Smoothness
The degree of smoothness of paper directly affects print quality. If the paper is too rough, the toner does not fuse to the 
paper properly, resulting in poor print quality. If the paper is too smooth, it can cause paper feeding or print quality issues. 
Smoothness needs to be between 100 and 300 Sheffield points; however, smoothness between 150 and 250 Sheffield 
points produces the best print quality.

significantly affect print quality. See Supported print media for information on the preferred weight and for the grain 
direction of print media.
