If you save program files in the USB flash memory drive and plug it into the USB direct
Interface, you can rewrite the firmware and set the country.
Note:

message described in Step (4) appears on the LCD, and check the list shown on the LCD.
(1) Save the necessary program files (such as Main firmware (djf file) and Sub firmware
(PCL/PS) (djf file)) to rewrite them into the USB flash memory drive.

machine.

The "Program Updating/ Do not turn OFF" message appears on the LCD with Status
LED on while rewriting the firmware. Do not turn off the machine.

Ready state automatically.
