C. 2nd G3 PC Board Firmware
The 4 MB Program Memory (F-ROM) is integrated on the 2nd G3 PCB. The Programs for 2nd
Super G3 communication protocol Control is saved on the Board. The Firmware is transferred as
Serial Data from the SC PCB.
D. Firmware Updating Ports
Three (3) types of Ports are available for updating the firmware.
(1) Ethernet LAN Port (The Quick and Easy Method)
The machine's Firmware can be updated using a PC via Local Area Network (LAN). Refer to the
Firmware Update Operation Instructions, Service Notes (8.1.) for additional details.
(2) USB Port (Alternate)
The machine's Firmware can be updated using a PC via USB Port.
Refer to the Firmware Update Operation Instructions, Service Notes (8.1.) for additional details.
(3) SD Memory Card (New Method)
The machine's Firmware can be updated using the Master SD Memory Card. The Master SD
Memory Card can be created by copying the Firmware from the option CD-ROM using the SD
Memory Firmware Writing Tool Software and a PC with SD Memory Card Slot or with an SD
Memory Card Reader & Writer.
To update the SC PCB and 2nd G3 PCB, just one Master SD Memory Card (if the Card includes all
necessary firmware codes) is required for the Standard or all option configurations, which includes
the PCL and the 2nd G3 Fax. The easiest way is to use "Auto Mode" for updating all necessary
firmware at once.
