When the printer can connect to the Internet, you can update the firmware from Web Config.
Access Web Config and select the Device Management tab > Firmware Update.
Click Start, and then follow the on-screen instructions.
The firmware confirmation starts, and the firmware information is displayed if the updated firmware exists.
You can also update the firmware using Epson Device Admin. You can visually confirm the firmware information on the device list. It is useful when you want to update multiple devices' firmware. See the Epson Device Admin guide or help for more details.
