B LACK OVERPRINT

text over a background colour.
Black Overprint may not be available with some software
applications.
Windows
1. On the [Job Options] tab, click [Advanced].

NOTES:
When the background colour is very dark, the toner may not
fuse correctly. Change the background to a lighter colour.
