Note: After running a Power Cleaning, you must turn off the product and wait at least 12 hours before running another Power Cleaning. Power Cleaning Using a Computer Utility You can run a Power Cleaning using a utility on your Windows or Mac computer. When an ink pad reaches the end of its service life, the product stops printing and you must contact Epson for support. Power Cleaning may cause the ink pads to reach their capacity sooner. Make sure each ink tank is at least one-third full before running a Power Cleaning, or it may damage the product. Running a Power Cleaning consumes a lot of ink, so you should run it only if necessary. If you do not see improvement after running a Power Cleaning, turn off the product and wait at least 12 hours before running another Power Cleaning.
If you still see white or dark lines or missing nozzles in your printouts, even after cleaning the print head several times, you can run a Power Cleaning.
I cleaned the print head three times, but my printout still has white or dark lines running through it.
