When Installing The New Bcu; Replacing The Nvram (Eeprom) On The Bcu - Ricoh MP C3004 Field Service Manual

When installing the new BCU

Remove the NVRAM (EEPROM) [A] from the old BCU. Then install it on the new BCU after you replace
the BCU.
Replace the NVRAM (page 687 "Replacing the NVRAM (EEPROM) on the BCU") if the NVRAM on
the old BCU is defective.
• Make sure you print out the SMC reports ("SP Mode Data" and "Logging Data") before you
replace the NVRAM (EEPROM).
• Keep NVRAMs (EEPROM) away from any objects that can cause static electricity. Static electricity
can damage NVRAM data.
• Make sure the serial number is input in the machine for the NVRAM data with SP5-811-004, if not,
SC995-001 occurs

Replacing the NVRAM (EEPROM) on the BCU

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.
Make sure to shut down and reboot the machine once before printing/exporting the SMC.
Otherwise, the latest settings may not be collected when the SMC is printed/exported.
3. Turn OFF the main power switch.
4. Insert a blank SD card in the SD slot #2, and then turn ON the main power switch.
5. Use SP5-824-001 to upload the NVRAM data from the BCU.
6. Turn off the main power switch and unplug the power cord.
7. Replace the NVRAM on the BCU with a new one.
