Osinkjet OS-T04D1 Maintenance Box for Select Epson EcoTank and WorkForce Printers

Replacing a worn maintenance box helps keep a compatible Epson printer ready for continued use. The Osinkjet OS-T04D1 is a replacement part for select EcoTank, WorkForce, and Expression Home models, giving you a targeted option when your printer calls for a T04D1-style box.

The package includes one maintenance box, a two-head screwdriver, and a PE seal bag. Customers often describe the part as easy to install and a good fit, feedback on how long it lasts is mixed, so experiences vary.

The essentials

This compatible T04D1 maintenance box is made for specific Epson inkjet printers. Its value is in addressing a maintenance-box replacement directly, rather than buying ink cartridges or other supplies that serve a different purpose. The listed dimensions are 2.5" deep by 2.49" wide by 2.5" high, useful details when identifying the part for your printer.

The box is identified as compatible with a range of Epson EcoTank models, including ET-15000, ET-3700, ET-3710, ET-3750, ET-3760, ET-3830, ET-3843, ET-3850, ET-4750, ET-4760, ET-4850, ET-5150, ET-5170, ET-5180, ET-M1170, ET-M2170, and ET-M3170. Listed WorkForce models include ST-3000, ST-4000, ST-C4100, ST-M1000, ST-M3000, WF-2860, and WF-2960. It is also listed for Expression Home XP-5100 and XP-5200. Is your printer one of these models? Matching the full model number is the practical first step to choosing the right replacement.

Who it’s for

This replacement is intended for owners of the listed Epson printers who need a T04D1 maintenance box. It suits a focused repair or maintenance purchase: the part replaces the maintenance box, while ink cartridges remain a separate type of printer supply. Check your printer’s exact model against the compatibility list before ordering, especially if its model number is similar to one shown here.

Getting the most from it

Use the printer’s maintenance-box replacement procedure and the included two-head screwdriver as appropriate for the installation. The package also contains a PE seal bag. Customers commonly mention straightforward installation and a good fit, including for the ET-3750, though individual experiences with durability differ. Treat those comments as buyer feedback rather than a guarantee of service life.

For a smooth match, identify the printer model from its label or settings and compare it with the list above. This helps keep the replacement focused on the maintenance part your printer uses instead of relying on a broad search for general printer supplies.
