The maintenance box, sometimes called a waste ink tank, collects excess ink expelled from the printhead during routine cleaning cycles.

When the maintenance box reaches the end of its service life, the printer will display a warning indicating that replacement is required. Printing may stop until the maintenance box is replaced.

This is a normal part of printer maintenance. The maintenance box is user-replaceable and can generally be changed in just a few minutes without tools.
