Download and extract the necessary firmware from "ROM/Firmware DB", then copy it to the
"AML" folder created in C drive.
(1) Connect the USB cable to the printer. Turn on the printer while pressing Go and Job
Cancel keys. (The USB serial number is fixed to "987654321".)
The LCD shows [SELF TEST] -> [RAM SIZE = 32MB] -> [Now Initializing] -> [LINETEST
MODE] in this order. Keep pressing Go and Job Cancel keys until [LINE TEST MODE]
appears and release the keys after confirming it.
The LCD shows [WARMING UP] -> [READY] in this order. Wait until [READY] is
displayed.
(2) During the step (1), Plug and Play will run to install the USB driver of relevant model.
(3) Double click "FILEDG32", which is in the "AML" folder. Then, drug and drop the firmware
(61_$$$.BLF or 71_$$$.BLF) to the printer icon in FILEDG32.
Data is sent to the printer via the USB cable, and start writing. While the data is sent to
the printer, DATA LED blinks and when firmware rewriting starts, LED display changes.
Even if transfer command is completed, the data is still transmitted or the rewriting
procedure continues. Therefore, be sure NOT to shut down the Windows system, turn the
printer off, unplug the cable and turn the computer off until it reaches to the condition of
step (4). Re-writing may be impossible once the writing procedure fails.
(4) After the rewriting finishes, the printer will be rebooted. Wait until Status LED of the printer
turns on in green. After rebooting, Copy2 icon of the printer is created in a printer folder.
To avoid unnecessary mistake, delete the icon.
