The maintenance box stores ink that gets flushed from
the system during printhead cleaning. When an ink cartridge is
expended or the maintenance box is at the end of its service life,
you need to replace it.
You may also need to replace a cartridge that is more
than six months old if your printouts do not look their best, even
after cleaning the printhead.
Note: Please
dispose of your used Epson branded ink cartridges and maintenance
boxes responsibly and in accordance with local requirements.
If you would like to return your used ink
cartridges and maintenance boxes to Epson for proper disposal,
please go to epson.com/recycle for more
information.
Note: When
the maintenance box is full, you cannot print or clean the
printhead until it is replaced. However, you can perform operations
that do not require ink, such as scanning.
