WF-3733 Ink — The Retail Twin on the Same 702 Shelf
The WF-3733 is the retail variant of the WF-3730, and Epson's own datasheets list its compatibility exactly as 'WF-3720, WF-3730 and WF-3733' — one cartridge family, three machines. The codes are the family's standard set: standard T702120 / T702220 / T702320 / T702420 and high-capacity T702XL120 black and T702XL220 / T702XL320 / T702XL420 colours. Our products are the XL half of that roster — up to 1,100 pages for black, up to 950 per colour (ISO/IEC 24711) — because the compatible ladder for this family is built on XL.
Nothing on this page fits any 802 printer, and the European WF-3725DWF is a different, region-coded model that is not part of the US list. If your badge says WF-3733, every cartridge here is yours.
The same 702XL shelf serves the whole family roster — WF-3720, WF-3730 — so one cartridge list covers every model on it, and a spare bought for any of them fits the rest. Pigment ink is the everyday half of this family's story: dry-to-the-touch pages and smudge-resistant text, with spares that keep best sealed — away from air and light — until the day they are installed.
Which 702XL should you buy?
- One colour ran out: replace just that slot — black is $22.49; cyan, magenta and yellow are $16.49 each.
- Full refresh: the Set of 4 ($64.44) replaces all four positions in one box.
- Stocked office shelf: the Set of 9 ($133.38) carries three blacks and two of each colour, all XL.
Chip, ink and everyday use
Because the WF-3733 shares the WF-3730's platform, it shares the family's firmware caution too: a chip is included, and printer firmware updates can affect recognition of compatible cartridges on this platform. Install with the printer's automatic updates paused, reseat and restart if a warning appears, and know that our lifetime warranty — with 1-year free returns — covers a cartridge that will not clear it.
