The maintenance box is a component in many Epson inkjet / ink-tank printers that collects excess ink — ink that the printer flushes out during tasks like printhead cleaning, nozzle checks, priming, and borderless printing.

Inside it are absorbent pads or a sponge‐like material which soak up this waste ink so that it doesn’t leak onto internal printer components.

The printer monitors how full the absorption capacity is. When the box nears its limit, the printer will display warnings like “Maintenance box nearing end of service life” or “Maintenance box full."

Once it reaches capacity, the printer will stop printing/doing ink operations, to prevent ink overflow and damage.
