I don't recommend black only with that or any inexpensive printer.
Sometimes you'll get lucky, but usually they band and look bad.

Additionally, I don't like the tone of most of the black inks.

Maybe they sent a version of PKN.  If you ordered the neutral inks as a set,
that set probably included the PKN instead of the PK, which would be shipped
with the warm set.
