If the printer is connected to the Internet, you can update the printer's firmware using the control panel. By updating the firmware, the printer's performance may improve, or new functions may be added. You can also set the printer to regularly check for firmware updates and notify you if any are available.
Select 
on the printer's control panel.
Select General Settings > Firmware Update > Update.
Enable Notification to set the printer to regularly check for available firmware updates.
Check the message displayed on the screen and select Start Checking.
Check the message displayed on the screen and select Start.
The firmware is updated when new firmware is found. Once the update has started, it cannot be interrupted.
Do not turn off or unplug the printer until the update is complete. Doing so may result in malfunction of the printer.
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.
