Since each color is printed separately, you must set the color
registration to ensure that the colors line up properly. If the
colors are out of alignment, the printed page will appear
blurry and unclear.

Using the Color Balance Utility
Start the utility:
Setting the Color Balance
Important!
Be sure to check your printer’s color registration before you
use the color balance utility. See “Setting the Color
Registration” for details.
• Windows systems: click Start
Programs
OKICOLOR 8
OKICOLOR 8 Color Balance
Utility.
• Macintosh systems: in the OKICOLOR 8 Macintosh
Folder, double-click the Color Balance Utility.
The Color Balance Utility program, which is normally loaded
when you install your printer software, replaces the color
balance item built into the printer’s control panel menu. Use
this program to make sure that the three primary colors your
printer uses—cyan, magenta, and yellow—are properly
balanced. If they are not properly balanced, one color may
dominate, and printed pictures will not be as lifelike as they
could be.
1 Make sure the OKICOLOR 8 is selected as the active
printer.
When to use the Color Balance Utility
• When you replace an image drum.
2 Click Reset and Print Adjustment Page to print the color
balance adjustment page.
• Whenever you feel the color reproduction of your printer
is not accurate.
• When you set up your printer for the first time, after
performing the color registration procedure.

Look at the color balance adjustment page:
4 Click Apply Changes and Print Verification Page. This
calibrates the printer and prints a color balance verification
page that confirms the new settings.
• The pattern consists of a series of rectangles on a gray
background.
• Look for the rectangle that matches the gray
background most closely. You may not find one that
matches exactly; select the one that you think matches
best.
3 Enter the column letter and row number of the best
matching rectangle in the Column and Row boxes on the
screen.
5 Click Close.
Important!
Do not go back to step 2 to check the color balance. The
utility resets the printer to its default settings every time it
prints the color balance adjustment page.

Print Quality Problems
Overview
The printer uses separate cartridges of cyan, magenta, yellow
and black toner to generate high definition color images.
Factors causing print quality problems may affect only one
color, or several colors, so the results may be unpredictable.
Solution:
The Color Options tab on your computer screen provides a
list of color matching techniques and adjustments to provide
color balance in your document.
You can use the color bars at the bottom of the menu settings
page to help isolate which color is causing the problem. To
print the menu settings page, press and hold Print Menu for
several seconds.
See the on-line OKICOLOR 8 User’s Guide for
additional print quality symptoms and solutions.
!
Colors do not print as expected.
The menu settings page prints.
Reason:
A computer monitor and a printer use different methods to
generate colors based on a different set of primaries —Red,
Green and Blue (RGB) for monitors, Cyan, Magenta, Yellow
and Black (CMYK) for printers. This may lead to a color
print not resembling the original on-screen image.

Colors are shifted or not lined up
properly.

Reason:

Solution:
Solution:

Color registration needs to be reset. See “Color Registration.”
It is recommended that you reset color registration when you
change toner or image drums, when you load paper in the
paper tray, or if you move the printer.
Reason:

Solution:
Remove the appropriate image drum(s) and examine the

the printer. Clean them if necessary, then reinstall the image
drum(s).
