1.1 Installing Firmware
1.1.1 Checking firmware version
Check that the firmware installed on the main PCB 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 main PCB as described in "1.1 Installing Firmware".
<How to check firmware version>
While the machine is in the ready state, press the [*] and [#] buttons simultaneously. The
firmware version information is displayed on the LCD.
1.1.2 Installing firmware using USB flash memory
Save the program file on the USB flash memory, and connect it to the machine directly to
install the firmware.
(1) Save the program files required for firmware installation (e.g. LZXXXX_$.djf) on the USB
flash memory.
(2) While the machine is in the ready state, insert the USB flash memory into the USB
memory port on the front of the machine.
(3) When the machine recognizes the USB flash memory, names of the files saved are
displayed. Press the [ ] or [ ] button to select the panel firmware file, and press the
[OK] button.
Install the panel firmware, sub firmware, and main firmware in this order.
(Start installing from the panel firmware for touch panel models, and from the sub
firmware for other models.)
(4) When "Program update/Press start" is displayed on the LCD, press the [OK] or [Start]
button. The print data lamp flashes with "Program Updating/Do not turn off" displayed,
and installation starts. Do not turn off the power switch of the machine.
(5) When installation is completed, the machine restarts automatically.
(6) Repeat steps (3) to (5) to install the sub firmware and the main firmware.
(7) When all firmware has been installed, remove the USB flash memory from the USB
memory port.
Note:
• Installing the firmware using a USB flash memory is not possible in deep sleep mode.
Press the [Start] button to quit deep sleep mode.
• Check that the there is sufficient free space on the USB flash memory before saving
the program file on the USB flash memory.
• When installing the firmware using a USB flash memory fails during the procedure
and an error is displayed on the LCD or no characters are displayed on the LCD,
change to firmware installation using a PC.
• [Touch panel models only]
When the main firmware installed is the latest version and the panel firmware installed
is not the latest version, error code 0F00 is displayed on the LCD, and firmware
installation using a USB flash memory becomes inoperable. In this case, refer to
"1.1.3 Installing firmware using PC" in this chapter to install the panel firmware.
