							Print quality troubleshooting
If you are having problems with print quality, try the solutions in this section and observe 
the following guidelines. 
To troubleshoot print quality issues 
1. Check the print cartridges. 
HP recommends that you use genuine HP print cartridges. Genuine HP print 
cartridges are designed and tested with HP pr inters 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 will not be covered 
under warranty. 
If you believe you purchased genuine HP ink cartridges, go to:
www.hp.com/go/anticounterfeit
For more information, see  “Replace the print cartridges” on page 69. 
2. Check the ink levels. 
If you have installed a refilled or remanufactured print cartridge, or a cartridge that 
has been used in another printer, the ink level indicator will be inaccurate or 
unavailable. The ink levels provided are an  estimate. When print cartridges are truly 
low on ink, printouts will be faded or streaked. As long as print quality is acceptable, 
there is no reason to replace print cartridges. Low ink warnings are provided for 
planning purposes only. 
For more information, see  “Check the estimated ink levels” on page 69. 
3. Make sure you turn off the product by pressing the On button.
CAUTION:Do not turn off the product by turning off a power strip or unplugging 
the power cord from it. If you improperly turn off the product, the print carriage
does not return to the correct position and the print cartridges can dry out.
4. To achieve the best print quality, HP recommends using HP papers that are 
specifically designed for the type of proj ect you are printing along with genuine HP 
ink. HP papers and HP ink are specifically designed to work well together to provide 
high-quality output. 
5. Check the product settings to make sure that the print mode and paper selection is 
correct for the paper and the task. 
For more information, see  “Set the paper type for printing” on page 33 and “Choose
papers for printing and copying” on page 21. 
6. If the cartridges are genuine HP and the product is not in backup mode, print a self- 
test report to determine if the product and ink supplies are operating correctly. 
This will use one sheet of plain paper and a very small amount of ink.
For more information, see  “Print a self-test report” on page 67.

							7.Evaluate the self-test report. 
If the self-test report shows a defect, try the following: 
• Clean the print cartridges automatically. For more information, see  “Clean the
print cartridges” on page 74. 
• If you are missing lines when you print, clean the electrical contacts. For more 
information, see  “Clean the print cartridge contacts” on page 75. 
• Replace the print cartridge. For more information, see  “Replace the print
cartridges” on page 69. 
For more information, see  “Print a self-test report” on page 67. 
8. If the self-test report does not show a problem, investigate other causes, such as the 
image file or software program.

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 different than what you expected. 
For example, the colors in your graphic or photo look one way on your computer 
screen but print out differently, or magenta was replaced with cyan 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: HP recommends using genuine HP print cartridges 
•Solution 2: Check the paper loaded in the input tray
•Solution 3: Check the paper type
•Solution 4: Check to see if the product is in ink-backup mode

							HP recommends that you use genuine HP print cartridges. Genuine HP print 
cartridges are designed and tested with HP pr inters 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 will not be covered 
under warranty. 
If you believe you purchased genuine HP print cartridges, go to:
www.hp.com/go/anticounterfeit
Cause: Non-HP ink was 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 p aper, load the paper with the glossy side down. 
• If the paper is too close to the print cartridge during printing, the ink might be 
smeared. This can happen if the paper is raised, wrinkled, or very thick, such as 
a mailing envelope. Make sure the paper lays flat in the input tray and is not
wrinkled. 
For more information, see: 
•“Load paper” on page 24 
•“Information on paper” on page 93 
Cause: The paper was loaded incorrectly, or it was wrinkled or too thick. 
If this did not solve the issue, try the next solution.
Solution 3: Check the paper type
Solution: HP recommends that you use HP Advanced Papers or any other paper 
type that is appropriate for the product. 
Always make sure the paper you are printing on is flat. For best results when printing 
images, use HP Advanced Photo Paper. 
Store photo 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 will prevent the photo paper from curling.
NOTE: There is no problem with the ink supplies and replacing the print 
cartridges is unnecessary.

							For more information, see: 
•“Recommended papers for printing and copying” on page 22 
•“Information on paper” on page 93 
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 to see if the product is in ink-backup mode 
Solution: Check to see if the the product is printing in ink-backup mode, with only 
one print cartridge installed. 
If the product is in ink-backup mode, text and photo quality will differ from those printed 
when using both print cartridges. 
If you are satisfied with the print quality, continue printing in ink-backup mode. Or, 
replace the missing print cartridge. 
For more information, see:
•“Use ink-backup mode” on page 72 
•“Replace the print cartridges” on page 69 
Cause: A print cartridge was missing and the product was printing in ink-backup 
mode. 
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 product. 
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 product, print
settings, or print cartridges. No further troubleshooting is required.
For more information, see: 
•“Change the print speed or quality” on page 34 
•“Choose papers for printing and copying” on page 21 
Cause: The print settings were set incorrectly.
