Threshold
Adjusts the level at which black areas in text and line art are delineated, improving text recognition in
OCR (Optical Character Recognition) programs.

select Grayscale or Black & White as the Image Type setting.
Brightness

Contrast
Adjusts the difference between the light and dark areas of the overall scanned image.
Gamma
Adjusts the midtone density of the scanned image.
Unsharp Mask
Makes the edges of certain image areas clearer. Turn off this option to leave softer edges.

option improves results when scanning magazines or newspapers. (The results of descreening do not
appear in the preview image, only in your scanned image.)
Skip Blank Pages
If the scanner detects marks from the other side of a blank page and adds the marks to the scanned
image, adjust this setting to prevent this.
Edge Fill
Corrects shadowing around the edges of the image by filling the shadows with black or white.
Correct Document Skew
Corrects skewed originals, image contents, or both.

Saving Scanned Documents as a Searchable PDF

You can scan a document and save the text in a searchable PDF. In a searchable PDF, text is
recognized using Optical Character Recognition (OCR) and then embedded in the scanned original.
Note: The required Epson Scan 2 OCR Component is installed automatically when you install your
product software as instructed on the Start Here sheet. If you install your scanner software programs
individually, be sure to also install this component if you want to perform OCR.
