Frequently Asked Questions

How many pages does this yellow print?

Up to 1,100 pages on the ISO/IEC 24711 pattern — Epson's published rating for the T812XL420, the same as every other colour in the XL tier.

Which printers does it fit?

All four officially verified US 812-family models: WF-7310, WF-7820, WF-7840, EC-C7000. Each model takes the same 812 / 812XL code set, confirmed in Epson's own cartridge documentation.

My greens have turned blue and prints look cold. Is yellow the problem?

Very likely. Green is cyan plus yellow; when yellow fades, greens slide blue and warm tones cool down. Run a nozzle check — a broken yellow pattern after cleaning points at the cartridge.

Why does yellow run out when I barely print yellow things?

Two reasons: yellow hides inside most mixed colours (greens, oranges, warm greys, skin tones), and the printer draws a small amount from every cartridge during printing and cleaning to protect the permanent print head — Epson explains this in its own support answers. A "spent" yellow also stops the printer until it is replaced, even for black-only jobs.

Will this cartridge be recognised by my printer?

This cartridge carries a new compatible chip. If your printer's firmware has been updated, recognition issues can occasionally occur — Epson's own guide for these printers states that firmware updates may affect the functionality of third-party ink. Power the printer off, reseat the cartridge until it clicks, and restart before assuming the cartridge is faulty. We do not promise recognition under every future firmware version; if a recognition problem cannot be cleared, the cartridge is covered by our lifetime warranty.

Is there an XXL yellow?

No. The 812 family's XXL tier exists for black only. Yellow, like cyan and magenta, tops out at XL — this cartridge.

What kind of ink is inside?

DURABrite Ultra pigment ink — the same ink family Epson specifies for the whole 812 line, in all four colours. Pigment ink is why these printers are known for smudge-, water- and fade-resistant document prints.

Can I install this XL yellow while the other slots hold standard cartridges?

Yes. Tiers mix freely by position on all four models — Epson lists standard and XL for every slot, and the printer reads each cartridge's own chip.

How do I install it?

Remove the old yellow cartridge, take the new one out of its pack only when you are ready, remove only the protective tape, and do not touch the green chip. Press it into the yellow holder until it clicks, close the cover, and let the printer charge the ink before printing.

How should I store a spare cartridge?

Sealed in its pack, upright, at room temperature and out of direct sunlight. Do not open the pack until install day — the seal is what keeps the cartridge reliable. (A specific shelf-life figure is not published for this product; see Specifications.)

Is this a genuine Epson cartridge?

No — it is a Clever Supplies compatible cartridge built to the genuine cartridge's specification and code, labelled compatible on the box and on this page. It is not manufactured by Epson.

What warranty and returns cover this cartridge?

A lifetime warranty: a cartridge that fails to perform is replaced. Free returns run for the first year. (Returns note: the 1-year returns period is our standing compatible-product policy, applied to inkjet as an assumption pending Emrah's inkjet-specific confirmation.)
