More approximate —this option removes a wider range of co lors based on the pure color selected 
in the list or defined in the custom fields.
This option is only available when scanning in gr ayscale or black and white. The example below shows 
the original text with a red watermark and the resulting image with the color removed.
Perform Color Correction
Apply color correction to the image so the displayed  colors approximate the original item colors. Select 
this option to use the scanner’s default Gamma tabl e which has been calibrated to produce the best 
quality color results for your scanner. When this opti on is not selected, the resulting scans will be dark 
and the brightness, contrast, and gamma options will  require a greater amount of adjustment to affect 
the overall lightness of the image.
Advanced Panel Options
The options in this panel may also appear in the  Main panel, but with additional settings for you to 
fine-tune the feature you've selected. Select the  Advanced source configuration mode to show this 
panel.
Despeckle
This option removes speckles from the background . Speckles are small spots on an image that the 
scanner interpreted as a valid part of the document. For example, an irregularity in the paper, a small 
wrinkle, or holes where a staple was removed may  show up as speckles in the scanned image. The 
Despeckle  option identifies these spots and removes them.  This option is only available when scanning 
in black and white. 
Radius —this is the size of the area that is evaluated for stray dots.

Number
—this is the maximum number of  dots within the radius that should be considered a speckle. 
If this number of dots are in the circle, the dots will not be considered a speckle and remain in the 
image. If there are less than this number of dots in the circle, the dots are considered a speckle and 
removed from the image.
For example, if the radius is 3 and the number is 5,  then the document is evaluated in sections of 3x3 
pixels and if there are more than 5 stray dots wi thin a 3x3 area, they are not considered a speckle.
Filter
Use the Filter option to increase or decrease the sharpness in the scanned image. Click the drop down 
menu and select an option from the list. 
Moiré Reduction
Moiré patterns are wavy or rippled lines that may  appear in the scanned images of newspapers and 
magazines, and sometimes scanned images of phot os, line drawings, and color scans of textured 
paper. Select the  Moiré reduction option to have the driver attempt  to find and remove moiré patterns 
from the image. Please note that when Moiré reduction is enabled the scanner may scan slower as the 
image is checked for moiré patterns. This op tion is only available when scanning in Color or Gray .
Moiré radius —you can set the size of the area to be evaluated in the Moiré radius field. Adjusting the 
radius will produce different results for the variou s types of items that can be scanned. With this 
feature, you may have to test scan a few times, adjusting the Moiré radius as needed, until you obtain 
the best results for the type of paper in your scan jo b. Note that the higher the number is in the Moiré 
radius field, the longer it will take the driver to evaluate the image.

White Level
With this option you can set what the scanner should interpret as “white” in the final image, even 
though the page being scanned may have a shaded 
or off-white background. You may want to adjust 
this option to have the image automatically corrected when you are scanning irregular paper, such as 
thick or thin paper, that may cause the white page  in the final image to appear shaded with a pale 
grey. 
For the best automatic results you can simply select the type of paper you are scanning from the list.  
Alternatively, you can input a number in the Custom  value field. The value you set in this field can be 
from 128 to 255. If you set the custom value to 128 you are telling the scanner that all pixels that are 
grey level 128 or higher (lighter) should be changed  to white in the final image. If you set the custom 
value to 255, you are telling the scanner that only pure white is white and anything lower than 255 
should remain unchanged in the final image.
Black Level
With this option you can set what the scanner should  interpret as “black” in the final image. If you are 
scanning items that have notes written with a pencil , you may want to raise the black level to have the 
pencil notes appear black in the image.  You can set a value for black from 0 to 127.  If you set this 
value to 127, you are telling the scanner that all pixels that are grey level 127 or lower (darker) should 
appear as black in the final image.

Driver Configuration
Use the 
Driver configuration section to configure the add-on modu les, select interface options, and 
view the scanner hardware properties. When the  Advanced configuration mode is selected, a scanner 
panel option will be available for you to change any hardware settings that may be available for your 
scanner.
Disabled Options in this Section
Some options in the interface may be grayed out an d cannot be selected. Grayed out options are either 
not appropriate for the current scanner, the software  needed to enable the feature is not installed, 
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.
Module Configuration
When image processing modules are installed they will appear in the list on the  Configure tab. Use this 
tab to enable the modules yo u want to use when scanning. 
There are some features in the scanner interface th at are disabled until a module is installed that 
contains those options. When the mo dule is installed, the features will enable in the scanner interface 
for you to use them. 
Reordering the Modules
Select a module in the list and click the up or down  arrow to change the order of the module in the list. 
Changing the order of the modules changes the orde r in which the image processing options are used. 
For example, if there are two modules installed and  both modules include an automatic image rotation 
option, the first module's rotate option is used and  the rotate setting in the second module is ignored 
so that the image is not rotated twice.

Driver Settings
The options in this panel are for configuring how the 
scanner interface will behave in some scenarios. 
Only advanced users should modify any of the options  in this section. Options that are not available for 
your scanner will be grayed out and disabled.
General
• Lock settings —this option prevents the user from maki ng changes to the options in the scanner 
interface. When the interface opens, only the scanning Presets will be available for a user to select 
and use for scanning. 
• Default preset —select the preset you want to have be  the default displayed options in the 
scanner interface each time it opens.
TWAIN Driver

•
Fo rc e  U I - l e s s —select this option to preven t this scanner interface from opening when you initiate 
a scan in the scanning application. This option will only work if  your scanning application supports 
UI-less scanning. You may also need to select Auto  close on transfer complete for this option to 
work.
• Preset overrides capabilities —some scanning applications have the option to adjust the scan 
settings and scan without opening this scanner inte rface. The next time this interface opens, the 
last used settings will match the application settings  that were used to scan. Select this option to 
have the settings reset to the last ones  used when this interface was open.
• Enable user compression —this option is enabled only if the scanner and the software allow 
manual adjustment of the image compression. 
• Remember compression —when a compression option is availa ble for user adjustment, it cannot 
be saved as part of a preset. Select this  option to have the compression setting saved.

•Use default WIA UI —select this option to display the Mi crosoft WIA interface instead of the 
TWAIN interface in WIA 2.0 applications.
• Emulate WIA 1.0 —select this option to display the TW AIN interface for WIA 1.0 compatible 
applications. When this option is selected, WIA 2.0 applications will use the Microsoft WIA
