2.7.1 SECURITY FUNCTION INSTALLATION
If the “Enhanced Security HDD Option Type M10” is installed at the same time as the main
machine’s installation, do not execute these settings described below.
• When the “Enhanced Security HDD Option Type M10” and security functions (Data
Overwrite Security and HDD Encryption functions) are activated in the same machine,
the function of the “Enhanced Security HDD Option” is not guaranteed.
The machine contains the security functions (Data Overwrite Security and HDD Encryption
functions) in the controller board (PCB24).
If you are installing a new machine, it is recommended to activate Data Overwrite Security and
HDD Encryption by selecting "Format All Data" in "Machine Data Encryption Settings".
("Settings" icon> [System Settings] > [Settings for Administrator] > [File Management] >
[Machine Data Encryption Settings])
• This method is recommended because there is no user data saved on the hard drive
yet such as Address Book, image data, etc.
If the customer wishes to activate the Data Overwrite Security and HDD Encryption functions on
a machine that is already running, it is recommended to activate these functions by selecting
"All Data" in "Machine Data Encryption Settings". ("Settings" icon> [System Settings] > [Settings
for Administrator] > [File Management] > [Machine Data Encryption Settings])
• If "All Data" is selected, all the data saved on the HDD will be preserved. If "Format All
Data" is selected, all the user data saved on the HDD will be erased.
After enabling encryption, the setting process takes several minutes to complete before the
machine can be used.
• If encryption is enabled after data has been stored on the HDD, or if the encryption key
is changed, this process can take up to three and a half hours or more.
The machine cannot be operated while data is being encrypted.
Once the encryption process begins, it cannot be stopped.
DO NOT turn off the power while the encryption process is in progress.
If the machine's main power is turned OFF while the encryption process is in progress, the HDD
will be damaged and all data on it will be unusable.
Print the encryption key or save to SD card and keep the encryption key (which is printed as a
paper sheet).
Keep the encryption key in a safe place. If the encryption key is lost and is needed, the
