TIPS FOR PRINTING IN COLOUR
The following guidelines may help you to achieve good colour 
output from your printer.
PRINTING PHOTOGRAPHIC IMAGES
Use the Monitor (6500k) Perceptual setting. 
If the colours look too dull, try the Monitor (6500k) Vivid or 
Digital Camera settings.
PRINTING FROM OFFICE APPLICATIONS
Use the Monitor (9300k) setting. This may help if you are having 
problems with specific colours from applications such as Microsoft 
Excel or Microsoft PowerPoint.
PRINTING SPECIFIC COLOURS (E.G. A COMPANY LOGO)
There are 2 utilities on your printer driver CD-ROM that can help 
match specific colours:
Colour Correct Utility 
Colour Swatch Utility 
ADJUSTING THE BRIGHTNESS OR INTENSITY OF A PRINT
If the print is too light/dark, you can use the Brightness control 
to adjust it. 
If the colours are too intense/not intense enough, use the 
Saturation control.

ACCESSING THE COLOUR MATCHING OPTIONS
The colour matching options in the printer driver can be used to 
help match your printed colours to the ones displayed on your 
monitor or from some other source, such as a digital camera.
To open colour matching options 
from the Windows Control Panel:
1.Open the  Printers window 
(called “Printers and Faxes” 
in Windows XP).
2. Right-click the printer name 
and choose  Properties.
3. Click the  Printing 
Preferences  button (1).
To open colour matching options from within a Windows 
application:
1. Choose  File>Print…  from the application’s menu bar.
2. Click the  Properties  button next to the printer name.
SETTING THE COLOUR MATCHING OPTIONS
1.On the  Colour tab select  Advanced Colour  for colour 
matching.

2.Choose the Manual colour setting and select from the 
following options:
(a)Monitor (6500k) Perceptual
Optimised for printing photographs. Colours are 
printed with emphasis on saturation.
(b) Monitor (6500k) Vivid
Optimised for printing photographs, but with even 
more saturated colours than the Monitor (6500k) 
Perceptual setting.
(c) Monitor (9300k)
Optimised for printing gr aphics from applications 
such as Microsoft Office. Colours are printed with 
emphasis on Lightness. 
(d) Digital Camera
Optimised for printing photographs taken with a 
digital camera. 
Your results will vary depending on the subject and 
the conditions under which the photograph was 
taken.
(e) sRGB
The printer will try to reproduce the sRGB colour 
space. This may be useful if colour matching from an 
sRGB input device such as a scanner or digital 
camera.

USING THE COLOUR SWATCH FEATURE
To use the Colour Swatch feature, you must install the Colour 
Swatch Utility. This is supplied on the CD-ROM that was supplied 
with your printer.
The Colour Swatch function prints charts which contain a range 
of sample colours. Note that this is not the full range of colours 
that the printer can produce. Listed on each sample colour are 
the corresponding RGB (Red, Green, Blue) values. This can be 
used to pick specific colours in applications that allow you to 
choose your own RGB values. Simply click the Colour Swatch 
button (1) and choose from the options available.
An example of using the colour swatch function:
You wish to print a logo in a particular shade of red. The steps 
you would follow are:
1. Print a colour swatch, then select the shade of red that 
best suits your needs. 
2. Take a note of the RGB value for the particular shade that 
you liked.
3. Using your program’s colour picker, enter these same RGB 
values, and change the logo to that colour.
The RGB colour displayed on your monitor may not necessarily 
match what was printed on the colour swatch. If this is the case, 
it is probably due to the difference between how your monitor 
and printer reproduce colour. Here, it is unimportant since your 
primary objective is to print the required colour.

USING THE COLOUR CORRECT UTILITY
The Oki Colour Correct Utility is provided on your printer driver 
CD-ROM. You must install it separately since it is not installed 
along with the printer driver.
The Colour Correct utility has the following features:
>Microsoft Office palette colours can be individually 
adjusted. This is useful if you want to change how a 
specific colour is printed.
> Colours can be adjusted by changing Hue, Saturation and 
Gamma. This is useful if you  wish to change the overall 
colour output. 
Once these colour adjustments have been made, the new 
settings can be selected from the printer driver Colour tab.
To select adjustments made  with the Colour Correct 
Utility:
1. From your application program, click  File and point to 
Print .
2. Click Properties . This displays the printer driver options.
3. Click the  Colour tab.
4. Click Advanced Colour .
5. Click User Defined .
Select the colour adjustment you made with the Colour Correct 
Utility.

items in the menu. When the item you want to change is

appears next to the setting currently in effect.
3. Use the +/– buttons to move up and down through the 
available settings for this item, and press  ENTER when 
the setting you want is displayed. An asterisk (*) will 
appear next to the setting, indicating that this setting is 
now in effect.
4. Press BACK  to move back to the list of menu items.

MEDIA MENU
This menu provides adjustment to suit a wide range of print 
media.
MONO-PRINT 
SPEED AUTO
NORMAL SPEED
COLOR SPEED If the first page of a print job is black and 
white, the printer runs at 32ppm (pages 
per minute). When a colour page is 
detected the printer slows down to 26ppm 
for the rest of that job.
This setting operates in the same way as 
AUTO SPEED, except that the printer runs 
at 32ppm until a colour page is detected. 
To achieve this speed the printer requires 
an additional time to warm up and cool 
down when switching to 26ppm for colour 
pages. This setting is therefore most 
appropriate when the majority of print 
jobs are entirely black and white.
The printer runs at 26ppm for all print 
jobs. This setting is most appropriate 
when the majority of print jobs are in 
colour.
