For more information, see: • "Clean the print head" on page 139 • "Print a self-test report" on page 131 • "Align the printer" on page 138 Printouts have horizontal streaks or lines Cause: The paper is not feeding properly or is loaded incorrectly. Solution: Make sure the paper is loaded correctly. For more information, see: "Load full-size paper" on page 65 Cause: The copy or print paper type setting is incorrect. Solution: Load high-quality paper in the input tray and print the image with a high print quality setting, such as Best, Maximum dpi, or High Resolution. Always make sure the paper you are printing on is flat. For best results when printing images, use HP Premium Plus Photo Paper. If the problem persists, use the software you installed with the HP All-in-One or another software application to rotate your image 180 degrees so that the light blue, gray, or brown hues in your image do not print at the bottom of the page. For more information, see: "Information on paper" on page 147 Cause: The print head needs to be cleaned. Solution: Clean the print head, and then print a self-test report. Check the color blocks in the report for any problems. If the color blocks show print quality problems, perform a printer alignment. If the problem persists after cleaning and aligning, contact HP support for help.
