Printing on different media
This section describes how to print on material other than 
normal Letter/A4 paper.
Printing on legal paper
When printing on legal paper you need to change the media 
settings for the printer software to get the best results.
You can either set a default driver for each type of media or 
you can change the print media settings through your 
Windows printer properties or Mac Print options any time you 
print on different media.
Printing on envelopes
NOTE:
Do not use envelopes with clear windows. Use paper envelopes only.
1.In the Multi Purpose Tray, adjust the paper guides using the 
indicators marked on the printer.
2.Place your envelopes in the tray, face up with the short edge 
facing into the printer and the flap to the right. Do not load more 
than 1 envelope at a time.
3.From your operating system, access the print media menu and 
select your envelope size.
4.Print in the usual manner for your operating system software.

Color Printing
The printer drivers supplied with your printer provide several 
controls for changing the color output. For general use the 
automatic settings will suffice, providing reasonable default 
settings that will produce good results for most documents.
Many applications have their own color settings, and these 
may override the settings in the printer driver. Please refer to 
the documentation for your software application for details on 
how that particular program’s color management functions.
Factors that affect the appearance of prints
I f  y o u  w i s h  t o  m a n u a l l y  a d j u s t  t h e  c o l o r  s e t t i n g s  i n  y o u r  p r i n t e r  
driver, please be aware that color reproduction is a complex 
topic, and there are many factors to take into consideration. 
Some of the most important factors are listed below.
Differences between the range of colors a monitor or 
printer can reproduce
>Neither a printer nor a monitor is capable of reproducing the full 
range of colors visible to the human eye. Each device is restricted 
to a certain range of colors. In addition to this, a printer cannot 
reproduce all of the colors displayed on a monitor, and vice versa.
>Both devices use very different technologies to represent color. A 
monitor uses Red, Green and Blue (RGB) phosphors (or LCDs), a 
printer uses Cyan, Magenta, Yellow and Black (CMYK) toner or 
ink.
>A monitor can display very vivid colors such as intense reds and 
blues and these cannot be easily produced on any printer using 
toner or ink. Similarly, there are certain colors, (some yellows for 
example), that can be printed, but cannot be displayed 
accurately on a monitor. This disparity between monitors and 
printers is often the main reason that printed colors do not match 
the colors displayed on screen.

Viewing conditions 
A print can look very different under different lighting conditions. For 
example, the colors in a print may look different when viewed 
standing next to a sunlit window, compared to how they look under 
standard office fluorescent lighting.
Printer driver color settings
The driver settings for Manual color can change the 
appearance of a print. There are several options available to 
help match the printed colors with those displayed on screen.
Monitor settings
The brightness and contrast controls on your monitor can 
change how your document looks on-screen. Additionally, your 
monitor’s color temperature influences how “warm” or “cool” 
the colors look.
There are several settings found on a typical monitor:
>5000k  Warmest; yellowish lighting, typically used in graphic art 
environments.
>6500k  Cooler; approximates daylight conditions.
>9300k  Cool; the default setting for many monitors and television 
sets.
(k = degrees Kelvin, a measurement of temperature.)
How your software application displays color 
Some graphics applications such as Corel Draw or Adobe 
Photoshop may display color differently from “Office” 
applications such as Microsoft Word. Please see your 
application’s on-line help or user manual for more information.
Paper type 
The type of paper used can also significantly affect the printed 
color. For example, a printout on recycled paper can look duller 
than one on specially formulated high-quality paper.

Tips for printing in color
The following guidelines may help you to achieve good color 
output from your printer.
Printing photographic images
Use the Monitor (6500k) Perceptual setting. 
If the colors look too dull, try the Monitor (6500k) Vivid or 
Digital Camera settings.
Printing from Microsoft Office applications
Use the Monitor (9300k) setting. This may help if you are 
having problems with specific colors from applications such as 
Microsoft Excel or Microsoft Powerpoint.
Printing specific colors (e.g. a company logo)
There are 2 utilities on your printer driver CD-ROM that can 
help match specific colors:
Color Correct Utility 
Color 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 colors are too intense/not intense enough, use the 
Saturation control.

Accessing the color matching options
The Color Matching options in the printer driver can be used to 
help match your printed colors to the ones displayed on your 
monitor or from some other source, such as a digital camera.
To open color 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 color 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 color matching options
1.On the Color tab select Advanced Color  for Color Matching.   
2.Choose the Manual color setting and select from the following 
options:    
(a)Monitor (6500k) Perceptual
optimized for printing photographs. Colors are printed with 
emphasis on saturation.
(b)Monitor (6500k) Vivid
optimized for printing photographs, but with even more 
saturated colors than the Monitor (6500k) Perceptual 
setting.
(c)Monitor (9300k)
optimized for printing graphics from applications such as 
Microsoft Office. Colors are printed with emphasis on 
Lightness. 
(d)Digital Camera
optimized 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.

may be useful if color matching from an sRGB input device 
such as a scanner or digital camera.

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

Using the Color Correct Utility
The Oki Color 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 Color Correct utility has the following features:
>Microsoft Office palette colors can be individually adjusted. This is 
useful if you want to change how a specific color is printed.
>Colors can be adjusted by changing Hue, Saturation and Gamma. 
This is useful if you wish to change the overall color output. 
Once these color adjustments have been made, the new 
settings can be selected from the printer driver Color tab.
To select adjustments made with the Color 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 Color tab.
4.Click Advanced Color.
5.Click User Defined.
Select the color adjustment you made with the Color Correct 
Utility.
