Code: 950.00, 950.29
Description: NVRAM mismatch
Remedy: 1 Interface card If the interface card been recently replaced, go to step 3. If the card has not been replaced go to step 2. 2 Operator panel board If the operator panel board has been recently replaced, go to step 4. If the operator panel board has not been replaced, contact your next level of support. 3 Interface card Replace the current interface card assembly with the original interface card assembly. See “Interface card assembly removal”. If the error remains, go to step 5. 4 Operator panel board Replace the current operator panel board with the original operator panel board. See “Operator panel right cover assembly removal”. If the error persists, go to step 6. 5 Interface card Replace the original interface card assembly with a new and not previously installed interface card assembly. If the error remains, contact your next level of support. 6 Operator panel Replace the original operator panel board with a new and not previously installed interface card assembly. If the error remains, contact your next level of support.

Description:
Remedy: Replace the system board. See “System board and inner shield removal —models X644e/X646e”. Warning: When replacing any one of the following components: • Operator panel right cover assembly • System board assembly • Interface 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 printer, it cannot be used in another printer. It must be returned to the manufacturer.
