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.
Use long-grain paper, or use the Less paper curl setting. See
Reducing paper curl on page 100.
The paper varies from side-to-side. Turn the paper over.
Jamming, damage to
device
The paper has cutouts or perforations. Use paper that is free of cutouts or perforations.
