If your Epson Expression Premium photo printer is showing maintenance warnings or error lights, you probably need to replace the maintenance box (also called waste ink absorber or pad).

This Aomya T366 (also called T366100 or T3661) is compatible with many Epson models: XP-15000, XP-6000, XP-6100, XP-970, XP-8500, XP-8600, XP-8700, and several others (check the list!).

It's the equivalent to the Epson E3661 part.

Comes with a chip that lets your printer recognize it properly.

Inside is a high-quality sponge pad that absorbs the waste ink from cleaning cycles.

When your printer's internal pad gets saturated, it needs replacing to prevent ink overflow and potential damage.

Installation is usually straightforward - consult your printer manual for location (often in the back or bottom).

This aftermarket part costs way less than buying from Epson directly.

Every unit is inspected before shipping.

Keep your printer running smoothly and avoid costly service calls.

Important: This is NOT an ink cartridge - it's the maintenance component that handles waste ink.

If you print a lot of photos, you might need to replace this every couple of years.

Good to have on hand!
