2.12 Protecting Data in the HDD
When access to the machine by the Administrator of the machine through the Administrator Settings from 
the control panel is authenticated, the machine enables the operation for setting and changing the Encryption 
Key.
By setting the Encryption Key, the data stored in the HDD is encrypted, thereby protecting the data in the 
HDD. The Encryption Key entered is displayed as *.
Reference
-When an Encryption Key (encryption word) is set using HDD Encryption Setting, an Encryption Key with 
a key length of 128 bits is generated. The generated encryption key is used to encrypt or decrypt data 
through AES encryption algorithm.
2.12.1 Setting the Encryption Key (encryption word)
0For the procedure to call the Security Settings screen on the display, see steps 1 and 2 of page 2-10.
0Do not leave the machine with the setting screen of Administrator Settings left shown on the display. If 
it is absolutely necessary to leave the machine, be sure first to log off from the Administrator Settings.
0To prevent data from leaking as a result of reinstallation of the HDD on another machine, a unique value 
that varies from one machine to another must be set for the encryption key.
0Do not set any number that can easily be guessed from birthdays, employee identification numbers, 
and the like for the Encryption Key. Try to change the Encryption Key at regular intervals.
0Make sure that nobody but the Administrator of the machine comes to know the Encryption Key.
0If only the Encryption Key is to be set while the machine is being used without setting the Encryption 
Key, the Service Engineer must perform some setting procedures in advance. For details, contact your 
Service Representative.
0To change the Encryption Key, see page 2-56.
0Executing HDD Format erases data in the HDD. It is recommended that important data should be saved 
in a backup medium in advance. Execution of HDD Format will also reset the setting values of different 
functions to the default values. Set the Enhanced Security Mode to [ON] again. For the functions whose 
settings are reset to the default values, see page 2-10.
1Call the Security Settings screen on the display from the control panel.
