1.1.3 Rewriting the firmware using USB flash memory
If you save the program files in the USB flash memory drive and plug it into the USB direct
interface, you can rewrite the firmware.
<Procedures>
(1) Save the program files (such as LZXXXX_$.djf) which are necessary for rewriting the
firmware to the USB flash memory.
(2) While the printer is in the ready state, connect the USB flash memory drive to the USB
direct interface on the front of the printer.
Fig. 4-1
(3) When the printer recognizes the USB flash memory, the names of the files stored in the
USB flash memory are displayed. Select an appropriate file using the or button,
and then press the Go or OK button.
(4) “Program Update/Press Go” appears on the LCD. Press the Go or OK button to start.
“Program Updating” message appears on the LCD with Data LED blinking while rewriting
the firmware. DO NOT turn off the printer.
(5) When the rewrite is finished, the printer automatically restarts.
(6) If you continue to rewrite other firmware and no file names are displayed, wait for a while,
and take out the USB flash memory and insert it again. When file names are displayed,
select the program files which need to be rewritten, and repeat the above procedures (3)
to (5) to rewrite all the selected program files.
(7) When the rewrite of the main firmware is finished, the printer automatically restarts.
(8) Remove th
e USB flash memory drive from the USB direct interface once the update have finished.
Note:
- You cannot write the firmware using USB flash memory in the Deep Sleep mode. Press
the OK button to clear the Deep Sleep mode before rewriting the firmware.
- Make sure that the USB flash memory drive has enough space to save the program file.
- It is recommendable to rewrite 1) Sub firmware and 2) Main firmware
in this order.
- If rewriting the firmware using a USB flash memory fails and an error message appears
on the LCD, or no message appears on the LCD, it will be necessary to rewrite the
firmware from a computer using the “FILEDG32.EXE”. (Refer to “1.1.2 Rewriting the
firmware using computer” in this chapter.)
- The printer driver of the relevant model must have been installed.
Memo
To print and check the list of data stored in the USB flash memory, display the LCD,
select Index Print using the or button, and then press the Go or OK button.
