WF-8590 Ink — The Full 748 Ladder, XL on Our Shelf

Epson's compatibility data for the WF-8590 covers the complete 748 ladder: standard packs (black 2,500, colours 1,500 each), XL packs (black 5,000, colours 4,000 each) and XXL packs (black 10,000, colours 7,000 each). We sell the XL tier as compatibles — T748XL120 / T748XL220 / T748XL320 / T748XL420, four individual DURABrite Pro pigment packs, no set, and no standard or XXL compatible in the range.

Two things keep orders for this model right. First, tier is not fitment: standard, XL and XXL all fit this printer, so the code on the pack you remove is a choice, not a lock — XL is simply where our compatible range sits. Second, the neighbouring WF-6530 is the exception elsewhere in the family (no XXL); that restriction does not apply here, but it also does not turn an XL pack into an XXL one.

The same 748XL shelf serves the whole family roster — WF-6090, WF-6530, WF-6590, WF-8090 — so one cartridge list covers every model on it, and a spare bought for any of them fits the rest.

Which 748XL should you buy?

Order colour by colour: black, cyan, magenta and yellow packs are $58.49 each — replace the single pack the printer calls for.
No set exists in this family: our 748 range is four individual XL packs. There is no four-pack set, and no compatible standard or XXL pack, in this range.

Chip, ink and everyday use

Each pack carries a green IC chip that tracks its level, and Epson's own ink pack documents carry the family's standing warning: a firmware update can stop a non-Epson pack that worked before it. Our packs carry new compatible chips; reseat and restart first if a warning ever follows an update. The PrecisionCore print head is fixed in the printer and never leaves it — a replacement is just the sealed pack. Lifetime warranty and 1-year free returns cover every pack.
