◦ If you are using a separate OCR (optical character recognition) program,
the OCR program might be linked to a word-processing program that does
not perform OCR tasks. For more information, see the documentation
provided with the OCR program.
◦ Make sure you have selected an OCR language that corresponds to the
language used for the document you are scanning. For more information,
see the documentation provided with the OCR program.
• Check the originals
◦
When scanning documents as editable text from the ADF, the original must
be loaded into the ADF with the top forward and face up. When scanning
from the scanner glass, the original must be loaded with the top facing the
right edge of the scanner glass. Also, make sure the document is not
skewed. For more information, see Load an original on the scanner glass or
Load an original in the automatic document feeder (ADF).
◦ The software might not recognize text that is tightly spaced. For example, if
the text that the software converts has missing or combined characters, "rn"
might appear as "m."
◦ The accuracy of the software depends on the image quality, text size, and
structure of the original and the quality of the scan itself. Make sure that
your original has good image quality.
◦ Colored backgrounds can cause images in the foreground to blend too
much.

Scanned image quality is poor
The original is a second-generation photo or picture
Reprinted photographs, such as those in newspapers or magazines, are printed by
using tiny dots of ink that make an interpretation of the original photograph, which
degrades the quality. Often, the ink dots form unwanted patterns that can be detected
when the image is scanned or printed or when the image appears on a screen. If the
