Guidelines for using paper
For best results, make sure the paper is of good quality, and free of cuts, nicks, tears, spots,
loose particles, dust, wrinkles, voids, and curled or bent edges.
If you are unsure what type of paper you are loading (such as bond or recycled), check the
label on the package of paper.

The following problems with paper cause print quality deviations, jamming, or even damage
to the printer.
Symptom Problem with paper Solution
Poor print quality or toner
adhesion The paper is too moist, too
rough, too heavy, too smooth,
or it is embossed or from a
faulty paper lot. Try another kind of paper,
between 100 and 250
Sheffield, and with 4 to 6%
moisture content.
Dropouts, jamming, curl The paper has been stored
improperly.
The paper varies from side to
side.
Store paper flat in its moisture-
proof wrapping.
Turn the paper over.
Excessive curl The paper is too moist, has the
wrong grain direction, or is of
short-grain construction.
The paper varies from side to
side.
Open the rear output bin, or
use long-grain paper.
Turn the paper over.
Jamming, damage to printer The paper has cutouts or
perforations. Use paper that is free of
cutouts or perforations.
Problems with feeding The paper has ragged edges,
or it is from a faulty paper lot.
The paper varies from side to
side.
The paper is too moist, too
rough, too heavy, or too smooth.
It has the wrong grain direction,
is of short-grain construction, or
it is embossed.
Use high-quality paper that is
made for laser printers.
Turn the paper over.
Try another kind of paper,
between 100 and 250
Sheffield, and with 4 to 6%
moisture content.
Open the rear output bin, or
use long-grain paper.
NOTE Do not use letterhead paper that is printed with low-temperature inks, such as those used in
some types of thermography. Do not use raised or embossed letterhead. The printer uses
heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted
forms use inks that are compatible with this fusing temperature (200°C or 392°F for
0.1 second).
CAUTION Failure to follow these guidelines could cause jams or damage to the printer.
