The Epson ColorWorks C4000 Waste/Maintenance Box (C33S021601) is a genuine Epson consumable designed to keep your C4000 series printer running as it should. It collects excess ink produced during printing and maintenance cycles — the kind of unglamorous but necessary work that keeps your output clean and your print heads clear.

Skipping or delaying replacement is one of the more reliable ways to introduce quality issues into an otherwise well-managed print operation. Regular swaps are straightforward and take minutes, making this a low-effort way to protect a printer you depend on.

As a genuine Epson part, it's built to the exact tolerances of the C4000 series — not an approximation of them. If you're running a label printing operation where consistency matters, this is simply part of the maintenance routine.
