Picture Processing 
This setting determines whether to look for text within pictures. Your choices 
are: 
Text & Pictures: Use this setting when you want the text conversion engine to 
attempt to locate text that resides in regions on the page that it views as 
pictures. 
Text Only: The text conversion engine does not attempt to locate text that 
resides in regions on the page that it considers to be pictures. 
Quality of  
Input Image 
This setting tells the text conversion engine about the quality of the image it is 
about to process. Your choices are: 
Letter: This is appropriate for most documents. 
Dot Matrix: Use this setting when characters in the input document are printed 
in a mono-spaced font and made up of dots that are not touching. 
Degraded Quality: Check this item when the input text is severely degraded or 
is hard to read. This will significantly slow down the text conversion 
processing. 
Miscellaneous 
Custom Dictionary: Clicking this button invokes a standard File Find dialog 
box letting you select a custom dictionary file (.DIC). Custom dictionary files 
improve the recognition ability when processing uncommon words. Sharpdesk 
comes with a simple custom dictionary, 
USER.DIC
, that will be selected by 
default. If you are converting a document that contains technical terms that 
aren’t commonly used, you can place these terms in a your custom dictionary 
separated by line breaks. Use Microsoft® Notepad or other similar editors to 
make changes to your custom dictionaries or create new ones. 
Language: Lets you select a language setting for the text conversion engine. 
Illegible Character: Lets you specify the character that the text conversion 
engine outputs when it cannot read a character. The default is “~”. 
Show this dialog box every time OCR is performed: Checking this item 
forces this property dialog box to be displayed every time you perform OCR, 
giving you an opportunity to change the settings. 
Text Conversion Tips 
If you do not get the results you want when you convert an image to text, you might check the 
following items: 
• 
Check your scanning options. You might have the brightness or contrast levels set too high 
or too low.   
• 
Check your text conversion preferences.  
• 
Clean your scanner glass and scanner lid with a soft cloth. 
• 
Reposition the document on the scanner glass. 
• 
Change your Quality of Input Image settings.  Sometimes an image can be converted by 
using the Dot Matrix or Degraded Quality settings. 
• 
Be sure you have sufficient disk space to hold the temporary files that the text conversion 
engine creates.
