remove it from the final file. Typically you might use this option when scanning a stack of two-sided 
pages which have a number of blank sides.

Blank threshold—you can use the Threshold slider to fine tune the sensitivity of the blank image 
detection. The results will depend on the scan settings and the types of documents being scanned.

Disabled Options in this Section

or 
the feature is dependent on another setting in the scanner's interface. Hover the mouse cursor over a 
grayed out feature to see information about why the feature is unavailable.

User’s Guide175 Brightness
 works in conjunction with Contrast for image enhancement. When you are adjusting the 
brightness level to improve the scanned image quality, try adjusting the contrast level as well. The 
contrast level is the range between the lightest and darkest parts of the image. For example, if you 
scanned a document with notes written in pencil, you may have to decrease the brightness level to get 
the handwritten notes to appear in the scanned image. However,...

User’s Guide 176 Choosing contrast values
While Brightness adds the same amount of gray or white to all pixels in the image, Contrast adjusts the 
pixels based on the pixel color level. For instance, increasing the contrast level will add white to light 
colored pixels and gray to dark pixels to make the difference between color levels in the image crisper. 
Decreasing the contrast level will have the opposite affect, where light colored pixels are modified with 
gray and dark...

User’s Guide177 Black background scanners:
Some scanners have a black background plate. A black background results in more precise cropping 
results and skew detection. However, when scanning thin paper, such as carbon copy paper or ruled 
writing paper, which are less than 18lb paper weight, the background may “bleed” through into the 
final image and make the image darker than it should be. In that case, try adjusting the brightness 
level between 40% and 60%, then adjust the...

User’s Guide 178 Technical note:
Most monitors have a gamma setting that is user adjustable. When viewing scanned images on-screen, 
versus printing the image, the gamma setting of the monitor may affect how light or dark the scanned 
image looks when compared to the original. If the scanned image is too different from the original 
image, or if adjusting the scanned gamma level does not modify the image how you want, try 
adjusting the monitor's gamma level. Refer to the...

User’s Guide 180 Error diffusion, Bayer, and Halftone pattern
Error diffusion
, Bayer, and Halftone patterns are the intentional application of noise (dithering) in the 
image to help alleviate banding when scanning in binary (black and white) mode. For example, if you 
scan a color photo in black and white, the image file will have large blocks of black and white and the 
image barely recognizable. Dithering the image creates a black and white image that is recognizable.
