box is at the end of its service life, you need to replace it. The
maintenance box stores ink that gets flushed from the system during
print head cleaning.
dispose of your used Epson branded ink packs and maintenance boxes
responsibly and in accordance with local requirements. If you would like to return your used ink packs and
maintenance boxes to Epson for proper disposal, please go to
