Designjet T520 Blue Screen Error B87E43AA

Blue Screen Error B87E43AA. 

Is this the formatter board ? Bundle board ?

HP quoted a price that is more than I paid for it to repair it on site.

I have been told by HP 2nd level support that any time you see a blue screen like this it is the main board that needs to be replaced, there is really only one primary board in this unit. Replacement is fairly straightforward but does require some disassembly of printer.

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.

Restart printer without any network/USB cable and check if you still have same error. If Yes, then you need to replace the main PCA board. 

Please check with nearest authorized service providers to replace parts for low price.


Part numbers for MPCA:

A series.

CQ890-67097 AXL MPCA and Bundle Pro kit

B&C series. 
CQ893-67032 Formatter (main logic) PC board assembly - For model C T520 printersT520 B&C series

Hope it will be useful.
