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,
• 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.
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.

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).
