preferable to specify OFF for this item.

PURE BLACK TEXT: OFF
BLACK OVERPRINT
ON*, OFF
Specifies the printing method for when the printer prints black text over a color
background or graphics.
If ON is specified, the printer prints black text over a color background. If this
option is used with PURE BLACK TEXT, the printer prints all the background first,
and then prints the text over the color background using only the black (Bk) toner.
This alleviates the phenomenon in which the outlines of the printed black text are
rimmed with white.
Test
BLACK OVERPRINT: ON
If OFF is specified, black text is printed without being overlaid on a color
background. The printer first prints the color background with the text areas
"knocked out" (no color is printed in the text areas). The text is then printed in the
knocked out area, filling in the areas not printed in color. However, this may result
in the black text appearing lighter compared to when ON is specified or the
phenomenon in which the outlines of the printed black text are rimmed with white.
