This section explains how to select the "Color Mode" on the [Color] tab of the printer driver properties window. The 
following three selections are available for the "Color Mode".
Automatic:

The machine automatically determines whether each page is colour or black and white and prints the 
page accordingly. Pages with colours other than black and white are printed using Y (Yellow), M 
(Magenta), C (Cyan) and Bk (Black) toner. Pages that are only black and white are printed using Bk 
(Black) toner only. This is convenient when printing a document that has both colour and black and 
white pages, however, the printing speed is slower.

Color:

All pages are printed in colour. Both colour data and black and white data are printed using Y (Yellow), 
M (Magenta), C (Cyan) and Bk (Black) toner.

Black and White: All pages are printed in black and white. Colour data such as images or materials for a presentation 

are printed using black toner only. This mode helps conserve colour toner when you do not need to 
print in colour, such as when proofreading or checking the layout of a document.

When "Color Mode" is set to [Automatic] on the [Color] tab of the printer driver
Even if the print result is black and white, the following types of print jobs will be counted as 4-colour (Y (Yellow), M 
(Magenta), C (Cyan), and Bk (Black)) print jobs. To be always counted as a black and white job, select [Black and White].

• When the data is created as colour data.
• When the application treats the data as colour data even though the data is black and white.
• When an image is hidden under a black and white image.

The button that is used to open the printer driver properties window (usually [Properties] or [Printing Preferences]) 
may vary depending on the software application.
