Frequently Asked Questions

How many pages does the T279XL420 print?

Up to 740 pages, Epson's published rating for the genuine cartridge on the ISO/IEC 24711 pattern. Warm-toned photo work leans on yellow heavily, so photo printers may see less; mixed use tracks the rating.

Which printer does it fit?

Only the Expression Photo XP-980 — the sole 279 printer. The XP-960 belongs to the 277 family and takes none of these cartridges.

Does it have a chip?

Yes — a new compatible chip that reports ink levels. This cartridge carries a new compatible chip. If your printer's firmware has been updated, recognition issues can occasionally occur; reseating the cartridge and restarting usually clears a false warning.

What ink is inside?

Claria Photo HD dye ink. The whole 279 family is dye-based — that is what gives the XP-980 its photo color range and gloss.

Is this standard or high capacity?

High capacity — the XL, rated 740 pages against the standard T279420's 360. The compatible ladder for the 279 family is XL-only, and we say so on the box.

My printer says the cartridge is not recognized. What now?

Power the printer off, remove the cartridge, check the chip contacts are clean and dry, reseat it until it clicks, and power back on. If a recent firmware update preceded the message, that is the likely trigger — contact us and we will work through it under the lifetime warranty.

Can I replace just the yellow?

Yes. Each of the six slots is independent; replace colors one at a time as they empty, mixing XL and standard tiers freely.

How much ink is in it, in millilitres?

We don't publish a figure: Epson's US documentation does not state a millilitre volume for this family, so the Volume field is left blank rather than filled with a reseller's claim. The comparable, verifiable figure is the 740-page ISO yield.

Is it a genuine Epson cartridge?

No — it is a Clever Supplies compatible built to the T279XL420-S specification and labeled compatible on the box and this page. It is not manufactured by Epson.

Why do all five colors share the same 740 rating?

That is Epson's own summary for the XL tier: black 500, color 740 — one color figure for all five. Real consumption still differs by what you print; the rating is a common measuring stick, not a per-color promise.

What does the lifetime warranty cover?

A cartridge that fails to perform — not recognized after troubleshooting, leaking, or printing poorly from new — is replaced under the lifetime warranty. Free returns apply within the first year.

Should I buy the single or a set?

The single if only yellow is low. If colors are close behind, the Set of 6 (all XL) or the Set of 13 bulk pack works out cheaper per cartridge — both are linked from this page.
