Solve paper-handling problems

The following problems with paper cause print-quality deviations, jamming, or damage to the product.

Problem

Cause

Solution

Poor print quality or toner adhesion

The paper is too moist, too rough, too

heavy or too smooth, is embossed, or

from a faulty paper lot.

Try another kind of paper, between 100

and 250 Sheffield, with 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.

The paper varies from side-to-side.

Turn the paper over.

Jamming, damage to product

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, 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.

Use long-grain paper.

Print is skewed (crooked).

The paper guides might be incorrectly

adjusted.

Remove all paper from the input tray,

straighten the stack, and then load the

paper in the input tray again. Adjust the

paper guides to the width and length of

the paper that you are using and try

printing again.

More than one sheet feeds at one time.

The paper tray might be overloaded.

Remove some of the paper from the tray.

The paper might be wrinkled, folded, or

damaged.

Verify that the paper is not wrinkled,

folded, or damaged. Try printing on

paper from a new or different package.

The product does not pull paper from the

input tray.

The product might be in manual-feed

mode.

At the computer, follow the on-screen

instructions to deactivate manual-feed

mode. Or, at the product, open and close

the print-cartridge door.

The pickup roller might be dirty or

damaged.

Replace the roller. See

Pickup roller

on page

The paper-length adjustment control in

the input tray is set at a length that is

greater than the paper size.

Set the paper-length adjustment control

to the correct length.
