Load OCR when Direct is Launched
32 How to Improve Performance
Direct is designed to run automatically, making text recognition easy and
effortless. However, the automatic features take longer to work. De-
selecting Use Language Analyst, Auto Intensity, and manually setting other
options will make Direct run much faster.
The Language Analyst automatically performs word and character
analysis during recognition to check spelling and replace unknown words
with words that are most likely to be correct.
Speed up Direct by deselecting Use Language Analyst. The Language
Analyst improves recognition accuracy but increases the processing time.
The Use Language Analyst selection is available by choosing Spelling... in
the Direct icon Control menu (click once on the minimized Direct icon on
the Windows desktop).
The Auto Intensity feature, available with grayscale scanners, improves
accuracy considerably if your page is dirty, if text is printed on a colored
background, or if the page has shading from a copy machine.
However, if you scan high-quality documents with crisp, black letters
printed on white paper, recognition is much faster with this setting turned
off. Deselect Auto Intensity in the Options dialog box and use the manual
Brightness control.
Select Fully formed when you scan conventionally printed text characters.
Select Dot matrix when you scan characters printed in draft mode by a 9-
pin dot-matrix printer. Do not select Dot matrix for pages printed in near-
letter-quality mode or printed by a 24-pin dot-matrix printer.
Select Single column/Tables when there is one column on a page, as with
correspondence, or when scanning a table, financial form, or spreadsheet.
Select this if you want Direct to load the optical character recognition
(OCR) program in your computer's memory when Direct is started. Direct
will take a few seconds to load OCR, and then there will be no delay the
first time you scan a page.
