							Image defect examples
This section provides information about identifying and correcting print defects.
NOTE:If these steps do not correct the problem, contact an HP-authorized dealer or service
representative.
Light print or faded
● The print cartridge is nearing end of life.
● Redistribute the toner to extend the life.
● The media might not meet Hewlett-Packards media
specifications (for example, the media is too moist or too
rough).
● If the whole page is light, the print density adjustment is
too light or EconoMode might be turned on. Adjust the
print density, and disable EconoMode in the printer
Properties.
Toner specks
●The media might not meet Hewlett-Packards media
specifications (for example, the media is too moist or too
rough).
● The printer might need to be cleaned.
● The print cartridge might be defective.
Dropouts
●A single sheet of media might be defective. Try reprinting
the job.
● The media moisture content is uneven or the media has
moist spots on its surface. Try printing with new media.
● The media lot is bad. The manufacturing processes can
cause some areas to reject toner. Try a different type or
brand of media.
● The print cartridge might be defective.

							Vertical lines
The photosensitive drum inside the print cartridge has probably
been scratched. Install a new HP print cartridge.
Gray background
●Change the media to a lighter basis weight.
● Check the printers environment. Very dry (low humidity)
conditions can increase the amount of background
shading.
● The density setting might be too high. Adjust the density
setting.
● Install a new HP print cartridge.
Toner smear
●If toner smears appear on the leading edge of the media,
the media guides might be dirty. Wipe the media guides
with a dry, lint-free cloth.
● Check the media type and quality.
● The fuser temperature might be too low. In your printer
driver, make sure the appropriate media type is selected.
● Try installing a new HP print cartridge.
Loose toner
●
The fuser temperature might be too low. In your printer
driver, make sure the appropriate media type is selected.
● Clean the inside of the printer.
● Check the media type and quality.
● In your printer driver, make sure the appropriate media
type is selected.
● Plug the printer directly into an AC outlet instead of into a
power strip.

							Vertical repetitive defects
●The print cartridge might be damaged. If a repetitive mark
occurs at the same spot on the page, install a new
HP print cartridge.
● The internal parts might have toner on them. If the defects
occur on the back of the page, the problem will probably
correct itself after a few more printed pages.
● In your printer driver, make sure the appropriate media
type is selected.
Misformed characters
●If characters are improperly formed, producing hollow
images, the media stock might be too slick. Try a different
media.
● If characters are improperly formed, producing a wavy
effect, the printer might need service. Print a configuration
page. If the characters are improperly formed, contact an
HP-authorized dealer or service representative.
Page skew
●Make sure that the media is loaded correctly and the
media guides are not too tight or too loose against the
media stack.
● The input bin might be too full.
● Check the media type and quality.

							Curl or wave
●Check the media type and quality. Both high temperature
and high humidity cause media to curl.
● The media might have been in the input tray too long.
Turn over the stack of media in the tray. Also, try rotating
the media 180° in the input tray.
● Open the straight-through output door and try printing
straight through.
● The fuser temperature might be too high. In your printer
driver, make sure the appropriate media type is selected.
If the problem persists, select a media type that uses a
lower fuser temperature, such as transparencies or light
media.
Wrinkles or creases
●Make sure that media is loaded properly.
● Check the media type and quality.
● Open the straight-through output door and try printing
straight through.
● Turn over the stack of media in the tray. Also, try rotating
the media 180° in the input tray.
● For envelopes, this can be c
aused by air pockets inside
the envelope. Remove the envelope, flatten the
envelope, and try printing again.
Toner scatter outline
● If large amounts of toner have scattered around the
characters, the media might be resisting the toner. (A
small amount of toner scatter is normal for laser printing.)
Try a different media type.
● Turn over the stack of media in the tray.
● Use media that is designed for laser printers.
