JPEG was selected for 
the file type but the file 
was created as a TIFF 
file.
Did you press the [BLACK & WHITE 
START] key to begin scanning?
When [JPEG] is selected for the file type and the image 
is scanned in Mono 2, the file will be created as a TIFF 
file. To create the file as a JPEG file, change the color 
mode to [Full Color] and then press the [COLOR 
START] key.
The image is too light 
or too dark.
(When using PC 
Scan.)
Is the threshold value suitable? 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.
