Noise filter —these options are available to help increase the compression
ratio and improve the appearance of document images.
• Majority Rule—determines central pixel data according to the number of
white and black pixels.
• None—no enhancement is done to the images.
• Lone Pixel—reduces random noise on bitonal images by converting a black
pixel surrounded by white pixels to white and by converting a white pixel
surrounded by black pixels to black.
NOTES: Using the noise filter on documents containing very fine detail
(e.g., the dot on an “i” in 4-point type) may cause information to
be lost. It is recommended that the noise filter not be used when
scanning documents with text smaller than 7-point type.
Using the noise filter in conjunction with thresholding will optimize
the appearance of document images.
Do not use the noise filter with screening (dithering).
Image filter —select None or Halftone removal. Halftone removal is used to
enhance images. containing dot matrix text and/or images with shaded or color
backgrounds using halftone screens. This filter effectively eliminates noise
caused by the halftone screens.

JPEG Quality —JPEG quality controls the amount of file compression
performed by the scanner when producing JPEG images. Select Draft, Good,
Better, Best or Superior. The Draft and Good settings increase image
compression (resulting in smaller file sizes), but decreases image quality. The
Best and Superior settings decrease image compression (resulting in larger
file sizes), but improves image quality.
Color table —the selected color table affects how the scanner reproduces
the color of a scanned document. Select a color table from the drop-down
list. Use the
Photo table for scanning pictures and the Text table for text
documents with color content. Mixed tables are recommended for documents
that contain both text and pictures.
