• The ink tubes may need to be filled with ink. Flush the ink tubes as instructed below.

  Power Ink Flushing

  If you have not used the product for a long time and see white or dark lines or missing colors in your printouts, even after cleaning the print head several times, you can flush the ink tubes.

  Note: After a Power Ink Flushing, you must turn off the product and wait at least 12 hours before printing again.

  Caution:
  Power Ink Flushing consumes a lot of ink and should be performed only if necessary. Refill the ink tanks before performing a Power Ink Flushing. Power Ink Flushing affects the service life of the ink pads by causing them to reach their capacity sooner. When you see an error message indicating that an ink pad is nearing the end of its service life, the product stops printing and you must contact Epson for support.
