Improving Copy
Quality
4-9 Copy Quality
3 What is the first thing I should do if the image colors do not
look right?
Use the Color Balance Adjustment Page to adjust the print den-
sity. See “About Print Density” on page 2 for details on how to
adjust the print density.
4 I used the Color Balance Adjustment Page to adjust the
printer color, but the scanned image color is still not right.
Usually the default settings balance the printer. However, you
might have to make minor adjustments to color balance,
brightness, and contrast to improve image quality. When
adjusting the brightness and contrast, remember to compare the
original image against each copy in the same well lit area. Lay the
images side by side so you can make a direct comparison.
After you think the brightness and darkness are right, check to
see if there is too much color. For example, if the image has too
much green, access Copier/Color Balance and move the arrow
towards magenta (move it one level at a time). Then scan the
image and look at the colors.
» Note: Keep in mind that the lower the resolution, the less time it
takes to copy the image. So scan the image at 100 dpi to save
time. Then once you’re satisfied with the colors, increase the
resolution to 200 dpi for a higher quality scan.
5 Why do I have little square boxes and lines in the scanned
image when they aren’t in the original?
These are mostly moíre patterns. They’re caused by halftones in
the original image. Take a small magnifying glass and look at the
original (it appears as a collection of small dots). The scanner
reads the dots and the printer tries to recreate the dot image. This
produces the resultant moíre patterns.
6 How do I get rid of these little square boxes and lines in the
scanned image?
You can try scanning at different resolutions and also try using the
Administration/PostScript/Default Halftone/Color Smooth option.
