Updating Firmware
By renewing the firmware (print controller: system software, network controller: network firmware) you can
update the control program without having to replace the system board. In addition, you can replace either
the print controller or network controller firmware if they become damaged and fail to operate correctly by
overwriting the system software and network firmware to restore them to their original state.
The firmware is updated/replaced using the parallel port.
●
