DF: Density Adjustment 688
DF: Density
Adjustment
Adjusts the brightness for scanning using the ARDF.
[83
∼ 100 / 100 / 1 %/step]
The density when scanning from the DF exposure glass
tends to be higher than the density from the main
exposure glass. SP4-688 adjusts the density on the DF
exposure glass.
