For more information, see Print-media specifications. 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 Poor print quality or toner adhesion Problem with paper Solution 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 percent moisture content. Dropouts, jamming, curl The paper has been stored improperly.

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 longgrain 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. Use high-quality paper that is made for laser printers. The paper has variations from one side Turn the paper over. to the other.

Open the rear output bin, or use longgrain paper. ● 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 (210° C or 410° F for 0.1 second). CAUTION Failure to follow these guidelines could cause jams or damage to the printer. 104 Chapter 7 Problem solving ENWW

Solving print-media problems

For best results, make sure that the paper is of good quality, and free of cuts, nicks, tears,

spots, loose particles, dust, wrinkles, voids, and curled or bent edges.

For best-quality color printing, use a smooth type of paper. Generally, the smoother the

paper, the better the results, although coated and photo papers are not supported. For more

information, see

Print-media

specifications

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 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 percent

moisture content.

Dropouts, jamming, curl

The paper has been stored improperly.

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 printer

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 has variations from one side

to the other.

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 percent

moisture content.

Open the rear output bin, or use long-

grain paper.

●

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 (210° C or 410° F for 0.1 second).

CAUTION

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