How do I perform a print head nozzle check on the ET-2800?

You can perform a nozzle check using your product's control panel or a computer utility. Using the control panel, press the home button, navigate to Settings, select Printer Setup, and find the Print Head Nozzle Check option. The product will print a nozzle check pattern. Examine it to see if any colors are missing or have lines. If problems are detected, you can proceed to clean the print head using the same menu.
