Technical Note:

If you are getting false double feed errors, try cleaning the inside of the scanner. Excessive dust on 

the sensor can cause false double feed errors. Refer to the maintenance section of the scanner's 

user guide for instructions on cleaning the scanner.

Straighten Image

Select this option to let the scanner automatically determine if a page is skewed, then straighten 

its image. This option is only available if the scanner supports this feature.

If you are scanning using an automatic document feeder, and the page is fed through at too 

great of an angle, the image may not straighten correctly. In that case, re-scan the page making 

sure the paper guides are adjusted to the width of the pages in the input tray so that the pages 

are pulled straight through the scanner.

Rotate Image

Select an option in this list to have the final image rotated when scanning is complete.

Flip Back Side

Select this option if you are scanning duplex pages that are calendar style orientation. This option 

will rotate the back side image 180 degrees from the front side. When scanning in duplex mode 

without this option selected, the back side image of calendar orientation pages will appear upside 

down in the final scan. This option does not automatically determine book page orientation 

versus calendar page orientation. If you have this option selected when scanning book orientation 

pages, the image for the back side of the page will appear upside down in the final scan. If you are 

scanning a batch of documents that contain both types of orientation, we recommend that you 

select Automatic in the Rotate image list. 

This option is available only if the current scanner supports duplex scanning and the Duplex 

option is selected in the scanning interface.

Merge Two Sides

When scanning in duplex mode, you can enable this option to have both sides of a scanned item 

appear on one page in the final image file. The options in the list allow you to select where you 

want the front side image to appear in relation to the back side image in the final file.
