							The printer shuts down unexpectedly
Check the power and power connections
Make sure the printer is connected firmly to a functioning alternating current (AC)
power outlet. For voltage requirements, see 
Electrical specifications.
Alignment fails
If the alignment process fails, make sure you have loaded unused, plain white paper
into the input tray. If you have colored paper loaded in the input tray when you align the
printer, the alignment fails.
If the alignment process fails repeatedly, you may need to clean the printhead, or you
might have a defective sensor. To clean the printhead, see 
Clean the printhead.
If cleaning the printhead does not solve the problem, contact HP support. Go to
www.hp.com/go/customercare. This website provides information and utilities that can
help you correct many common printer problems. If prompted, select your country/
region, and then click  Contact HP for information on calling for technical support.
The printer is not respo nding (nothing prints)
There are print jobs stuck in the print queue
Open the print queue, cancel all documents, and then reboot the computer. Try to print
after the computer reboots. Refer to the Help system for the operating system for more
information.
Check the printer setup
For more information, see 
General troubleshooting tips and resources.
Check the HP software installation
If the printer is turned off when printing, an alert message should appear on your
computer screen; otherwise, the HP software provided with the printer might not be
installed correctly. To resolve this, uninstall the HP software completely, and then
reinstall the HP software.  For more information, see 
Uninstall and reinstall the HP
software.
Check the cable connections
• Make sure both ends of the USB cable or Ethernet cable are secure.
• If the printer is connected to a network, check the following:
 Check the Link light on the back of the printer.
 Make sure you are not using a  phone cord to connect the printer.
Check any personal firewall software installed on the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the firewall might block communication between the computer and
the printer. If there is a problem communicating with the printer, try temporarily
disabling the firewall. If the problem persi sts, the firewall is not the source of the
communication problem. Re-enable the firewall.

							The printer prints slowly
Try the following solutions if the printer is printing very slowly.
•
Solution 1: Use a lower print quality setting
•
Solution 2: Check the ink levels
•
Solution 3: Contact HP support
Solution 1: Use a lower print quality setting Solution: Check the print quality setting.  Best and Maximum dpi  provide the
best quality but are slower than  Normal or Draft . Draft  provides the fastest print
speed.
Cause: The print quality was set to a high setting.
If this did not solve the issue, try the next solution.
Solution 2: Check the ink levels
Solution: Check the estimated ink levels in the ink cartridges.
NOTE:Ink level alerts and indicators provide estimates for planning purposes
only. When you receive a low on ink message, consider having a replacement
cartridge available to avoid possible printing delays. You do not need to replace
the ink cartridges unti l prompted to do so.
NOTE:The printer can operate with one or more depleted cartridges.
However, printing with depleted cartridge s slows the printer and affects the
quality of printed documents. If the black cartridge is depleted, blacks are not as
dark. If a color cartridge is depleted, ou tput is in grayscale. When possible,
replace the depleted cartridge. Do not remove the depleted cartridge until you
have a new ink cartridge available. For information about how to install new
cartridges, see 
Replace the ink cartridges.
CAUTION: Wait until you have a new ink cartridge available before removing
the old ink cartridge. Do not leave the ink cartridge outside of the printer for an
extended period of time. Th is can result in damage to both the printer and the
ink cartridge.
NOTE: While ink cartridges are not damaged when left outside of the printer,
the printhead does need to have all cartridges installed at all times after the
printer is set up and in use. Leaving one or more cartridge slots empty for an
extended period may lead to print quality problems and possibly damage the
printhead. If you have recently left a cartridge out of the printer for an extended
period, or if you have had a recent paper jam, and have noticed poor print
quality, clean the printhead. For more information, see 
Clean the printhead.
For more information, see:
Check the estimated ink levels
Cause: The ink cartridges might have insufficient ink. Printing with depleted
cartridges slows the printer.

