Toshiba e-STUDIO500P manual Through 950.60 Eprom mismatch failure

950.30 through 950.60 EPROM mismatch failure

Warning: When replacing any one of the following components:

•Operator panel assembly (or upper front cover)

•System board 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 printer, it can not 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 interconnect card.

	FRU	Action
1	Interconnect card assembly	If the interconnect card assembly has been recently replaced, go to
		step 3. If the interconnect 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	Interconnect card assembly	Replace the current interconnect card assembly with the original
		interconnect card assembly. “Interconnect card assembly
		removal” on page 4-53.
		If the error remains, go to step 5.
