Notes for enabling encryption settings
• If you use Embedded Software Architecture application, be sure to specify [File System Data
Only] or [All Data].
• Note that the machine's settings will not be initialized to their system defaults even if [Format
All Data], [File System Data Only], or [All Data] is specified.
Restoring Data
• To transfer data to a new machine, restore the encrypted data. For details, ask the service
representative.
• The encryption key used for data encryption is required to restore the data.
• You can specify whether to print the encryption key or store it on an SD card.
• You can change the encryption key later.
Enabling the Encryption Settings
• The machine cannot be operated while data is being encrypted.
• Once the encryption process starts, it cannot be stopped. Make sure that the machine's main power
is not turned off while the encryption process is in progress. If the machine's main power is turned
