1. Download the projector firmware file from the Epson support website. Make sure it is the correct
firmware file for your model.
Note: If the firmware file is not the correct file for your model, or if you renamed the file, the update
will not start.
2. Turn on the projector.
3. Connect the USB cable to the computer's USB port and to the projector's Service port.
4. Press the Menu button, select Initial/All Settings > Firmware Update and press Enter.
5. Select Yes to start the firmware update.
Note: Do not disconnect the power cable or remove the USB cable while the firmware is updating.
All of the status indicators on the projector turn on and the projector enters firmware update mode.
The projector appears as a removable drive on the connected computer.
Note: If the projector is in firmware update mode for longer than 20 minutes before a firmware
update starts, it automatically shuts off. Return to step 2 and repeat the process.
6. Copy the downloaded firmware file onto the root (top) directory of the projector's removable drive.
Note: Do not rename the firmware file.
7. Safely remove the projector's removable drive from the computer, then disconnect the USB cable
from the projector.
The firmware update starts.
While the firmware is updating, the status indicators on the projector start flashing and the cooling fans
run at high speed (this is normal). After the update is complete, the projector enters standby mode. If
Direct Power On is enabled, the projector restarts automatically.
Note: If all status indicators flash rapidly, the firmware update may have failed. Disconnect and
reconnect the projector's power cord. If the indicators continue to flash even after reconnecting the
power cord, unplug the cord from the electrical outlet and contact Epson Support.
After the update is complete, check the Version setting in the Management > Information menu to
confirm that the firmware was updated successfully.
