In the C228 DRV board, E05B48(IC9) plays its central role. On this board, 2 printing heads, 3 motors and solenoids, and all sensor circuits are mounted.
These driving/stop signal, monitoring the conditions of all sensors in the motive power line, and the control in the driving line according to the conditions are
determined by E05B48 through communication with C228 main board. Figure below shows block diagram of C228 DRV board.
