Diagnostic information2-33 7500-XXX 950.30 through 950.60 Service NVRAM mismatchEPROM mismatch failure 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: • Operator panel assembly (universal) • Operator panel controller card assembly • 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.
