2.20 SECURITY SETTINGS
2.20.1 SECURITY FUNCTION INSTALLATION
The machine contains the Security functions (Data Overwrite Security and HDD Encryption unit)
in the controller board.
If you are installing a new machine, it is recommended to activate the Data Overwrite Security and
HDD Encryption by selecting "Format All Data" from “System Settings” on the operation panel.

This method is recommended because there is no user data on the hard drive yet
(Address Book data, image data, etc.).
If the customer wishes to activate the Data Overwrite Security and HDD Encryption unit on a
machine that is already running, it is recommended to activate the unit by selecting "All Data" from
“System Settings” on the operation panel.

Selecting "All Data" will preserve the data that has already been saved to the hard drive.
(If "Format All Data" is selected, all user data saved to the hard drive up to that point will
be erased).
Immediately after encryption is enabled, the encryption setting process will take several minutes
to complete before you can begin using the machine.

If encryption is enabled after data has been stored on the disk, or of 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.
Make sure that the machine's main power is not turned off while the encryption process is in
progress.
If the machine's main power is turned off while the encryption process is in progress, the hard disk
will be damaged and all data on it will be unusable.
Print the encryption key 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 controller
board, hard disk and NVRAM must all be replaced at the same time.

"NVRAM" mentioned in here means the NVRAM on the Controller Board.

"NVRAM" or EEPROM on the BCU has nothing to do with this.
Please use the following procedure when the Data Overwrite Security and HDD Encryption are
reinstalled.
