When Initial Charge is not needed when replacing the Main Board
with a new one, make sure to execute “Initial Ink Charge Flag ON/
OFF” (p315) before updating the firmware.
(The printer is rebooted automatically right after uploading the
firmware. Since the parameter does not exist on the new Main
Board, the ink initial charge operation starts automatically.)
