950.30 through 950.60 EPROM mismatch failure
Warning: When replacing any one of the following components:
• Flatbed interconnect card (ICC)
• 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.
Note: Before proceeding with this service check, make sure you have the correct system board installed in the
printer. The system board has a label with an board ID and barcode. Use the first eight numbers to identify the
board with the part number in the table below:
This error code indicates a mismatch between the system board and the interface card.

FRU Action
1 Interface card assembly If the interface card assembly has been recently replaced, go to step
3. If the interface card assembly has not been recently replaced,
contact the next level of support.
2
System board If the system board has been recently replaced, go to step 4. If the
system board has not been replaced, contact the next level of
support.
3
Interface card assembly Replace the current interface card assembly with the original
interface card assembly. See “Interface card assembly removal”
on page 4-107. If the error remains, go to step 5.
4
System board Replace the current system board with the original system board.
See “System board and inner shield removal —models X644e/
X646e” on page 4-131.
If the error remains, go to step 6.
5
Interface card assembly Replace the original interface card assembly with a new and not
previously installed interface card assembly. If the problem remains,
contact the next level of support.
