GReyscale Printing on Roland v540

[Rainbow Printing]

I am trying to print small labels on my Roland v540. I'm having trouble with the print quality, my label is just black text (100% Black) but my printer keeps printing the label in CMYK RICH Black, which is making some of the letters (ie e, a, s) fill in with more ink then needed.
Any thoughts or comments?
thanks, Rainbow
