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.

For a complete list of supported media, see Supported sizes of print media.

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	The paper is too moist, too
adhesion	rough, too heavy, too smooth,
	or it is embossed or from a
	faulty paper lot.
Dropouts, jamming, curl	The paper has been stored
	improperly.
	The paper varies from side to
	side.
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.

Try another kind of paper, between 100 and 250 Sheffield, and with 4 to 6% moisture content.

Store paper flat in its moisture- proof wrapping.

Turn the paper over.

Open the rear output bin, or use long-grain paper.

Turn the paper over.

Jamming, damage to printer	The paper has 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,

NOTE

CAUTION

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).

Failure to follow these guidelines could cause jams or damage to the printer.
