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.
Jamming, damage to paper
The paper has cutouts or perforations.
Use paper that is free of cutouts or
perforations.
Problems with feeding
The paper has ragged edges.
Use high-quality paper that is made for laser
printers.
The paper varies from side-to-side.
Turn the paper over.
The paper is too moist, too rough, too heavy
or too smooth, has the wrong grain direction,
or is of short-grain construction 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.
Open the rear output bin, or use long-grain
paper.

The media guides might be incorrectly
adjusted.
Remove all media from the input tray,
straighten the stack, and then load the
