Description/Action
This error code indicates a mismatch between the
RIP card assembly and the interconnect card
assembly.
Warning: In the event of replacement of any one of
the following components:
• RIP card assembly
• Interconnect card assembly
Only replace 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.
Warning: Never install and remove components
listed above as a method of troubleshooting
components. Once a component has been installed
in a machine, it cannot be used in another machine.
It must be returned to the manufacturer.
