Replacing Ink Cartridges and Maintenance Boxes
The maintenance box stores ink that gets flushed from the system during print head cleaning. When an
ink cartridge is expended or the maintenance box is at the end of its service life, you need to replace it.
Note:
The WF-3720/WF-3730 Series do not include a user-replaceable maintenance box.
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 and aligning the print head.
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
for more information.
