Improving Accuracy

 38  How to Improve Performance

Paper Transparency

Some paper is thin enough that the scanner sees text printed on the 
opposite side of the scanned page. This is often the case with telephone-
book pages. To correct this problem, put a black piece of paper behind the 
page between the page and the lid of the scanner.
