Good day.

Unfortunately, it means that this version of the firmware has been blocked for your device by epson.

In order to restore usual functionality you can use free recovery mode firmware in WIC.

1. First enable firmware for fixing recovery mode in the settings (main menu > file > settings).
2. Start the printer in the recovery mode.
3. In the new combo box under `Fix Recovery Mode` section (the last one) select your printer's model.