							If this did not solve the issue, try the next solution.
Solution 3: Contact HP supportSolution: Contact HP support for service.
Go to: 
www.hp.com/go/customercare. This website provides information and
utilities that can help you correct  many common printer problems.
If prompted, choose your country/region, and then click  Contact HP for information
on calling for technical support.
Cause: There was a problem  with the printer.
The printer is making  some unexpected noises
You might hear some unexpected noises made by  the printer. These are the servicing
sounds when the printer performs automatic servicing functions to maintain the health
of the printhead.
NOTE: To prevent any potential damage to your printer:
Do not turn off the printer while the printer is performing any servicing. If you are
turning off the printer, wait for the printer to come to a complete stop before turning
off using the 
 (Power button). For more information, see Turn the printer off.
Make sure all ink cartridges are inst alled. If any of the ink cartridge is missing, the
printer will perform extra  servicing to protect the printhead.
Blank or partial page printed
Clean the printhead
Complete the printhead cleaning procedure. For more information, see 
Clean the
printhead. The printhead may need to be cleaned if the printer was turned off
incorrectly.
NOTE:Incorrectly turning off the printer can  cause print quality problems like
blank or partial pages. Printhead cleaning  can solve these problems, but turning off
the printer correctly can preven t them in the first place. Always turn the printer off
by pressing the 
 (Power button) on the printer. Wait until the  (Power button)
light goes out before unplugging the power cord or turning off a power strip.
Check the media settings
• Make sure you select the corre ct print quality settings in the printer driver for the
media loaded in the trays.
• Make sure the page settings in the printer driver match the page size of media loaded in the tray.
More than one page is being picked

							There is a blank page in the file
Check the file to make sure there is no blank page.
Something on the page is missing or incorrect
Check the Print Quality Diagnostic page
Print a Print Quality Diagnostic page to help you decide whether to run any
maintenance tools to improve the print quality of your  printouts. For more information,
see 
Print quality troubleshooting.
Check the margin settings
Make sure the margin settings for the document do not exceed the printable area of the
printer. For more information, see 
Set minimum margins.
Check the color print settings
Make sure  Print in Grayscale  is not selected in the printer driver.
Check the printer location  and length of USB cable
High electromagnetic fields  (such as those generated by  USB cables) can sometimes
cause slight distortions to printouts. Move the printer away from the source of the
electromagnetic fields. Also, it is recommended that you use a USB cable that is less
than 3 meters (9.8 feet) long to minimize the effects of these electromagnetic fields.
Placement of the text or  graphics is wrong
Check how the media is loaded
Make sure the media width and length guides fit snugly against the edges of the stack
of media, and make sure the tray is not overloaded. For more information, see 
Load
media.
Check the media size
• Content on a page might be cut off if the document size is larger than the media
that you are using.
• Make sure the media size selected in the printer driver match th e size of media
loaded in the tray.
Check the margin settings
If the text or graphics are cut off at the edges of the page, make sure the margin
settings for the document do not exceed the printable area of your printer. For more
information, see 
Set minimum margins.
Check the page-orientation setting
Make sure the media size and page orientation selected in the application match the
settings in the printer driver.  For more information, see 
Print.

• Load paper with the print side facing down. For example, if you are loading glossy photo paper, load the paper with the glossy side down.
• Make sure the paper lays flat in the input tray and is not wrinkled. If the paper is too close to the printhead during printing, the ink might be smeared. This can
happen if the paper  is raised, wrinkled, or  very thick, such as a mailing
envelope.
For more information, see:
Load media.
Cause: The paper was loaded incorrectly, or it was wrinkled or too thick.

							Solution 4: Check the paper typeSolution: HP recommends that you use HP papers or any other paper type that
is appropriate for the printer.
Always make sure the paper you are pri nting on is flat. For best results when
printing images, use HP Advanced Photo Paper.
Store specialty media in its original packagi ng inside a resealable plastic bag on a
flat surface in a cool, dry place. When you are ready to print, remove only the paper
you plan to use immediately. When you have finished printing, return any unused
photo paper to the plastic bag. This prevents the photo paper from curling.
NOTE: For this issue, there is not a problem with your ink supplies. Therefore,
replacing the ink cartridges is not necessary.
For more information, see:
Select print media
Cause: The wrong kind of paper was loaded in the input tray.
If this did not solve the issue, try the next solution.
Solution 5: Check the print settings Solution: Check the print settings.
• Check the print settings to see if the color settings are incorrect. For example, check to see if the document is set to print in grayscale. Or, check
to see if advanced color settings such as saturation, brightness, or color tone,
are set to modify the  appearance of colors.
• Check the print quality setting and make sure it matches the type of paper loaded in the printer.
You might need to choose a lower print quality setting if colors are running into
each other. Or, choose a higher setting if you are printing a high-quality photo,
and then make sure photo paper such as HP Advanced Photo Paper is loaded
in the input tray.
NOTE: On some computer screens, colors might appear differently than they
do when printed on paper. In this case, there is nothing wrong with the printer,
print settings, or ink cartridges. No further troubleshooting is required.
For more information, see:
Select print media
Cause: The print settings were set incorrectly.
