I can't start Epson TWAIN L. What should I do?
- Make sure the scanner's READY light is on. Check to make sure your USB cable is securely connected to both the scanner and computer. Try a different cable. Be sure to use an EPSON USB cable. For Macintosh, check the EPSON Scanner Selector. For Windows 98, check the Utility tab on the Perfection 640U Properties window. If you have an older EPSON scanner and have a previous version of EPSON TWAIN installed, uninstall the older version (Windows) or close any extensions like EPSON Scanner Monitor, EPSON Scanner Monitor USB, or EPSON Monitor 3 (Macintosh). If none of these solutions help, uninstall your software, then reinstall it. See the instructions for uninstalling software in your reference guide.
