SP4 Mode Number Function and [Setting]
4904* 9* Gray Adj.: Text/Photo (Edge
Det.) 65-154% Adjusts the setting for edge detection during
grayscale processing of originals scanned with
the Custom Setting of the Text/Photo mode at
65%-154% magnification. At defined edges error
diffusion executes on text to create sharp lines to
better define text characters, but in other areas,
error diffusion executes grayscale processing for
photographs. Select a lower setting for better
reproduction of photographs and a higher setting
for sharper text. [0~15 /
8 / 1]
0: Decreasing the setting (approaching “0”)
improves the appearance of photographs, but
can cause text and thin lines to drop out.
15: Increasing the setting (approaching “15”)
sharpens text and thin lines, but can also
cause grayscale areas to degrade.
