Updating the Encryption Key
You can update the encryption key and create a new key. Updates are possible when the machine is
functioning 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 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.
