• For example, if you are scanning a document with gray text, such as hand written pencil notes,
move the slider towards Light. This tells the scanner that the level to look for is light, and gray
pixels are converted to black pixels instead of white. If the overall tone of the original document is
dark, such as a colored background that may interfere with detecting black, move the slider
towards Dark. This tells the scanner that the level to look for is dark, only very dark areas such as
text are converted to black pixels.
