Epson 502 vs 522 Ink: Do Not Mix Bottle Families
Compare Epson 502 and 522 ink bottle families and learn why model and region verification matters.
The short answer
502 and 522 identify different Epson ink families. Match the number, color, printer model and market before opening a bottle; a similar-looking bottle is not enough.
Before you start
- Check the tank lid or manual.
- Match color and bottle family.
- Verify region-specific model support.
Find the number before you shop
Look in the exact model’s official ink-supply list, then compare it with the label on the bottle. Use the tank lid or existing bottle as a cross-check, not the only source when the printer’s history is unknown.
Check the whole set
A multi-bottle listing can contain colors or quantities you do not need. Read the contents and individual bottle numbers rather than relying on a photo of a familiar printer.
If the wrong ink has already been added
Stop printing and contact Epson with the printer model and both ink numbers. Do not try to drain, dilute or flush the tank using a generic online procedure.
Ink bottle decision
| Bottle family | Use it when | Avoid when |
|---|---|---|
| 502 | Your exact EcoTank model lists 502 | Your model label lists 522 or another family |
| 522 | Your exact EcoTank model lists 522 | You are trying to use it as a 502 substitute |
Worth avoiding
- Do not mix 502 and 522 unless Epson specifically lists both for your exact model.
