When Installing The New Controller Board - Ricoh MP C6502SP Field Service Manual

When installing the New Controller Board

There are two NVRAMs ([A] and [B]) on the controller board. The two NVRAMs are one set. NVRAM
[A] is labeled "2M-1", and NVRAM [B] is labeled "2M-2".
When replacing the controller board, remove the NVRAMs from the old controller board. Then install
them at the same position on the new controller board. If this is not done, SC195-00 occurs.
• Install NVRAM (2M-1) in the socket that has "FRAM-1" [C] printed next to it on the controller
board. Install so that the indentation [E] on NVRAM (2M-1) is facing the direction of the arrow [G]
that is printed on the controller board.
• Install NVRAM (2M-2) in the socket that has "FRAM-2" [D] printed next to it on the controller
board. Install so that the indentation [F] on NVRAM (2M-2) is facing the direction of the arrow [H]
that is printed on the controller board.
• Note that if you install incorrectly, both the controller board and NVRAMs will be damaged.
• When replacing the controller board, first, check which ESA applications have been installed. After
replacing the controller board, re-install the ESA applications by following the installation
instructions for each application.
