2.23 SECURITY SETTING
2.23.1 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 that you activate Data Overwrite Security
and HDD Encryption by selecting the following on the operation panel.

MP 501/601: [User Tools] -> [Machine Features] -> [System Settings] -> [Administrator Tools]
-> [Machine Data Encryption Settings] -> [Encrypt] -> [All Data]

SP 5300/5310: [Security Options] -> [Machine Data Encryption] -> [Encrypt] -> [Carry Over All
Data]

This method is recommended because there is no user data on the HDD 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 that you activate the unit by selecting the
following on the operation panel.

MP 501/601: [User Tools] -> [Machine Features] -> [System Settings] -> [Administrator Tools]
-> [Machine Data Encryption Settings] -> [Encrypt] -> [All Data]

SP 5300/5310: [Security Options] -> [Machine Data Encryption] -> [Encrypt] -> [Carry Over All
Data]

Selecting the setting above will preserve the data that has already been saved to the
HDD. (If "Format All Data" is selected, all user data saved to the HDD 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 HDD, 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 HDD
will be damaged and all data on it will be unusable.
