print on both sides of the paper.

Print quality
Print quality
Use this option to select the print resolution. The High 
Quality (ProQ2400) setting produces the best graphic 
images, but these images can take longer to print.
Photo Enhance
Use Photo Enhance to significantly improve quality when 
printing images. The printer driver analyses any 
photographic images and processes them to improve the 
overall appearance. This setting cannot be used together 
with the ProQ2400 print quality setting.
Toner Saving
Toner saving uses less toner when printing your document. 
This is best suited to draft text documents as it lightens the 
print significantly.

Color matching 
Black Finish
Use this option to control the way black is printed in colour 
documents. Select Composite Black (CMYK) to uses all 4 
toner colours to represent black. This option is 
recommended for color photos. Select True Black (K) to 
uses 100% black toner to represent black. This option is 
recommended for text and business graphics.
Brightness / Saturation
This option allows you to increase brightness for a lighter 
print. Modify saturation to change the strength (or purity) 
of a colour.
If the printed colours are too strong, reduce saturation and 
increase brightness. As a general rule, reduce saturation 
by the same amount as you increase brightness. For 
example, if you reduce saturation by 10, increase 
brightness by 10 to compensate.
COLOURDESCRIPTION
Monitor (6500K) Perceptual Optimised for printing photos.  Colors are printed with 
emphasis on saturation.

colors.

Microsoft Office. Colors are 
printed with emphasis on 
Lightness.
Digital Camera Results wi ll vary depending on 
the subject and conditions the

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

PRINTER SETUP OPTIONS
Printer options
Media weight
Select the thickness or type of paper in the printer. It is 
important to set this correctly as it affects the temperature 
at which the toner is fused to the paper. For example, if 
you are printing on normal A4 paper, do not select Labels 
or Transparency as this may cause toner smearing and 
paper jams.
Auto tray switch
If the printer runs out of paper in the current tray, Auto 
Tray Switch automatically changes to a tray that has the 
same type of paper and continues printing.
Paper size check
Select Paper Size check if you want the printer to warn you 
when the document paper size is different from the paper 
in the printer.
A warning message is displayed and printing continues 
when you load the correct paper in the paper tray and 
press ONLINE. When this option  is deselected, the printer 
uses the paper loaded in the se lected tray regardless of the 
document size.

Feed manually from Multipurpose Tray
Select this option if you want the printer to wait until you 
press the ONLINE button when feeding from the 
Multipurpose Tray. This can be useful if printing on 
envelopes.
Always create 100% black (K) toner
Select this option if you want the printer to always use only 
black (K) toner when printing pure black (RGB = 0,0,0). 
This is effective even when Composite Black (CMYK) is 
selected in the colour options.
Run maintenance cycle before printing
Depending on printing habits  and usage patterns, running 
the maintenance cycle before printing may ensure the best 
possible print quality. This feature uses the printers image 
drums and transfer belt. The life of these printer 
consumables may be shortened if the printer runs a 
maintenance cycle frequently.
Print control
If you are using the Windows Print Control Server software to 
manage printers, enter your assigned user name and ID. This 
information is sent to the printer with your print job and is 
recorded by the printer.

COLOUR PRINTING
The printer drivers supplied with your printer provide several 
controls for changing the colour 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 colour 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 colour management functions.
FACTORS THAT AFFECT THE APPEARANCE OF PRINTS
If you wish to manually adjust the colour settings in your printer 
driver, please be aware that colour 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 colours
a monitor or printer can reproduce
> Neither a printer nor a monitor is capable of reproducing 
the full range of colours visible to the human eye. Each 
device is restricted to a certain range of colours. In 
addition to this, a printer cannot reproduce all of the 
colours displayed on a monitor, and vice versa.
> Both devices use very different technologies to represent 
colour. 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 colours such as intense 
reds and blues and these cannot be easily produced on 
any printer using toner or ink. Similarly, there are certain 
colours, (some yellows for exam ple), 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 colours do not match the colours 
displayed on screen.

Viewing conditions 
A print can look very different under different lighting conditions. 
For example, the colours 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  colour settings
The driver settings for manual colour can change the appearance 
of a print. There are several opti ons available to help match the 
printed colours 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 
colour temperature influences how “warm” or “cool” the colours 
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 applic ation displays colour 
Some graphics applications such as Corel Draw or Adobe 
Photoshop may display colour differently from “Office” 
applications such as Microsoft Wo rd. 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 
colour. For example, a printout on recycled paper can look duller 
than one on specially formulated glossy paper.
