Warning! Observe all ESD precautions while handling electronic parts.
Warning! When replacing any one of the NVRAM components:
•
Only replace ONE component at a time – NEVER replace two or more at once.
•
Perform a POR before replacing the second component. If this procedure is not followed,
the printer will be rendered inoperable.
•
These components mirror the critical NVRAM settings for the printer. If you have not already
done so, complete the online course Mirrored NVRAM from Lexmark's online learning site.
Warning! If you must use one the components listed above as a method of troubleshooting, boot the
printer into Diagnostic mode only. This will prevent the NVRAM from copying to the new component. If
the printer is allowed to boot normally, however, the NVRAM will copy to the new component and it
cannot be used in another printer. It must be returned to the manufacturer.
