T3661-Compatible Epson Waste Ink Box

This maintenance solution features a rigid ABS enclosure measuring 12.5 x 8.2 x 4.3 cm and weighing 110 g, built for repeated insertion and removal without deformation. Its primary role is to collect surplus ink expelled during printhead maintenance cycles — a process essential for maintaining nozzle health and print clarity. The included remanufactured T3661 unit carries a fully functional chip, allowing real-time communication with the printer’s maintenance counter and enabling accurate tracking of remaining service life. The high-absorption internal structure ensures controlled retention of mixed ink types (cyan, magenta, yellow, black), supporting clean, streak-free output over time. Optimised for users needing dependable, drop-in replacement parts — especially those managing older Epson models still in active service or operating in space-constrained setups where reliability outweighs novelty features.
