) ports can scan faster than those with USB 1.1 ports. If you are using a USB 3.0 or 2.0 port with the scanner, make sure it meets the system requirements.
