5-4. Flash ROM Writing Operation

<Difference from the BJC-50/BJC-50v>
As the BJC-55/BJ M40 does not have a parallel interface, the firmware of the Flash
ROM is written using the "USB Loader."

initial sequence finishes, another short beep will sound, the Power LED lights, and
the printer will enter the writing mode (stand-by-to-receive state.)
