OPERATION
HOW TO ACCESS THE DRIVER SCREENS
Most of the features described are accessed via the printer driver 
windows. How you access them depends on your computer and its 
operating system.
The driver windows are tabbed dialogue boxes, offering a wide range 
of choices about how you want to print your documents.
There are two ways to access the driver features:
1.Directly from the Windows “Printers” folder (“Printers and 
Faxes” folder in Windows XP).
If you choose this method any changes you make will become 
the driver defaults. This means they will remain active for all 
your applications unless you specifically change them from 
within the application’s Print dialogue.
2.From your application’s Print dialogue.
If you choose this method any changes you make will usually 
only last for as long as the particular application is running, or 
until you change them again. In most cases, once you quit the 
application the driver defaults will return.
CHANGING THE DRIVER DEFAULTS
WINDOWS XP/2000
1.Click [Start] → [Settings] → [Printers and Faxes] to open the 
Printers and Faxes window.
IMPORTANT!
Settings made from the printer’s own control panel are 
the printer defaults. They determine how your printer 
will behave unless you specify otherwise from your 
computer.
The driver defaults override the printer defaults.
Application Print settings override both the printer 
defaults and the driver defaults.

shown is the appropriate one, and click [Properties].
DRIVER SETTINGS
This feature allows you to save the printer driver settings and reuse 
them later. This could be useful if you frequently print many different 
types of document that require different printer driver settings.
Recalling saved settings is a simple task that must be done first, 
before any job-specific changes are made. Rather than repeat the 
procedure throughout this manual, it is described here.

SETTING THE DRIVER DEVICE OPTIONS
This section explains how to ensure that your printer driver can 
utilize all of the hardware features installed in your printer.
Accessories such as hard disk, duplex unit (two sided printing), 
additional paper trays, etc., will only be usable if the printer driver 
on your computer knows they are there.
In some cases the hardware configuration of your printer is 
automatically detected when the driver is installed. However, it is 
advisable to at least check whether all of the available hardware 
features are listed in the driver.
This procedure is essential if you subsequently add extra hardware 
features to your printer after the drivers have been installed and set 
up.
To set the driver device options:
1.Access the driver’s [Properties] window.
2.Select the [Device Options] tab.
3.Set the options for any devices you have installed, including 
the correct number of paper trays, finisher, duplex unit, etc.
4.Click [OK] to close the window and save your changes.

PRINTING BLACK
BLACK GENERATION
You can specify whether black graphics in color documents are 
printed using:
>Composite Black
>Pure Black
Pure Black is the default setting.
COMPOSITE BLACK
The cyan, magenta, yellow, and black toners are combined to create 
composite black. This will sometimes give a glossier finish due to the 
increased amount of toner. It can also appear as a slightly brownish 
black.
PURE BLACK
Only black toner is used to print pure black.

COLOR MATCHING
FACTORS THAT AFFECT COLOR PRINTING
There are many factors that affect color printing. Some of the most 
important factors are:
> the differences between the range of colors a monitor can 
reproduce versus the range of colors that a printer can 
reproduce (See page 49).
> monitor settings (See page 50).
> color settings in your software application (See page 51).
> how your software application displays color (See page 51).
> color settings in your printer driver (See page 51).
> viewing (lighting) conditions (See page 51).
> paper type (See page 51).
MONITOR COLORS VS. PRINTER COLORS
(Differences between the range of colors a monitor or printer can 
reproduce)
Neither a printer nor a monitor can reproduce the full range of colors 
seen by the human eye. Each device is limited to a certain range of 
colors.
> A printer cannot reproduce all of the colors displayed on a 
monitor.
> A monitor cannot reproduce all of the colors printed by a 
printer.

Both devices use very different technologies to represent color.
> A monitor uses Red, Green and Blue (RGB) phosphors (or 
LCDs).
> A printer uses Cyan, Yellow, Magenta and Black (CMYK) toner 
or ink. 
Very vivid colors (such as intense reds and blues) can be displayed 
on a monitor. These same colors cannot be easily produced on any 
printer using toner or ink.
There are certain colors (for example, some yellows), that can be 
printed, but cannot be displayed accurately on a monitor.
These differences between monitor colors and printer colors are the 
main reasons why printed colors do not always match the colors 
displayed on screen.
MONITOR SETTINGS
The brightness and contrast controls on your monitor can change 
how your document looks on-screen.
Your monitor color temperature also influences how “warm” or “cool” 
the colors look. 
Several of the color matching options make reference to your 
monitor’s color temperature.
Many monitors allow you to adjust the color temperature through 
their control panels.
There are several settings found on a typical monitor:
k=degrees Kelvin, a measurement of temperature 5000k or D50 Warmest, yellowish 
lightingTypically used in graphics arts 
environments.
6500k or D65 Cooler Approximates daylight conditions.
9300k Cool The default setting for many monitors 
and television sets.
