Encrypting Data on the Hard Disk

CAUTION


  • Keep SD cards or USB flash memory devices out of reach of children. If a child accidentally swallows an SD card or USB flash memory device, consult a doctor immediately.

Important

  • 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

Note

  • 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.

All Data:

Both the data to be kept and not to be kept when [File System Data Only] is specified

None

Approx. 6 hours and 30 minutes

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.
