How do I clean the print head on the ET-2800?

You can clean the print head from the product control panel by pressing the home button, selecting Settings > Printer Setup > Maintenance > Print Head Cleaning, and following the instructions. Alternatively, use a computer utility to perform print head cleaning. For stubborn clogs, you may need to run Power Cleaning, which uses more ink but provides a deeper clean. Do not attempt to manually clean the print head.
