Dx2 head rank question


Hi I have just purchased a dx2 printhead.

The number on the side of the head in dull black writting is 3A1K030
but the Roland SC500 has six numbers. Also on top of the head there is a sticker with O2IJL1 but that doesn't help me either, can someone help me with this please.

i can't specifically help you but i do know that epson techs have a little program that converts those numbers. those same epson techs will admit that the rank numbers have almost no effect on print quality.
