Important information for the toner cartridge life
A
Colour/Mono setting in the printer driver
A
Users can change the Colour/Mono settings on the printer driver as follows:
Auto
The machine checks the content of the document for colour. If colour is detected anywhere in the
document, it will print the whole of the document using all the colours. In other words, it will mix some of
the toners to help achieve every shade detected in the document, increasing the density of toner applied
to the page. If no colour content is detected, it will print the document in monochrome.
The default setting on your machine is
Auto
.
NOTE
The machine’s colour sensor is very sensitive and may perceive faded black text or an off-white
background as colour. If you know that your document is black and white and you want to conserve colour
toner, select
Mono
mode.
Colour
Whether the document contains colour or just monochrome, your machine will print the document using
all the colours.
Mono
Select this mode if the document has only black and greyscale text and/or objects. If your document
contains colour, this mode prints the document in 256 levels of grey using the black toner.
NOTE
If either the Cyan, Magenta or Yellow toner reaches the end of its life while printing a colour document, the
print job cannot be completed. You can cancel your print job and choose to start the print job again in
Mono
mode, as long as Black toner is available.

Toner Cartridge Life
A
This product detects the life of the toner cartridges using the following two methods:
Detection by counting the dots of each colour that are necessary to create an image
Detection by counting the rotations of the developer roller
This product counts the dots of each colour used to print every document and the rotations of each toner
cartridge’s developer roller. The print operation will stop when either one of the upper limits are reached.
The upper limit is set above the number of dots or rotations required for the cartridge to perform
consistently with its advertised page yield. This feature is intended to reduce the risk of poor print quality
and damage to the machine.
There are two messages that indicate when the toner nears or reaches its life end:
Toner Low
and
Replace Toner
.
