• The “003” series refers to genuine Epson ink bottles (65 ml) made for EcoTank-style ink-tank printers in Asia. For example: a 003 Black bottle: “Volume – 65 ml, Page Yield – 4,500 pages.”

• There are 4 colour variants: Black (003 Bk), Cyan (003 C), Magenta (003 M), Yellow (003 Y).

• Compatible printer models include (but not limited to) Epson L1110, L3100, L3101, L3110, L3150, L3210, L3250, L5190 etc.

• For instance, a listing in Sri Lanka: “Epson 003 Black Ink Bottle 65ml …

🧐 Key things to check before purchase

• Model compatibility: Make sure your printer model is explicitly listed as being compatible with the 003 series.

• Colour code & volume: Ensure you’re buying the correct colour (Bk, C, M, Y) and correct volume (65 ml).

• Genuine product: Because inks are relatively inexpensive, counterfeit or unofficial products may exist. Check that the packaging looks genuine and the supplier is trustworthy.

• Region code: While the 003 series is intended for Asia region models, many users note that “region code” isn’t always strictly enforced—but compatibility still matters. For example:

  “I bought an ink for my Epson L121 printer. I bought 003, but after searching it should be 664. Is it safe to still use the 003 ink to my printer?”
  So, mixing codes might work—but it’s risky.

• Avoid mixing incompatible ink types: Using a different series (e.g., 664 instead of 003) may physically fit but could affect print quality or printer behavior. Some users report issues with using “wrong” ink.
