User’s Guide 122–AutoCrop to original—Select this option to let the software automatically determine the size of the 
item being scanned.
–Straighten image—Select this option to have the software automatically determine if a page is skewed, 
then straighten its image. If the page is scanned at too great an angle, the image may not straighten 
correctly. In that case, re-scan the page.
–Auto detect color—Determines if a document contains color or not and produces the appropriate 
scanned image. Typically, Auto Color Detect is used when you have a stack of pages to scan, some color 
and others not. Instead of you having to change the scan settings from Color to Black&White and back 
again, the scanner can choose the correct settings automatically.
–Skip blank originals—Recognizes when a page is blank and removes its image. For instance, if you are 
scanning a stack of pages that includes a blank page, its image will not be included with the other images 
from the stack.
–Rotate image—Select an option in this list to have the final image rotated when scanning is complete. 
Automatic recognizes text on the page and rotates the image 90, 180, or 270 degrees so the text is right 
side up.
–Perform edge cleanup—Select this option to have the software remove any thin lines that may be 
around the edges in the scanned image. Edge Cleanup only applies if AutoCrop and AutoDeskew are 
selected so the software can determine where the edges are located. Therefore, selecting Edge Cleanup 
will also select AutoCrop and AutoDeskew. This option is only available when scanning in Black&White.
–Despeckle—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, or a small wrinkle, or the holes where a staple was 
removed may show up as speckles on the scanned image. The Despeckle option identifies these spots 
and removes them. This option is only available when scanning in Black&White.
–Color dropout—color dropout is the ability of your scanner to automatically remove a color from a 
scanned image. For example, if you are scanning a letter with a red watermark, you can choose to filter 
out the red so the scanned letter just shows the text and not the red watermark. Color dropout applies to 
Black & White or Grayscale scanning modes.
–Bit depth reduction—Click the drop down menu and select an option from the list. The Bit depth 
reduction options are only available when scanning in black and white.
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.
Dynamic threshold attempts to evaluate the scanned page and automatically adjust the brightness 
and contrast levels to produce the best quality image when scanning in black and white. For example, 
light color text on a page may be missing in the final image as the scanner will change those light colors 
to white pixels. Dynamic threshold will attempt to automatically lower the brightness level to darken the 
image, and raise the contrast level to make the difference between the lighter and darker portions of the 
image clearer.
7. Click OK or Apply to add the Acuity options to your scan configuration.

User’s Guide123 When a scan configuration includes Acuity options, the OneTouch Panel and the OneTouch Properties window both 
show the Acuity icon as a reminder.
The Acuity icon on the top of the 
One Touch Panel and on the scan 
configuration remind you that the 
scan will use the Acuity settings.
The summary of the scan settings 
also indicates Acuity settings.

Accessing the Scanner Interface
Every scanning application will access the scanner using a different method. Below is a brief list of common 
applications and how to initiate a scan from within that application, including some of the applications which may 
have been provided with your scanner. Please refer to the application’s user guide for instructions on using the 
application and accessing the scanner.
•Visioneer OneTouch: Open the Visioneer OneTouch properties window and under the configuration list select 
Configure Before Scan. Click on OK to save the changes and close Visioneer OneTouch. The next time you 
scan using that button, the scanner interface will open for you to set the scan options and start scanning.
•Nuance PaperPort: On the toolbar click on the scanner icon to open the scan pane on the left side of the 
PaperPort desktop. Click on the Select... button to open the scanner selection window. Select either the TWAIN 
or WIA driver for your scanner model and then click OK. If you get a message that the scanner is not in the 
PaperPort database, follow the instruction on-screen to run the Scanner Setup Wizard.
•Nuance OmniPage: Go to To o l s, then select Options.... Click on the Scanner tab, then click on Setup. Follow 
the instructions on-screen to setup OmniPage to work with the scanner. 
Choosing TWAIN or WIA
A note about your scanner and the TWAIN standard:
TWAIN is a widely recognized standard that computers use to receive images from scanners and digital cameras. 
The TWAIN scanning interface can be accessed from any TWAIN scanning application you have installed on the 
computer. The driver interface described herein is the TWAIN driver that has been developed for your scanner. 
The interface described in this section is the one provided with your scanner and you will see it when scanning from 
PaperPort or OmniPage. Other TWAIN compliant scanning applications may also access this interface. However, 
there are some applications that have their own TWAIN interface. If you are scanning from a software application, 
and see the interface shown in this section, you can use these instructions to scan with the TWAIN interface. If you 
do not see this TWAIN interface, please refer to your scanning application’s user guide for instructions.
A note about your scanner and Microsoft WIA (Windows Image Acquisition):
The WIA platform has been developed to enable image transfer from devices using standard Windows applications, 
such as Paint or Windows Fax and Scan, without the need to install additional scanning software. Microsoft has 
developed its own interface for using the scanner with the Windows applications, as well as any other WIA 
compatible applications you may have installed. However, when using a WIA 2.0 compatible application, the default 
behavior will display the TWAIN interface as described in this document. You can change the driver behavior to 
show the Windows interface instead of the custom interface described herein. Please refer to Driver Settings fo r  t h e  
Hardware Properties and Interface Behavior on page 169 for more information. 
Please refer to your Windows documentation for WIA scanning instructions if you do not see the interface described 
below, or if you have any questions regarding Windows scanning applications.
