This function is only available for the standard hard disk. If your machine is equipped with the Enhanced Security HDD Option, data on the hard disk is always encrypted. Therefore, this function can only encrypt the machine's NVRAM data.
Prevent information leakage by encrypting the Address Book, authentication information, and stored documents while the data is written.
When data encryption settings are enabled, an encryption key is generated and used to restore the data. This key can be changed at any time.
Data that is encrypted
This function encrypts data that is stored in the machine's NVRAM (memory that remains even after the machine is turned off) and on the hard disk.
The following data is encrypted:
Address Book data
User authentication information
Data stored in Document Server
Temporary stored documents
Logs
Network I/F setting information
System settings information
If the machine needs to be replaced, the existing data can be transferred to a new machine, even if the data is encrypted. To transfer data, contact your service representative.
You can back up the machine's data encryption key to an SD card. For details about how to use SD cards, see "Inserting/Removing a Memory Storage Device", Getting Started.
Time required for encryption
When setting up encryption, specify whether to start encryption after deleting data (initialize) or encrypt existing data and retain it. If data is retained, it may take some time to encrypt it.

Notes for enabling encryption settings
If you use Embedded Software Architecture application or App2Me, 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.
