How do I run a nozzle check to see if the print head needs cleaning?

You can check the print head nozzles using either the product control panel or a computer utility, as described in the Print Head Nozzle Check section. Navigate to the Adjusting Print Quality section and follow the steps for Checking the Nozzles Using the Product Control Panel or Checking the Nozzles Using a Computer Utility. If the nozzle check shows gaps or faint areas, you should proceed with a print head cleaning. (Page 158-163)
