Clearing the NVRAM RICOH MP161

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 1.
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 1.
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.

Error 950.01 NVRAM Missmatch


Have you recently tried adding to or replacing the internal rem modules? If not they could have developed a fault. Try removing the and rebooting the printer see if that resolves the issue. I have also see this happen with a faulty daughter board which the ram plugs in to on a hp printer

reset imaging unit life


Usually it should do it automatically once you have replaced to a New image unit.
If you are still getting that error then you will have to change the engine control board.
You can first try this tip reset the nvram from the service diag mode some errors get stuck in the NVRAM and won't get off until a reset is done in the NVRAM. Hope this helps.
