• Selectors 1 through 8: Change rate of the CCD scanning light intensity to judge to be
The light intensity of the CCD unit is changed widely immediately after the light source is
on, that influences scanning density. Therefore, the first scanning after the light source is
off and on is started after the change rate of the CCD light intensity is stabilized in the
definite range. These selectors set the change rate to start the scanning operation above. If
you want to start scanning immediately even if the image quality is not good, set the rate to
high.
Long / short time mode:
The selectors are divided between the long and short time modes depending on the
scanning resolution and black and white or color mode. The long time mode is selected in
color scanning at 600dpi or more, or in black and white scanning at 1200dpi. The short time
mode is selected in other scanning conditions than the above.
