1. Disconnect and remove the BCU (x2,x2,x2)

  2. If you are replacing the BCU, remove the NVRAM [A], and then install it on the new BCU.

    • Pay attention to the direction the circular notch is pointing when you install it. If the NVRAM is installed incorrectly, the machine will display “Please Wait” and then freeze and not boot.

  3. Turn the machine on.
  4. Enter the SP mode.
  5. Do SP5811-004 and enter the serial number of the main machine. If you fail to enter the correct number, the machine will issue SC995-01.
  6. Do SP5131-001 and select paper size type (0: Japan, 1: NA, 3: EU).
  7. Do SP5807-001, and then select your area. Failure to do this will cause the machine to return SC995-04.
