7.3 Parameter Backup
This section describes how to back up various parameters.
The NVRAM (Flash-Rom and EEPROM) installed on the MAIN board assembly stores various
parameters for the system operation.
The available backup parameters are as follows.
• Panel settings
• Mechanism adjustment parameters
• Main board-unique adjustment parameters
TIP
The MAIN board-unique adjustment parameters cannot be erased and modified.
If the MAIN board assembly is found to need replacement in service operations, make sure to back up
the system parameters before replacing the board. The backup data can be used to restore the original
system status, eliminating some adjustment steps.
CAUTION
Before backing up the system parameters, always ensure that the machine power
is OFF. Parameter backup with the machine power ON may damage the MAIN
board or prevent correct parameter restoration.
7.3.1 Jigs and Tools
The following jigs and tools are required for parameter backup.
• Flash memory card
TIP
• For further details on the jigs and tools, refer to "10.3 Jig and Tool List".
Note that the flash memory card used for parameter backup should not be used for any other purposes.
