I can't start Epson Scan 2. What should I do?

If you cannot start Epson Scan 2, try these solutions:

• Make sure your scanner is turned on and any interface cables are securely connected at both ends.
• Make sure your computer is not running in a power-saving mode, such as sleep or standby. If so, wake your system and restart Epson Scan 2.
• Connect the scanner directly to the computer. The scanner may not work properly when connected through a USB hub.
• If you connected the scanner using a USB cable, make sure it is connected directly to your computer or through only one USB hub.
• Make sure you do not have multiple versions of Epson Scan 2 installed. If you do, uninstall all versions and install one version.
• If you are using the scanner with the optional Epson Network Interface Unit, make sure the network cable is securely connected.
• If you upgraded your operating system but did not reinstall Epson Scan 2, try reinstalling it.
• If you are using a TWAIN-compliant program, make sure that the correct product is selected as the Scanner or Source setting.
