* ERR DIFFUSION is displayed only when RESOLUTION is set to FINE.
Specifies the display pattern of subtle gradation (medium gradation) for color data
for each text part, graphics part such as diagrams and graphs, and image part
such as picture images.
RESOLUTION prints precisely so that the lines of text data appear clearly. This
setting is appropriate for printing data that contains text or thin lines.
GRADATION prints with a stable texture and color hue, and a smooth gradation
combined. This setting is appropriate for printing image data such as
photographic images, because it reduces a phenomenon of "Out-of-Register
Colors".
Although COLOR TONE prints precisely with the phenomenon of "Out-of-Register
Colors" reduced than GRADATION does, the stability of the texture is lower in
quality. This setting is appropriate for printing diagrams, graphs, etc.
Although HIGH RESOL. prints in higher resolution than RESOLUTION does, the
stability of the texture is lower in quality. This setting is appropriate for printing a
document so that the outlines of text, thin lines, or CAD appear clearly.
ERR DIFFUSION uses an error diffusion method that gives priority to printing fine
lines or text. This setting is appropriate for printing images with small text or very
fine lines.

Specifies whether to print gray color data with the black toner (Bk) only.
If ON is specified, the printer prints gray color data with the black toner (Bk) only.
You can prevent a phenomenon of "Out-of-Register Colors".
If OFF is specified, the printer prints the gray color of gray color data using the
four colors of CMYK. The ability to reproduce the tone of the dark parts is more
improved than when ON is specified.
