The scanner does not turn on or turns off unexpectedly. What should I do?

• If the scanner does not turn on or if it turns off unexpectedly, try these solutions:

  • Make sure the AC adapter is securely connected to the scanner and to a working electrical outlet.
  • If the scanner turns off unexpectedly, you may need to adjust the Power Off Timer setting.
  • If you are using a USB connection, make sure the connection mode switch is set to the position (ES-300W/ES-300WR).
  • Make sure you are operating the scanner within the operating temperature range (ES-300W/ES-300WR).
  • Make sure the USB cable is securely connected to the computer.
  • Connect the scanner directly to the computer. The scanner may not work properly when connected through a USB hub.
  • Use the USB cable that came with the scanner.
  • Use a USB 3.0 (SuperSpeed) port. You cannot use a USB 2.0 or USB 1.1 port to operate the scanner on a USB power supply.
  • If the scanner does not turn off when operating on the battery (ES-300W/ES-300WR), disconnect the AC adapter and USB cable and press the reset button on the bottom of the scanner. Then reconnect the scanner and try again.
