502 vs 522: Which Ink Does Your Printer Use?

This is the most common question we get — and it matters because the two series are not interchangeable.

If your printer uses 502 ink, using 522 ink will cause print quality issues and may damage the print head. Always confirm your ink series before purchasing.

How to Refill Your EcoTank with 502 Ink (Step by Step)

1. Open the scanner unit on top of your printer to expose the ink tanks
2. Open the cap on the ink tank matching the color you are refilling
3. Remove the inner seal from the bottle tip — do not skip this step or ink will not flow
4. Insert the bottle nozzle into the matching port and allow gravity to fill the tank — do not squeeze
5. Watch the tank window and stop when the ink reaches the maximum fill line
6. Replace the tank cap securely and close the scanner unit
7. Run a Nozzle Check from your printer's maintenance or settings menu to confirm the ink is flowing correctly

Common mistake: Squeezing the bottle too hard causes overflow. The 502 pigment ink bottles are designed to drip-fill by gravity — just hold the bottle upright and wait.

Why Pigment Ink Matters for 502 Printers

Unlike dye-based inks (used in the 522 series), pigment-based ink sits on top of the paper rather than soaking in. This gives you:

• Sharper, crisper text — especially noticeable on standard copy paper
• Better water resistance — documents won't smear if they get damp
• Longer archival life — prints last longer without fading

For offices and home users printing primarily documents, forms, and mixed-use pages, pigment ink is the better choice.

Frequently Asked Questions

Is Epson 502 ink the same as 522? No. The 502 series uses pigment-based ink and the 522 series uses dye-based ink. They are designed for different printer models and are not cross-compatible. Using the wrong series will affect print quality and may cause print head issues.

Does this pack include black ink? No. This 3-pack contains Cyan, Magenta, and Yellow only. The compatible black 502 ink bottle (T502120-S) is available separately.

Will these compatible bottles void my Epson printer warranty? Under the Magnuson-Moss Warranty Act, Epson cannot void your printer warranty solely because you used a compatible ink. The law protects your right to choose third-party consumables.

My ink level indicator doesn't update after refilling. Is that normal? Yes. EcoTank printers track ink levels electronically and may not automatically detect a manual refill. You typically need to reset the ink level counter through your printer's Settings or Maintenance menu. Check your printer's user manual for the specific steps — it usually takes under 30 seconds.

How long does one bottle last? At 5% page coverage (a standard text document with moderate content), each 70ml bottle yields approximately 6,000 pages. For comparison, a full-color photo page may count as 40–60% coverage, so heavy photo printing will reduce yield significantly.

What is the shelf life of unopened bottles? 18–24 months when stored in a cool, dry place away from direct sunlight.
