Media-handling problems
Problem Cause Solution
Poor print quality or toner adhesion The paper is too moist, too rough, too
heavy or too smooth, or it is embossed
or from a faulty paper lot.
Try another kind of paper, between 100
and 250 Sheffield, 4 to 6% moisture
content.
Dropouts, jamming, or curl The paper has been stored incorrectly. Store paper flat in its moisture-proof
wrapping.
The paper has variability from one side
to the other.
Turn the paper over.
Excessive curl The paper is too moist, has the wrong
grain direction, or is of short-grain
construction
Open the rear output bin, or use long-
grain paper.
The paper varies from side-to-side. Turn the paper over.
