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 Premium Photo Papers, 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.
