• The following shows the procedure for replacing the NVRAM on the BiCU with a new NVRAM.

  1. Make sure that you have the SMC report (factory settings). This report comes with the machine.
  2. Output the SMC data (“ALL”) using SP5-990-001/SP5-992-001.
  3. Turn off the main switch.
  4. Insert a blank SD card in the SD slot #2, and then turn on the main switch.
  5. Use SP5-824-001 to upload the NVRAM data from the BiCU
  6. Turn off the main power switch and unplug the power cord.
  7. Replace the NVRAM on the BCU with a new one.

    • Install a new NVRAM [A] so that the indentation [B] on the NVRAM corresponds with the mark on the BiCU. Incorrect installation of the NVRAM will damage both the BiCU and NVRAM.

  8. Plug in, and then turn on the main switch.

    • When the power is turned ON, SC195-00 appears. Continue with the following steps.

  9. Select the destination setting (SP5-131-001 - JPN: 0, NA: 1, EU/AA/TWN/CHN: 2).

    • After changing the EEPROM, some SPs do not have the correct values.
    • Because of this, steps 10 to 12 must be done.

  10. Set the machine serial number SP5-811-001, Area selection SP5-807-001, CPM set SP5-882-001.

    • For information on how to configure the above SPs, contact the supervisor in your branch office.

  11. Cycle the power off/on.
  12. Use SP5-801-002 “Memory Clear Engine”.
  13. Turn off the machine, and then turn it back on.
  14. From the SD card where you saved the NV-RAM data in step 5, download the NV-RAM data with SP5-825-001.
  15. Turn off the machine, and then remove the SD card from SD slot 2.
  16. Turn on the main power switch.
  17. Check the factory setting sheet and the SMC data printout from step 2, and set the user tool and SP settings so they are the same as before.
  18. Execute ACC (Copy and Printer).
