When scan density is adjusted manually away from
the Normal setting, the threshold value for binary
picture processing changes for each step from the
value specified by Scanner Switch 02, by the
amount programmed here.
For example, with the default setting (14), the
threshold value changes as follows.
+3 (Darkest) : 71 (= 85 – 14)
+2 :
+1 :
0 (Normal) : 113 (Scanner Switch 02 setting)
-1 :
-2 :
-3 (Lightest) :
For smaller steps, input a lower value.
This setting determines the threshold value for
binary picture processing in Text mode (when the
scan density setting is at the center).
The value can be between 01 and FF. For a darker
threshold, input a lower value.
Default setting: 71(H) = 113(D)
This setting determines the threshold value for
binary picture processing in monotone background
special original 1 mode (when the scan density
setting is at the center).
The value can be between 01 and FF. For a darker
threshold, input a lower value.
Default setting: A4(H) = 164(D)
