SUBLIMAKER Maintenance Box T04D1 for EcoTank ET-15000 ET-4850 — High-capacity Absorbent with Printer Chip

SUBLIMAKER T04D1 maintenance box is a direct replacement waste-ink absorber designed for compatible EcoTank and select Epson printers to capture excess ink and restore proper maintenance functionality.

When an EcoTank or compatible Epson reports a waste-ink or maintenance box alert, replacing the maintenance box prevents overflow warnings and helps the printer continue its head-cleaning routines. The SUBLIMAKER T04D1 (also sold as T04D100/EWMB2/04D1) uses a high-capacity absorbent core inside a reinforced polyethylene housing and includes a replacement kit with a two-headed screwdriver and PE sealing bag for installation and transport.

How does the SUBLIMAKER maintenance box perform and last?

The unit is built with an extra-absorbent sponge and a robust PE structure that holds more waste ink than standard inserts. A stable electronic chip ensures consistent communication with the printer so you get accurate maintenance status reporting until the cartridge is full.

• Super-absorbent core for extended service life before replacement.
• Durable polyethylene shell reduces leakage risk during handling.
• Integrated chip provides reliable printer recognition and status signaling.
