Maintain the HP All-in-One Figure 12-15 Color bars - color mixing (yellow bar contains magenta streaks) NOTE: If cleaning the printhead does not solve this print quality issue, contact HP support for service. If you do not see any defects on the print quality report, then the printing system is working correctly. There is no reason to replace supplies or have the product serviced, because they are functioning properly. If you still have a print quality problem, here are some other things you can check: • Check the paper. • Check the print settings. • Make sure your image has sufficient resolution. • If the problem seems confined to a band near the edge of your printout, use the software you installed with the product or another software application to rotate the image 180 degrees. The problem might not appear on the other end of the print.
