Warning—Potential Damage: When replacing any of the following components:
• Control panel assembly
• Controller board assembly
Replace only one component at a time. Replace the required component and perform a POR before replacing a second
component listed above. If this procedure is not followed, the printer will be rendered inoperable. Never replace two
or more of the components listed above without a POR after installing each one or the printer will be rendered
inoperable.
