The hard disk on this machine stores registered information for the Address Book and password information for the Mail Box/Address Book, in addition to storing data using the Mail Box and Fax functions. Therefore, it is necessary to manage the data in the hard disk with strong security measures.

With the machine equipped with functions such as data encryption and data erase, you can manage the data and prevent information leakage to retain security and confidentiality.

The machine separates and stores the job data when copying, sending, receiving, and printing into management information and actual data. The management information is automatically erased when the job is complete, but the actual data is stored in the hard disk.

With this function, you can completely erase all of the actual data in the hard disk of the machine by overwriting the 0 data or random data. This is effective in preventing data leakage when replacing or disposing the hard disk. For more information, see "Completely Erasing Unnecessary Data from the Hard Disk."

You can erase (initialize) data stored in the machine such as stored files, registered information of the Address Book, and job history. (See "Initializing All Data/Settings.")

For information on the optional products required to use this function, see "Optional Products Required for Each Function."

You can encrypt data stored in the hard disk, such as stored files in the Mail Box, registered information in the Address Book, job data, and password information, preventing the leakage of confidential information from the hard disk. For more information, see the manual for the HDD Data Encryption & Mirroring Kit.

You can encrypt the password and certificate information managed in the hard disk or SRAM using the TPM Settings mode. (See "TPM Settings.")
