1.2.2 Installing firmware
<Operating procedure>
(1) If the computer and machine are connected with a USB cable, disconnect the USB cable
and enter the maintenance mode. (Refer to “1.1 How to Enter Maintenance Mode” in
Chapter 5.) When the supply PCB is replaced with a new one, the machine automatically
enters maintenance mode by turning it ON so the procedure to enter the maintenance
mode is not necessary.
(2) Connect the computer to the machine with the USB cable.
(3) Open the temporary folder, double-click the “Filedg32.exe” to start, and select “Brother
Maintenance USB Printer”.
(4) Drag and drop a necessary program file (ex: ******_$.djf) located in the same folder to the
Brother Maintenance USB Printer icon located within the FILEDG32 screen. The files are
sent to the machine and installation into the flash ROM is started.
(5) When installation is completed, the machine reboots and returns to the ready state.
(6) Turn OFF the power of the machine, and repeat the procedures (1) to (5) to install
necessary firmware. However, when the supply PCB is replaced with a new one, the
machine automatically enters maintenance mode by turning it ON so the procedure (1) to
enter the maintenance mode is not necessary.
(7) Turn OFF the power of the machine, and disconnect the USB cable.
<Firmware installation failure>
If the firmware installation fails due to “a power blackout during installing” or “the USB cable
was disconnected during installing”, turn OFF the machine and turn it back on. Then repeat
the procedure from (1) of <Operating procedure> above.
