Noise Filter
• None
• Lone Pixel: reduces random noise by converting a single black pixel
to white when it is completely surrounded by white pixels or by
converting a single white pixel to black when it is completely
surrounded by black pixels.
• Majority Rule: sets each pixel based on its surrounding pixels. The
pixel will become white if the majority of the surrounding pixels are
white and vice versa.
• Background: locates and analyzes the background areas of the
image (e.g., non-text areas) and reduces random noise that may be
multiple pixels in size.
Text Enhancement — allows you to configure the scanner to improve
the appearance of text. Turn this option on if your document is mostly
text and the characters are disconnected or not smooth. This option
improves the readability of dot matrix printing and improves poor quality
characters if the font size and/or resolution is large/high enough.
NOTES:
• This may have no effect on small fonts and effectiveness may be
diminished if Thinning/Thickening is being used.
• If the font size is too small or the resolution is not high enough, this
option may cause characters to fill in.
Thinning/Thickening — allows you to make the lines and characters
appear to be thinner or thicker. Decreasing this setting will make the
lines and characters thinner/smaller. Increasing this setting will make
the lines and characters thicker/larger. The default is 0, no thinning or
thickening.
