1.1.3 Rewriting the firmware using USB flash memory
(USB direct interface model only)
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.
When a USB flash memory is used, the following firmware files are needed to rewrite the
firmware.
<Procedures>
(1) Save the program files (such as LZXXXX_$.djf) which are necessary for rewriting the
firmware that are prepared in the temporary folder to the USB flash memory.
(2) While the machine is in the ready state, connect the USB flash memory drive to the USB
direct interface on the front of the machine.
Fig. 6-1
(3) When the machine recognizes the USB flash memory, the names of the files stored in the
USB flash memory are displayed. Select an appropriate file using the or button,
and then press the OK button.
Sub firmware (PCL/PS) LZXXXX_$.djf
Main firmware LZXXXX_$.djf
LZXXXX: First six digits are a parts number of the firmware.
$: Alphabet representing the revision of the firmware.
Note:
- Make sure that the USB flash memory drive has enough space to save the program file.
- It is recommendable to rewrite 1) Sub firmware (PCL/PS) 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.)
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 OK button.
