Encrypting Data to Prevent Data Leaks Caused by a Stolen or Disposed Machine | User Guide | IM 7000, IM 8000, IM 9000
Keep SD cards or USB flash memory devices out of reach of children. If a child accidentally
swallows an SD card or USB flash memory device, consult a doctor immediately.
You can encrypt data contained in the Address Book, authentication information, and stored documents to
prevent data leaks in case the hard disk is removed from the machine.
Once encryption is enabled, all data subsequently stored on the machine will be encrypted.
The encryption algorithm used in the machine is AES-256.
This function is only available for the standard hard disk. If your machine is equipped with the
Enhanced Security HDD Option, data on the hard disk is always encrypted. Therefore, this
function can only encrypt the machine's NVRAM data.
The machine cannot be operated while encrypting data, updating the encryption key, or canceling
encryption.
Do not turn off the power of the machine while encrypting data, updating the encryption key, or
canceling encryption. If you turn off the power, the hard disk may be damaged and all data may be
unusable.
If the encryption key update was not completed, the created encryption key will not be valid.
After completing this procedure on the machine's control panel, turn off the main power and restart
the machine to enable the new settings by turning it back on. Restarting can be slow when there is
data to be carried over to the hard disk.
The encryption process takes several hours. Once the encryption process starts, it cannot be
stopped.
The encryption key is required for data recovery or migration to another machine. Be sure to keep
the encryption key secure by printing it on a sheet or storing it in an SD card.
To transfer data from the machine to another machine, you must decrypt the encrypted data.
Contact your service representative for data migration.
If you specify both the Erase All Memory function and the encryption function, the Erase All
Memory function is performed first. Encryption starts after the Erase All Memory function has been
completed and the machine has been rebooted.
If you use the Erase All Memory function and the encryption function simultaneously, and select
overwrite 3 times for the Random Numbers overwriting method, the process will take up to 9 hours
and 8 minutes. Re-encrypting from an already encrypted state takes the same amount of time.
The Erase All Memory function also clears the machine's security settings, so that neither
machine nor user administration will be possible. Ensure that users do not save any data on the
machine after the Erase All Memory process is completed.
Rebooting will be faster if there is no data to carry over to the hard disk and if encryption is set to
[Format All Data], even if all data on the hard disk is formatted. Before you perform encryption, we
recommend you back up important data such as the Address Book and all data stored in
Document Server.
When disposing of a machine, completely erase the memory. For details about erasing all the
memory, see the section below:
