Setting the Color Registration for
Windows 95 / 98 / NT 4.0

Since each color is printed separately, you must set the color
registration to ensure that the colors line up properly. If the

blurry and unclear.

To ensure optimum print quality, you should set the color
registration on a routine basis (once a month or so).

when you change toner or image drums, when you load paper
in the paper tray, or if you move the printer.

To set the color registration:

®

Programs ® OKICOLOR 8 ® OKICOLOR 8 Color

color shows in the spaces between the black lines and note
its corresponding number.

If more than one box has no color, select the one closest
to zero. If all the boxes have color, select the lightest
one, nearest zero.

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.

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.

When to use the Color Balance Utility

• When you replace an image drum.

• 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.

Using the Color Balance Utility

Start the utility:

• 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.

1 Make sure the OKICOLOR 8 is selected as the active

printer.

2 Click Reset and Print Adjustment Page to print the color

balance adjustment page.

|

Handy Reference 37

Look at the color balance adjustment page:

• 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.

4 Click Apply Changes and Print Verification Page. This

calibrates the printer and prints a color balance verification
page that confirms the new settings.

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

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.

The menu settings page prints.

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.

!

See the on-line OKICOLOR 8 User’s Guide for
additional print quality symptoms and solutions.

Colors do not print as expected.

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.

46

OKICOLOR 8

|

Colors are shifted or not lined up
properly.

Reason:

Color registration is incorrect.

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.

Blank sheets printed/one or more
colors missing.

Reason:

Empty or missing toner cartridge.

Solution:

Install new toner cartridge.

Reason:

Image drum contacts may have failed.

Solution:

Remove the appropriate image drum(s) and examine the
contacts on the left side of the drum and on the left side inside
the printer. Clean them if necessary, then reinstall the image
drum(s).

Reason:

LED array connection may have failed.

Solution:

Contact your service representative.

|

Handy Reference 47

Entire page or one color prints faintly.

Reason:

Empty toner cartridge. Pages get fainter after toner is used up.

Solution:

Install new toner cartridge.

Reason:

LED array is dirty.

Solution:

Clean the LED array.

Reason:

Image drum may be near its end of usable life.

Solution:

Replace the image drum.

Page prints all one color.

Reason:

Hardware problem

Solution:

Contact your service representative.

48

OKICOLOR 8

|

Page has gray or speckled
background.

Reason:

Static electricity causes toner to stick to background.

Solution:

Change paper to an acceptable laser bond and use a
humidifier.

Horizontal bands of darker print at
regular intervals down the page.

Reason:

Image drum has been exposed to light.

Solution:

Leave the printer turned off for about two hours. If this fails
to restore it, install a new image drum cartridge.
