Calibrate the screen. See Chapter 3.
Make sure the Image Type (page

settings (page 4-11) are correct.
Printed colors will not exactly match
the colors on your monitor, since
printers and monitors use different
color systems: monitors use RGB (red,
green, and blue), while printers
typically use CMYK (cyan, magenta,
yellow, and black).
What to do
Select a different Resolution setting
on the OCR/Line Art menu.
Try adjusting the Threshold setting
on the OCR/Line Art menu.
