1.2 Security Functions
Setting the Enhanced Security Mode to [ON] will validate the security function of this machine. For details of
the settings of different security functions to be changed by turning [ON] the Enhanced Security Mode, see
"Enhancing the Security Function" on page 2-9 .
Setting the Enhanced Security Mode to [ON] will enhance the authentication function. Access control is then
provided through password authentication for any access to the Administrator Settings, User Authentication
mode, Account Track mode, User Box, a User Box data file, and a Secure Print Document file. Access is
thereby granted only to the authenticated user.
A password that can be set must meet the requirements of the Password Rules. The machine does not ac-
cept setting of an easily decipherable password. For details of the Password Rules, see
"Password Rules"
on page 1-8 .
If a wrong password is entered, during password authentication, a predetermined number of times (once to
three times) set by the Administrator of the machine or more, the machine determines that it is unauthorized
access through Prohibited Functions When Authentication Error, prohibiting any further entry of the pass-
word. By prohibiting the password entry operation, the machine prevents unauthorized use or removal of da-
ta, thereby ensuring secured used of the machine.
To cancel the password entry operation prohibited condition, the Administrator must perform the Release
Setting. When the Administrator performs the Release Setting for the operation prohibited condition, a sound
operation control in utmost security is achieved under the control of the Administrator.
Setting the HDD Lock Password provides the following security function. That is, even if the HDD is illegally
replaced with another, the HDD authentication function prohibits access to the HDD, when the HDD Lock
Password is yet to be set or there is a mismatch in the passwords. In addition, should the HDD be removed
unawares, the HDD Lock Password locks the HDD protecting data contained in the HDD. Furthermore, by
mounting the optional Security Kit SC-503 and setting the Encryption Key, the data stored in the HDD is en-
crypted, thereby protecting the data in the HDD. Note, however, that the HDD Lock Password and Encryption
Key do not prevent the HDD from being physically removed. Make sure of a good operation control.
When the machine is to be discarded, or use of a leased machine is terminated at the end of the leasing con-
tract, the Overwrite All Data function overwrites and erases all data stored in all spaces of the HDD. The func-
tion also resets all passwords saved in the NVRAM to factory settings, preventing leak of data. For details of
items to be cleared by Overwrite All Data function, see
"Types of Data Cleared by Overwrite All Data
Function" on page 1-10 .
