Instructions for General Users

(for Both General Users and Administrators)
Security Kit Functions
The security kit enables overwriting and encryption.
Overwriting
The printer temporarily stores print jobs as data in the hard disk, and
prints from that data. Users can also store various types of data in the
hard disk. 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 unneeded 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.
Note When you cancel a job, the printer 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 Method (default)
Overwrite the same target storage area of the hard disk as mentioned
above with a random pattern twice and then with zeroes to prevent
data restoration. This method with its higher degree of security makes
data restoration much more difficult than the Once Overwrite method
even by a sophisticated restoration tool.
This method may take more time than Once Overwrite method to
process a larger amount of data.
Encryption
The printer stores Custom Box and Job Box data 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, data stored
in a Custom Box or Job Box can be decoded by the normal printing
operation. Never store confidential data in a Custom Box or Job Box.
