							Wrong, inaccurate, or bleeding colors
If your printout has one of the following print quality problems, try the solutions in this
section for help.
• Colors look wrong
For example, green was replaced with blue in your printout.
• Colors run into each other, or look like they are smeared on the page. The edges
might have a feathering appearance instead of being sharp and defined.
Try the following solutions if the colors appear wrong, inaccurate, or bleed into each other.
•
Solution 1: Make sure you are using genuine HP ink cartridges
•
Solution 2: Check the paper loaded in the input tray
•
Solution 3: Check the paper type
•
Solution 4: Check the ink levels
•
Solution 5: Check the print settings

Solution 6: Align the printhead

Solution 8: Contact HP support
Solution 1: Make sure you are using genuine HP ink cartridges
Solution:Check to see if your ink cartridges are genuine HP ink cartridges.
HP recommends that you use genuine HP ink cartridges. Genuine HP ink cartridges
are designed and tested with HP printers to help you easily produce great results,
time after time.
NOTE:HP cannot guarantee the quality or reliability of non-HP supplies. Printer
service or repairs required as a result of using a non-HP supply are not covered
under warranty.
If you believe you purchased genuine HP ink cartridges, go to:
www.hp.com/go/anticounterfeit
Cause:Non-HP ink cartridges were being used.
If this did not solve the issue, try the next solution.
Solution 2: Check the paper loaded in the input tray
Solution:Make sure the paper is loaded correctly and that it is not wrinkled or too
thick.
• Load paper with the side you want to print on 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 3: Check the paper type
Solution: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 printing on is flat. For best results when printing
images, use HP Advanced Photo Paper.
Store specialty media in its original packaging 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 or printhead 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 4: 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-ink alert, consider having a replacement cartridge
available to avoid possible printing delays. You do not need to replace the ink
cartridges until print quality becomes unacceptable.
For more information, see:
Check the estimated ink levels
Cause:The ink cartridges might have insufficient ink.
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.
If this did not solve the issue, try the next solution.
Solution 6: Align the printhead

Solution:Check the following potential problems, and then clean the printhead.
• Check the orange pull tab on the ink cartridges. Make sure they were completely
removed.
