The part numbers you gave are Mimaki's internal part numbers for the blank PCB itself and not the completed one that is populated with all the components. That said, if it have the right number of Head Connections (4-pairs) then you should be all set. There were two versions of the board, the older one laden with mercury, lead and other nasty things and the newer environmentally friendly version that meets RoHS standards. They are interchangeable in your printer though.
If you get stuck we have lots of quality used JV3 parts (as well as many new parts).
