Nozzle checks don't print green. Green is made from Yellow and Cyan. If your nozzle check shows both yellow and cyan then something else is wrong, likely in your file or other setup. The nozzle checks CMYK colors
A more comprehensive way to check nozzle health is to print a "purge file" simply color bars of the primary colors CMYK.
