Interpreting the print quality Below are examples of the print results you may see in your test print and the recommended action. If the print quality is satisfactory, you can print on the media without changing printer or heater settings. How do I get the best image quality If you see banding in one color (in the black color in the image above), then there are printhead nozzles out. Print the NOZZLE PRINT/RECOVER pattern and then print your image again to check that the printhead is printing correctly. See How do I... Print the nozzle print pattern. If you see banding in all colors then you need to calibrate the printer for the media you have loaded. If you have selected a preset media type, we recommend that you create a new media type before modifying the settings (See How do I...Manage media types) and then calibrate the printer.
