FIRMWARE UPDATE

5.6.2 BEFORE YOU BEGIN…
An SD card is a precision device, so always observe the following precautions
when handling SD cards:
•
Always switch the machine off before inserting an SD card. Never insert the SD
card into the slot with the power on.
•
After the power has been switched on, never remove the SD card from the
service slot.
•
Never switch the machine off while the firmware is downloading from the SD
card.
•
Store SD cards in a safe location where they are not exposed high temperature,
high humidity, or exposure to direct sunlight.
•
Always handle SD cards with care to avoid bending or scratching them. Never
drop an SD card or expose it to other shock or vibration.
Keep the following points in mind while you are using the firmware update
software:
• “Upload” means to send data from the machine to the SD card, and “download”
means to send data from the SD card to the machine.
• To select an item on the LCD, touch the appropriate button on the soft touch-
screen of the LCD, or press the appropriate number key on the 10-key pad of the
operation panel. For example, “Exit (0)” displayed on the screen means you can
touch the Exit button on the screen, or press the

button on the operation
panel of the copier.
•
Before starting the firmware update procedure, always make sure that the
machine is disconnected from the network to prevent a print job from arriving
while the firmware update is in progress.
5.6.3 UPDATING FIRMWARE
Preparation
1. If the SD card is blank, copy the entire “romdata” folder onto the SD card.
2. If the card already contains the “romdata” folder, copy the “B149” folder onto the
card.
3. If the card already contains folders up to “B149”, simply copy the necessary
firmware files (e.g. B149xxxx.fwu) into this folder.
