When ink is expended, or the maintenance box and
cassette rollers are at the end of their service life, you need to
replace them. 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
epson.com/recycle for more information.
