Checking firmware version

Check whether the firmware installed on the machine is the latest version. If it is the latest version, there is no need to install the firmware. If it is not, be sure to install the firmware to the machine as described in “Installing firmware”.

How to check firmware version

When the supply PCB is replaced with a new one, the machine automatically enters maintenance mode by turning it ON so the procedure below to enter the maintenance mode is not necessary.

For models without touch panel

1. Press the [Menu], and then the [Start] while the machine is in the ready state. Then, press the [▲] four times to enter the maintenance mode.
2. Press the [▲] or [▼] to display “MAINTENANCE 25” on the LCD, and press the [OK]. For keypad models, press the [2] and [5] in this order. The main firmware version information is displayed on the LCD.
3. Press the [Start] to display the version information of the sub firmware on the LCD, and then check the version information.

For models with touch panel

1. Press and hold the [Home] for approximately five seconds while the machine is in the ready state.
2. Press the blank field at the bottom of the LCD.
3. Press the [*], [2], [8], [6], and [4] on the LCD in this order to enter the maintenance mode.
4. Press the [2] and [5] in this order. The main firmware version information is displayed on the LCD.
5. Press the [Mono Start] to display the version information of the sub firmware on the LCD, and then check the version information.

Note:
You can check the sub firmware and main firmware version by implementing “Print maintenance information (Function code 77)” (refer to “Print maintenance information (Function code 77)”)

Installing firmware

Note:
Install the Sub firmware → Main firmware in this order.
DO NOT disconnect the AC cord or USB cable from the machine or computer during installing.
If the install is failed, turn OFF the machine and turn it back on. The machine enters the firmware installing mode automatically. Continue to the operating procedure below from the procedure (2).

Operating Procedure

1. If the computer is connected to the machine using the USB cable, disconnect the USB cable to enter maintenance mode. (Refer to “How to Enter Maintenance Mode”) When the supply PCB is replaced with a new one, the machine automatically enters maintenance mode by turning it ON so the procedure below to enter the maintenance mode is not necessary.
2. Connect the machine to your computer using the USB cable.
3. Open the temporary folder and double-click “FILEDG32.EXE” to start it, and select “Brother Maintenance USB Printer”.
4. Drag and drop the required program file (ex: LZXXXX_$.djf) in the same folder onto the Brother Maintenance USB Printer icon. The file is loaded to the machine, and installing to the flash ROM starts.
5. When installing is completed, the machine restarts and returns to the ready state automatically.
6. Turn OFF the power switch of the machine, and then repeat the procedures (1) to (5) to install required firmwares. 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 switch of the machine, and disconnect the USB cable.
