How do I clean the print head on the ET-3850 if my prints look faded or have gaps?

You can clean the print head using the product control panel by navigating to the head cleaning option, or by using a computer utility on Windows or Mac. If standard cleaning does not resolve the issue, a Power Cleaning option is also available through the control panel or computer utility. It is recommended to run a nozzle check first to confirm the print head needs cleaning. (Page 187-195)
