Starting the Data Encryption and Changing Settings
When you change the Data Encryption setting or the encryption key, you must restart the
machine. When the machine reboots, the machine initializes part of the disk area. The
previous data is not secured.
The disk area stores the following data.
- Spooled print data
- Print data including Secure Print and Sample Set
- Forms for the Form Overlay feature
- Folder and job flow sheet settings (folder name, passcode, etc.)
- Files in folders
- Address book data
Note • Be sure to save all necessary settings and files before using data encryption or changing any settings.
• Make sure that the hard disk and encryption settings match. Otherwise, an error will occur. For
information on error messages and their remedies, refer to "Other Errors" (P.682).
• The following procedure is recommended for changing the encryption settings while a large amount
of data (100 jobs or more) is stored in a folder, and [Number of Overwrites] is set to [1 Overwrite] or [3
Overwrites] under [Overwrite Hard Disk].
1. Select [Tools] > [Setup] > [Create Folder] to display the [Create Folder] screen.
2. Select the folder, then select [Delete Folder].
3. Select [Close].
4. Press the <Machine Status> button, and confirm that [Standby] in [Overwrite Hard Disk] is
displayed.

For information on how to enter the System Administration mode, refer to "System Settings
