How do I perform maintenance on the ET-2800 print head?

The ET-2800 offers three maintenance options: nozzle check, print head cleaning, and power cleaning. To perform a nozzle check from the control panel, go to Settings > Printer Setup > Maintenance > Nozzle Check, then press the start button to print a test pattern. For print head cleaning, select Cleaning from the Maintenance menu. For more thorough cleaning, use Power Cleaning. These can also be done using computer utilities. Run nozzle checks regularly to maintain print quality.
