You can update the encryption key and create a new key. Updates are possible when the machine is working normally.
The encryption key is required for recovery if the machine malfunctions. Be sure to store the encryption key safely for retrieving backup data.
When the encryption key is updated, encryption is performed using the new key. After completing the procedure on the machine's control panel, turn off the main power and restart the machine to enable the new settings. Restarting can be slow when there is data to be carried over to the hard disk.
If the encryption key update was not completed, the printed encryption key will not be valid.
Log in as the machine administrator from the control panel.
Press [System Settings].
Press [Administrator Tools].
Press [Next] three times.
Press [Machine Data Encryption Settings].
Press [Update Encryption Key].
Select the data to be carried over to the hard disk and the one not to be deleted.
