When an ink cartridge is expended, you need to replace
it.
You may also need to replace a cartridge that is more
than six months old, or if your printouts do not look their best,
even after cleaning and aligning the print head.
Note: Please
dispose of your used Epson branded ink cartridges responsibly and
in accordance with local requirements. If you would like to return
your used ink cartridges to Epson for proper disposal, please go to
epson.com/recycle for more information.
