If the printer can be connected to the Internet, you can update the printer's firmware using the control panel. You can also set the printer to regularly check for firmware updates and notify you if any are available.
Select Settings on the home screen.
To select an item, use the 
buttons, and then press the OK button.
Select General Settings > System Administration > Firmware Update > Update.
Select Notification > On to set the printer to regularly check for available firmware updates.
Check the message displayed on the screen and start searching for available updates.
If a message is displayed on the LCD screen informing you that a firmware update is available, follow the on-screen instructions to start the update.
Do not turn off or unplug the printer until the update is complete; otherwise, the printer may malfunction.
If the firmware update is not completed or is unsuccessful, the printer does not start up normally and "Recovery Mode" is displayed on the LCD screen the next time the printer is turned on. In this situation, you need to update the firmware again using a computer. Connect the printer to the computer with a USB cable. While "Recovery Mode" is displayed on the printer, you cannot update the firmware over a network connection. On the computer, access your local Epson website, and then download the latest printer firmware. See the instructions on the website for the next steps.
