SYMPTOMS
When you scan a document, and then recognize the text using Optical Character Recognition (OCR), the OCR portion of the scan takes longer than you expect.



CAUSE
This behavior can occur when you use OCR on a document that has a dark or &quot;noisy&quot; background; for example, a document that has been repeatedly photocopied.



WORKAROUND
To work around this behavior, scan the document again to obtain a clearer image with which to use OCR.



MORE INFORMATION
When you use OCR on a document of low image-quality, the OCR recognizer can interpret background marks as text that needs to be recognized. This may add more time to the recognition of the document.
