Mimaki E109729 Overview
The Mimaki E109729 COM32 IO PCB is the input/output board of the JV300 and CJV300 printers. It handles communication between the printer and external devices, including the data connection from the computer, and passes signals to the main board. The related code E107944 is also marked for this board. This is a genuine, original Mimaki part – not a copy or compatible replacement.
Replace the IO board when the computer can no longer find the printer, when print data is interrupted or corrupted during sending, when the printer shows communication errors, or when the interface ports have been damaged. Problems after a power surge or after connecting a faulty cable are typical. Check the data cable and computer port first to rule out simpler causes before replacing the board.
