Frequently Asked Questions

What exactly is in the 126 Set of 4 box?

Four individual DURABrite Ultra pigment cartridges: 1 × T126120-S Black, 1 × T126220-S Cyan, 1 × T126320-S Magenta, 1 × T126420-S Yellow — the complete High Capacity tier, matching the contents of Epson's own T126120-BCS 4-pack.

How many pages does the set print?

Per cartridge, not in total: black up to 415 pages; cyan, magenta and yellow up to 440 pages each (ISO/IEC 24711). Cartridges empty at different rates depending on what you print, so we never add the four figures into a single 'set yield'.

Which printers does this set fit?

All 18 models on the 126 list: Stylus NX330/NX430; WorkForce 60, 435, 520, 545, 630, 633, 635, 645, 840, 845; and WorkForce WF-3520, WF-3530, WF-3540, WF-7010, WF-7510, WF-7520.

My NX625 needs ink. Is this its set?

No — the NX625 (and NX530) run 125 Standard + 127 Extra High; 126 cartridges are not part of their specification. The set for those printers is our 127 Set of 4.

When does the set make more sense than singles?

When two or more colors are low together, when reviving a printer that has sat idle, or as the shelf spare for a small office that can't wait on deliveries. If only black is low, a single black is the honest recommendation — sets are for resets, not for forcing a bundle.

Are the cartridges in the set chipped?

Yes — each of the four carries a new compatible chip. This cartridge carries a new compatible chip; if your printer's firmware has been updated, recognition issues can occasionally occur — reseat the cartridge with clean, dry hands (never touch the green chip), restart the printer, and the set should register. Epson's platform notes add that level displays can occasionally read imperfectly with non-original cartridges.

Can I install half the set now and keep the rest?

Yes. Install the colors you need and store the remainder sealed, upright and out of sunlight; open each cartridge only when its turn comes (Epson's platform guidance: use an opened cartridge within about six months).

WorkForce 520 owner here — anything special?

Your printer has two black slots, so a set fills one black position and you'll still want a second black soon after. Most 520 owners pair this set with an extra T126120 single — or step up to the 126 Set of 9, which carries three blacks.

How does this set differ from the 127 Set of 4?

Tier and endurance: 127 cartridges are rated 945 pages black / 755 per color against this set's 415 / 440 — but 127 only fits 14 of these 18 printers (plus the two 127-only NX models). On NX330, NX430, WorkForce 435 and WorkForce 520, this 126 set is the top option that exists.

Are the yields on this page Epson's figures?

Yes — 415 black / 440 per color is Epson's published ISO/IEC 24711 rating for the 126 tier (WorkForce 435 page; the WF-3520-series specification measures 385/470 for the same cartridges). Some compatible sellers advertise much higher 126 numbers; those are not Epson measurements and we don't use them.

Is this a genuine Epson set?

No. It is the Clever Supplies compatible set built to the four 126 cartridge specifications, labeled compatible on the box and this page.

What if one cartridge in the set is faulty?

The lifetime warranty covers each cartridge individually — a single faulty cartridge is replaced on its own; the set doesn't go back as a unit. Free returns apply within the first year. (Returns period note: 1-year returns is our standing compatible-product policy, applied here as an assumption pending Emrah's inkjet-specific confirmation.)
