B LACKS AND GRAYS ( BLACK OVERPRINT )
Black overprint eliminates the white edge between the printed
fonts and the colored background.
Black overprint can only be used when printing 100 percent black
text over a background color.
Black Overprint may not be available with some software
applications.
1. On the [Job Options] tab, click [Advanced].

2. Check [Black Overprint].
NOTES
1. The Black Overprint feature is not included in the
Windows PCL 6 driver.
2. When the background color is very dark, the toner may
not fuse correctly. Change the background to a lighter
color.
