My computer does not recognize the product when I use a USB connection. What should I do?

• Try the following:

  • Make sure the scanner is turned on.
  • Make sure Epson Scan 2 is installed on your computer before connecting the scanner to the computer.
  • Disconnect your scanner from your computer, then reconnect it.
  • Make sure the connection mode switch is set to the correct connection type. (ES-300W/ES-300WR only)
  • If you use a USB hub, connect the scanner directly to the computer.
  • Try a different USB cable.
  • Make sure you do not use a USB cable longer than 15 feet.
  • Try using a different USB port on the computer.
