Adjusting the Colour Balance
As the printer is used, ambient conditions and the depletion of consumables (the toner cartridge and drum 
cartridge) can gradually cause changes to occur in the four colour components of colour images, cyan, 
magenta, yellow, and black. This results in deviations in the colour balance.
These deviations in the colour balance occur gradually over a long period of time. Ambient conditions 
(temperature and humidity) and the number of times the printer is used can have a large effect on colour 
deviation.
The printer has two colour adjustment functions for the purpose of correcting deviations in the colour bal-
ance. These functions are executed from the key operator programs. For details on using key operator 
programs, see the Key Operator’s Guide. 
When should the colour balance be adjusted?
• It is recommended that colour adjustment be performed once every 500 prints.
• Colour adjustment can also be performed whenever a noticeable change occurs in the colour balance.
• Colour adjustment should always be performed when one of the toner cartridges (cyan, magenta, yellow, 
or black) is replaced.
Colour adjustment functions
The printer has the following two colour adjustment functions:
• Colour Balance settings
This function is used to adjust each of the density levels (low, mid, and high) of the four colour compo-
nents, cyan, magenta, yellow and black. Use this mode when the colour deviation is large.
• Easy calibration
This mode is used for fine adjustment of the grey balance at the mid density level of the colours cyan, 
magenta, and yellow. Use this mode to correct minor colour deviations.
Colour Adjustment Flow Chart 
Use the key operator program on page 3 of the Key Operator’s Guide to 
print a test page
Do the colours on the test page match the colours on the standard 
colour chart included with the printer? (see page 4)

Printing a Test Page and Checking the Colours
Printing a Test Page
Follow these steps to print a test page from the operation panel.
1
Enter the key operator programs.
To enter the key operator programs, see “Using 
the key operator programs” 
on page 3 of the Key 
Operator’s Guide
.
2
Touch the [PRINTER SETTINGS] key.
3
Touch the [COLOUR ADJUSTMENTS] key.
4
Touch the [TEST PRINT] key.
5
Load A4 or letter-size paper in the tray and 
touch the [EXECUTE] key. 
When the [EXECUTE] key is touched, "SELF 
PRINT IN PROGRESS" appears in the display. 
After a brief interval, a colour test page will be 
printed (see below).
Test Page (printed by printer)
The top line of the test page shows the four colours (cyan, magenta, yellow, and black) at low density, mid den-
sity, and high density. The bottom line shows processed grey* at low density, mid density, and high density.
*Processed grey is the colour obtained when the cyan, magenta, and yellow colours on the top line are com-
bined together.

Checking the Colours
The standard colour chart included with the printer is used to check the colours on the printed test page. 
Follow the steps below to check the colours.

Place the colour chart on 
the printed test page as 
shown. Check the density 
of the colours on the test 
page and see if they are 
adjusted to the same level 
as the colours on the 
standard colour 
chart.
If the result of the comparison is that:
• There is a large deviation in the colour densities use the Colour Balance settings 
(see the following page).
• There is a small deviation in the colour densities, use Easy Calibration (see 7 page).
