If large amounts of toner have scattered
around the characters, the paper might
have high resistivity.Use a different paper, such as high-
quality paper that is intended for color
laser printers.
An image that appears at the top of the
page (in solid black) repeats farther
down the page (in a gray field).Software settings might affect image
printing.In your software program, change the
tone (darkness) of the field in which the
repeated image appears.
In your software program, rotate the
whole page 180° to print the lighter
image first.
The order of images printed might affect
printing.Change the order in which the images
are printed. For example, have the lighter
image at the top of the page, and the
darker image farther down the page.
A power surge might have affected the
device.If the defect occurs later in a print job,
turn the device off for 10 minutes, and
then turn on the device to restart the print
job.

The correct printer driver might not be
selected in the program.Select the correct printer driver.
The device might not be correctly
configured.Print a Configuration page. If no color
appears on the Configuration page,

Media-handling problems
Use the information in this section when the device experiences media-handling problems.
Print-media guidelines
●For best results, make sure that the paper is of good quality, and free of cuts, nicks, tears, spots,
loose particles, dust, wrinkles, voids, staples, and curled or bent edges.
● For best-quality color printing, use a smooth type of paper. Generally, smoother media produces
better results.
● If you are unsure what type of paper you are loading (such as bond or recycled), check the label
on the package of paper.
● Do not use media that is designed for Inkjet printers only. Use media that is designed for color
LaserJet printers.
● 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 device 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
0.2 second).
CAUTION
Failure to follow these guidelines could cause jams or damage to the device.
Solving print-media problems
The following problems with paper cause print quality deviations, jamming, or even damage to the
device.
ProblemCauseSolution
Poor print quality or toner adhesionThe paper is too moist, too rough, too
heavy or too smooth, or it is embossed
or from a faulty paper lot.Verify that the appropriate media type
was selected in the printer driver.
Try another kind of paper, between 100
and 250 Sheffield, 4% to 6% moisture
content.
Dropouts, jamming, or curlThe 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.Verify that the appropriate media type
was selected in the printer driver.
Try printing on media from a new or
different package.
Use long-grain paper.
The paper varies from side-to-side. Turn the paper over.

media in the input tray again. Adjust the
media guides to the width and length of
the media that you are using and try
printing again.
More than one sheet feeds at one time.The media tray might be overloaded.Remove some of the media from the tray.
See Loading trays.
The media might be wrinkled, folded, or
damaged.Verify that the media is not wrinkled,
folded, or damaged. Try printing on

The paper-length adjustment control in
Tray 2 or optional Tray 3 is set at a length
that is greater than the media size.Adjust the paper-length adjustment
control to the correct length.
The pickup roller might be dirty or
damaged. Contact HP Customer Care. SeeHP Customer Care

The document might contain blank
pages.Check the document that you are printing
to see if content appears on all of the
pages.
The device might be malfunctioning.To check the device, print a
Configuration page.
Pages print very slowly.Heavier media types can slow the print
job.Print on a different type of media.
Complex pages will print slowerProper fusing may require a slower print
speed to ensure the best print quality.
Pages did not print. The device might not be pulling mediacorrectly.See Media-handling problems.
The media is jamming in the device.Clear the jam.
The USB cable might be defective or
incorrectly connected.●Disconnect the USB cable at both
ends and reconnect it.
● Try printing a job that has printed in
the past.
● Try using a different USB cable.
Other devices are running on your
computer. The device might not share a USB port.
If you have an external hard drive or
switchbox that is connected to the same
