Clearing the NVRAM
When replacing the controller board for a model in which the HDD encryption unit has been
installed and a customer has lost the encryption key, clearing the NVRAM is required to
recover the HDD encryption unit.
1. Prepare an SD card which is initialized.
2. Make the "restore_key" folder in the SD card.
3. Make an "nvram_key.txt" file in the "restore_key" folder in the SD card.
4. Input "nvclear" into the "nvram_key.txt" file.
5. Turn on the main power switch.
6. Confirm that the prompt on the LCD tells you to install the SD card (storing the
encryption key) in the machine.
7. Turn off the main power switch.
8. Insert the SD card that contains “nvclear” into slot 2.
9. Turn on the main power switch, and the machine automatically restores the encryption
key in the flash memory on the controller board.
10. Turn off the main power switch after the machine has returned to normal status.
11. Remove the SD card from slot 2.
12. Turn on the main power switch.
13. Initialize the NVRAM (SP5801-001) and HDD unit (SP5832-001) with SP mode.
14. The user must enable the HDD encryption unit with a user tool.
2.22.10 PICTBRIDGE
Unplug the main machine power cord before you do the following procedure.
You must install the PictBridge option in SD Card slot 1. However, the Postscript
option and the data overwrite security unit option are also installed in SD Card slot
1. You must do the SD Card Appli move procedure first if you have the postscript
or data overwrite security unit option installed and you want to install the
PictBridge unit.
