Epson printers are designed with an internal maintenance box or absorbent pads that soak up excess ink used during print head cleanings. The printer's firmware keeps a strict count of how many pages have been printed and how many cleaning cycles have been run. Once this waste ink counter reaches a pre-set limit—often long before the physical pads are full—the printer intentionally locks itself down to prevent potential ink overflow and internal damage.
