SP4 Mode Number Function and [Setting]
4904* 3* Density Setting for Low
Density Original Mode
Selects the density γ factor for the low-density
original mode.
[0~1 / 0 / 1]
0: Selects γ normal density.
1: Digitizes to near binary image.
Use to achieve better balance between text and
images, correct shadows that appear around
text in handwritten documents, to enhance
documents written in pencil, or to achieve stark
contrast when copying blueprints, building plans,
etc.
4* Density Setting for Copied
Original Mode
Setting same as above.
[0~1 / 0 /1 step]
7* Error Diffusion Pattern Adjusts the threshold level for error diffusion
processing in the text/photo mode.
[0~2 / 0 / 1 step]
0: No pattern (matrix) used.
1: Matrix 1 used.
2 Matrix 2 used.
Select zero for daily use. Select 1 or 2 to
improve the texture.
12* Binary Threshold Level Selects the threshold value for binary digitization
of the copied image.
Image data equal to or greater than the value is
processed as black; image data less than the
value is processed as white.
[0~255 / 128 / 1 step]
This feature is not used for copy applications.
Other applications set for binary digital
processing will use the SP as the default setting.
18* Binary Dither Pattern Selects the dithering threshold value for the
pattern to be used in the photo mode during
binary processing.
[0~3 / 0 / 1 step]
0: 106 lines (8 x 8 matrix)
1: 141 lines (6 x 8 matrix)
2: 212 lines (8 x 8 matrix)
3: 268 lines (8 x 8 matrix)
