Chapter 14 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. Go to: www.hp.com/support If prompted, choose your country/region, and then click Contact HP for information on calling for technical support. 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 Cause: You are using non-HP ink. Solution: 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 ink. Printer service or repairs required as a result of printer failure or damage attributable to the use of non-HP ink will not be covered under warranty. The text edges are jagged Cause: The font is a custom size. Solution: Some software applications offer custom fonts that have jagged edges when enlarged or printed. Also, if you want to print bitmapped text, it might have jagged edges when enlarged or printed. Use TrueType or OpenType fonts to ensure that the HP All-in-One is able to print smooth fonts. When selecting a font, look for the TrueType or OpenType icon. The printout has a horizontal band of distortion near the bottom of the page Cause: Your image has light blue, gray, or brown hues that print near the bottom of the page. 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. Troubleshooting 166 Troubleshooting
