Tips for Getting the Best Results

■ When characters are light or broken, use a lower (darker) setting.

However, when there are both broken and touching characters on the same page or

in the same document, trying to fix one problem may make the other problem

worse.

In such a situation, you’ll usually find that it works to use this rule:

■ When there are both broken and touching characters, use a lower (darker)

setting—that is, fix the broken characters.

It’s usually better to decrease the brightness level (darken the image) to compensate

for the broken or light characters, even though by doing so you may increase the

number of dark or touching characters.

Because light or broken characters are more of a problem than dark or touching

characters, decrease the brightness just enough to compensate for the broken

characters.

Adjusting Brightness for Consistent Documents

For most documents, you’ll find that using Auto OCR works well. Auto OCR is

most useful when the pages in your document are consistent:

■ The same page size and orientation

■ The same printing source

■ The same photocopy generation (that is, how many times the page has been

recopied). The quality of the character image degrades each time you make a

photocopy of a photocopy (that is, a “second generation photocopy”).

When you adjust the brightness setting in your scanner software to compensate for

poor photocopies, you may find that different “generations” of photocopies need

different brightness settings.

To find the correct Brightness setting:

1. In your scanner software, increase or decrease the brightness setting.
