Warning—Potential Damage: When replacing the operator panel assembly or the system card assembly,
make sure to:
• Replace only one component at a time.
• Perform a POR every after each component is replaced.
If this procedure is not followed, then the printer will be rendered inoperable.
These components can be used as a method of troubleshooting as long as the machine is booted into diagnostic
