Epson EcoTank Ink Maintenance Box T04D1 for ET-3700, XP-5100

The Epson T04D100 is an ink maintenance box that collects the extra ink your EcoTank or Expression printer flushes out during routine head cleanings. By safely holding this waste ink, it prevents internal overflow, keeps the print path clean, and helps every nozzle stay ready for the next job.

When the box reaches capacity, the printer shows an on screen alert and pauses printing until the part is replaced. Swapping it takes only a moment: slide the old unit out of its bay, click the new one in, and you are ready to print again. No tools, special skills, or extended downtime are required, which is ideal for a busy home office or a small workgroup.

This genuine Epson component works with the EcoTank ET-3700 and WorkForce ET-3750 as well as the Expression Home XP-5100. Using the correct maintenance box protects your warranty and ensures that every drop of ink you buy is used for pages rather than cleanup.

If you print lesson plans, invoices, photos, or long reports, keeping a spare T04D100 on hand is an easy way to avoid delays. At about 0.4 lbs, the box is light enough to store in a desk drawer, so it is always within reach when the printer calls for it.
