  2. Log in as the machine administrator from the operation panel.
  3. Select [Security Options], and then press the [OK] key.

  4. Select [Machine Data Encryption], and then press the [OK] key.

  5. Make sure that [Encrypt] is selected, and then press the [OK] key.

  6. When the optional hard disk is installed, select the data to be carried over to the hard disk and not be reset, and then press the [OK] key.
    To carry all of the data over to the HDD, select [All Data].
    To carry over only the machine settings data, select [File System Data Only].
    To reset all of the data, select [Format All Data].

  7. Select how to back up the encryption key.

    If you have selected [SD Card], insert an SD card into the upper media slot on the back of the machine and press the [OK] key to back up the machine's data encryption key.

    If you have selected [PrtOnPpr], press the [Print] key. Print out the machine's data encryption key, and then press the [Exit] key.

  8. Press [Exit].
  9. Log out.
  10. Power cycle the machine.
