Check the Scanner Setup

- If there appears to be no power to the scanner, see the following article for help: There appears to be no power to the Scanner
- Check for any error lights. If a red, amber or flashing Start/Power light is displayed then refer to the scanner's user guide for further information.
- Check the USB cable connection.
- Make sure the USB cable is securely connected to the scanner and your computer, and that the cable is not damaged.
- Use a USB cable that is no longer than 1.8m.
Check Epson Scan
- Make sure your product is turned on and any interface cables are securely connected at both ends.
