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.
