Please add the following procedures, which are required before/after replacing the NVRAM, to your
field service manual in the following section:
Replacement and Adjustments > Main Boards, HDD Units > IOB/BCU > Controller Board (GW),
NVRAM, Controller Board Fan > NVRAM
IMPORTANT
Make sure to update the System firmware to the version listed below or newer to enable
proper NVRAM data backup/restore functions using the SD card:
Firmware Copier Printer
System
1.13 or newer
(D0745773M or newer)
1.07 or newer
(M0445773G or newer)
With System firmware version 1.12 or older (copier) / 1.06 or older (printer), NVRAM
data could not be properly backed up or restored due to a bug.
Please contact your supervisor with the machine serial number information for the
following cases:
1. The machine is experiencing problems as a result of NVRAM data backup/restore
that had been performed using the System firmware version 1.12 or older (copier)
/ 1.06 or older (printer).
2. NVRAM requires replacement, but data cannot be backed up/restored due to a
defective NVRAM.
RCL will provide the factory default SP values to enable restoration of the SP values
unique to the machine you are servicing.
The Security & Encryption SD card must be replaced together with the NVRAM because the
SD Card and the NVRAM are associated at the factory.
