How do I clean the print head on my ET-2800 if my prints have gaps or lines?

You can clean the print head using the product control panel by navigating to the print head cleaning option, or by using a computer utility on Windows or Mac. The manual also covers Power Cleaning, which is a more intensive cleaning option for persistent print quality issues. It is recommended to first run a nozzle check to confirm whether cleaning is needed. (Page 164-173)
