Security Kit Functions

The security kit enables overwriting and encryption.
NOTE:
If you install the security kit, Running security function... appears when the machine starts up and it
may take a while.
Overwriting
Multi-functional products (MFPs) temporarily store the data of scanned originals and print jobs, as well as other
data stored by users, in the hard disk, and the data is output from the hard disk for printing. As the data storage
area used for such data remains in the hard disk as is until it is overwritten by other data, the data stored here
remains restorable using special tools for undesirable use.
The security kit deletes and overwrites (hereinafter collectively referred to as overwrite(s)) the unnecessary data
storage area used for the output data or deleted data to ensure that data cannot be restored.
Overwriting is performed automatically, without user intervention.
CAUTION:
When you cancel a job, the machine immediately starts overwriting the data that has been already
stored in the hard disk.
Overwrite Methods
There are two overwrite methods, which can be switched at any time.
Once Overwrite Method
Overwrite a target storage area of the hard disk (for overwriting) or entire hard disk (for system initialization) with
zeroes to disable data restoration.
3-time Overwrite (DoD) Method (default)
This overwrite method complies with U.S. Department of Defense (DoD) standards, and overwrites unneeded
data areas of the hard disk (in the case of overwriting) or all areas (in the case of system initialization) with
specific characters, their complements, and random characters to prevent data restoration. Data restoration is
not possible even when sophisticated restoration techniques are used, and a higher level of security than Once
Overwrite is obtained.
This method may take more time than Once Overwrite method to process a larger amount of data.
Encryption
MFPs store the data of scanned originals and other data stored by users in the hard disk. It means the data could
be possibly leaked or tampered with if the hard disk is stolen.
The security kit encrypts data before storing it in the hard disk. It guarantees higher security because no data
cannot be decoded by ordinary output or operations.
Encryption is automatically performed and no special procedure is required.
CAUTION:
Encryption helps enhance security. However, the data stored in the Document Box can be decoded
by ordinary operations. Do not store any strictly confidential data in the Document Box.
