* If the default value is “1”, change the “Pure Black and Gray” setting to “Off” on the Color Settings menu
of printer driver since no value smaller than 1 is provided.
When “Text, Graphic & Image” is selected for the “Apply to” setting on the printer driver setting menu,
photo areas whose colors are close to black may be treated as black because the larger the value is, the
wider the area to be printed only with K toner becomes. Therefore adjust the value carefully while
checking the copied image.
