User Settings on Color/Mono
0
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. If no color content
is detected, it will print the document in monochrome.
The default setting on your machine is “Auto”.
Color
Whether the document contains color or just monochrome, your machine will print the
document using all the colors. This means, for example, that the machine will consume color
toner to print documents comprised solely of black text. If either the Cyan, Magenta or
Yellow toner reaches the end of its life while printing a document in Color mode, the print
job cannot be completed. Users can choose to start the print job again in Mono mode, as
long as black toner is available.
Mono
Select this mode if the document has only black and grayscale text and/or objects. If your
document contains color, selecting Mono mode prints the document in 256 levels of gray.
Note
Users who print primarily black text should select Mono mode to prolong the life of their color
toner cartridges.
Toner Cartridge Life
0
Methods of detecting toner cartridge life
This product detects the life of the toner cartridges using the following two methods:
 Detection by an optical toner sensor
This product has an optical sensor that detects the remaining toner by checking the level
at which toner in a cartridge interrupts light transmitted through windows on either side of
the cartridge. Toner that sticks to the windows or is unevenly distributed in the cartridge
can interfere with the functioning of this sensor, but such interference can often be
resolved by removing, rocking and replacing the cartridge.
 Detection by counting the rotations of the developer roller
This product has a function that will count the rotations of each toner cartridge’s developer
roller and stop the print operation when the upper rotation limit is reached. The upper limit is
set above the number of rotations that would be required for the cartridge to perform
consistently with its advertised page yield. This function is intended to reduce the risk of poor
print quality and damage to the printer. Users who are not printing color documents can “turn
off” this function for their color cartridges by printing in Mono mode (For HL-XXXX, see Printer
Driver in Chapter 2 of the User’s Guide.
For DCP-XXXX/MFC-XXXX, see Basic tab in Chapter 2 of the Software User’s Guide.).
