Important information for the toner cartridge life
A
Color/Mono setting in the printer driver
A
Users can change the Color/Mono settings on the printer driver as follows:
Auto
The machine checks the content of the document for color. If color is detected anywhere in the document,
it will print the whole of the document using all the colors. 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 color content is detected, it will print the document in monochrome.
The default setting on your machine is Auto.
NOTE
The machine’s color sensor is very sensitive and may perceive faded black text or an off-white background
as color. If you know that your document is black and white and you want to conserve color toner, select
Mono mode.
Color
Whether the document contains color or just monochrome, your machine will print the document using all
the colors.
Mono
Select this mode if the document has only black and grayscale text and/or objects. If your document
contains color, this mode prints the document in 256 levels of gray using the black toner.
NOTE
If either the Cyan, Magenta or Yellow toner reaches the end of its life while printing a color 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.
For more information about the settings in the printer driver, see Chapter 2: Driver and Software.
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 color that are necessary to create an image
Detection by counting the rotations of the developer roller
This product counts the dots of each color 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 (for more information on page yield, please visit
). 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.
