When Replacing the Main Controller PCB
(LBP3580/6780x)
The Flash ROM of the Main Controller PCB contains the following data.
• Firmware: Boot module for startup, main program Bootable
• Setting values: User mode setting values, service mode setting values
• Management data: Page counter data, device serial number
• MEAP applications
In a case of replacement with a new Main Controller, it is necessary to migrate the setting
values from the old Main Controller.
The data can be exported by executing service mode > function.gr > ALL, and the order of
priority for exportation is shown below.
USB memory device (when a USB memory device is connected) > SD Card (when a SD
Card is connected) > RAM (when none of them is connected)
MEAP applications cannot be migrated and need to be installed again.
The data migration method and the target data at the time of replacement of the Main
Controller PCB are shown below.
