Scanning Basics

2-29

If you still have problems...

1. In the Manual mode window, increase the

Resolution

value

to 400. Remember that scanning at higher resolution takes
longer and may not increase the recognition rate much.

2. If you still have problems, try using the enhancement tools in

your OCR software to make adjustments.

Potential Text Recognition Problems

The quality of the text in your original document greatly effects
OCR results.

The following types of originals can make recognition difficult
and should be avoided if possible:

❏

Items that have been copied from other copies

❏

Faxes

❏

Text with tightly-spaced characters or line pitch

❏

Text that is in tables or underlined

❏

Cursive or italic fonts, and font sizes less than 8 points

Remember that OCR software cannot recognize handwritten
characters.
