Choose the colors you want to clean. Tip: Use the nozzle check pattern to determine which colors need cleaning. You can save ink by cleaning only selected colors. Cleaning lasts around 2 1/2 minutes. When it's finished, you see a message on the LCD screen. Caution: Never turn off the product during head cleaning or you may damage it. 6. Press 2 to run a nozzle check and confirm that the print head is clean. Note: If you don't see any improvement after cleaning the print head four times, leave the product on and wait at least six hours to let any dried ink soften. Then try cleaning the print head again. If quality does not improve, one of the ink cartridges may need to be replaced. If that doesn't help, contact Epson as described on page 34. If you do not use your product often, it is a good idea to print a few pages at least once a month to maintain good print quality. Cleaning the Print Head 23
