5.2.2 FIRMWARE UPDATE PROCEDURE
This section illustrates how to update the firmware.
To update the firmware, you must have the new version of the firmware downloaded onto an SD
(Secure Digital) Card. The SD Card is inserted into the uppermost slot on the right side of the
controller box, viewed from the back of the machine.
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.
 When the power is 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 screen, press the appropriate key on the operation panel, or
press the appropriate number key on the 10-key pad of the operation panel.
 Before starting the firmware update procedure, always make sure that the machine is
disconnected from the network to prevent a print job for arriving while the firmware update is
in progress.
