PROBLEMS RELATED TO ONE-TOUCH INDIVIDUAL
KEYS / GROUP KEYS
The image is too light
or too dark.
(When using PC
Scan.)
Is the threshold value suitable? Check the "B/W Threshold" setting.
When scanning from the TWAIN driver with [Mono 2
gradation] selected from the [Color Mode] of the
"Custom Settings" window, check the "B/W Threshold"
setting. A large threshold value makes the image darker
and a small threshold value makes the image brighter.
To adjust the "B/W Threshold" automatically, click the
[Auto Threshold] button on the [Image] tab of the
"Custom Settings" window.
Are the brightness and contrast settings
suitable?
When the brightness and contrast settings are not
suitable (for example, the scanned image is too bright),
click the [Auto Brightness / Contrast Adjustment] button
on the [Color] tab of the "Custom Settings" window. You
can also click the [Brightness / Contrast] button to set
the brightness and contrast while viewing the scanned
image.
