How do I check and refill the ink levels in my ET-2800?

You can check ink levels directly on the product by going to the control panel or through your computer software. To check on the product, press the home button and navigate to the appropriate menu. On Windows, use the Epson software utility to check ink levels; on Mac, use the printer utility. When ink is low, purchase genuine Epson ink bottles (part numbers available in the manual) and refill the ink tanks following the refilling instructions provided in the manual.
