Scanning with the TWAIN Interface
86 DocuMate 752 Scanner User’s Guide
6. AutoCrop—Select this option to let the scanner automatically
determine the size of the item being scanned. For example, if
you scan a 5”x 7” photo, the scanner will determine the size of
the photo.
For single-sided scans, the scan area is the size of the image.
For double-sided scans, the scan area is the size of the larger
of the two areas on the front and back of the page.
7. Straighten—Select this option to let the scanner automatically
determine if a page is skewed, then straighten its image. The
scanner detects page edges and can sense when the page is
fed through at an angle. However, if the page is fed through at
too great an angle, the image may not straighten correctly. In
that case, re-scan the page using the paper guides to feed the
paper in straight.
8. Click the Preview
button.
The scanner scans the item and displays a preview image. If
you selected the Autorotate 90 option, the preview image is
not rotated until the final scan is completed.
You can now use the options on the Basic Interface to adjust
the image.
9. Adjust the Brightness, Contrast, and Resolution until the
picture is what you want. You can also change the picture type
again, for example, from color to grayscale.
10. When you are satisfied with the preview image, remember to
place the document into the ADF again if you’re scanning a
stack of pages. Click Scan.
11. When you’re finished scanning items, click Done to close the
Basic Interface.
12. The scanned images will appear in the TWAIN application
you’re using.
NOTE: If you want to preview a stack of pages, use one of the
pages as a test page and load it into the scanner. Click the
Preview button and adjust the scanner settings. Then replace
the page on the stack at its original position and load the stack
into the scanner. Then just click the Scan button.
