Updating Firmware without Connecting to the Internet

You can download the device's firmware from Epson website on the computer, and then connect the device and the computer by USB cable to update the firmware. If you cannot update over the network, try this method.

Note:

Before updating, make sure that the scanner driver Epson Scan 2 is installed on your computer. If Epson Scan 2 is not installed, install it again.

  1. Check the Epson website for the latest firmware update releases.

    • If there is the firmware for your scanner, download it and go to the next step.
    • If there is no firmware information on the website, you are already using the latest firmware.

  2. Connect the computer that contains the downloaded firmware to the scanner by USB cable.

  3. Double-click the downloaded .exe file.

    Epson Firmware Updater starts.
