Starting the use of the data encryption feature and changing the settings
When data encryption is started or ended, or when the encryption key is changed, the

The recording area stores the following data.
- Spooled print data
- Print data including secure print and sample print
- Forms for the form overlay feature
- Mailbox and job flow sheet settings (box name, passcode, etc.)
- Documents in mailboxes
- Address book data
Important • Be sure to save all necessary settings and documents before starting to use the data
encryption feature or changing the settings.
• An error occurs if the connected hard disk does not match the encryption settings. For
information on error messages and their remedies, refer to Other Errors (P.518).

Encryption Key for Confidential Data
Setting an encryption key allows you to encrypt confidential information such as the
passcodes of the system administrator and mailboxes. This prevents interceptions and
unauthorized access to the information during transmission across networks.
Select [Keyboard], and then enter an encryption key of 4 to 12 digits using the keyboard on
the screen.
Important • If you change the existing encryption key, confidential information may not be able to be
restored from a backup.
Note • The factory default encryption key is "x-admin".
