You can change the black finish when printing in color. The black finish setting can be used when [Office Color] or [Graphic Pro] is selected in the printer driver.
There are two types of black finish: composite black (made from CMYK toner) and true black (made from black toner only).
There are two types of black finishes; one is composed of cyan (C), magenta (M), yellow (Y) and black (K) toners, and the other is composed of a black (K) toner only. A black finish using CMYK toners is suitable for printing photographs. A black finish using a black toner only is suitable for printing black text or graphics.
If you use the [Office Color] function, you can also select the auto. If Automatic is selected, the suitable method is selected automatically to print out the document.
For the Windows XPS printer driver, follow the steps for the Windows PS printer driver and select [Color Mode] in the [Color] tab, and then select the method to create black from [Black Finish].
