MFC-J5945DW

MFC-J5945DW Ink — The Large Platform, and the Identical-Yield Trap

Brother’s official list for the LC3037/LC3039 family names exactly seven printers, and the MFC-J5945DW is one of them. The MFC-J5945DW is one of the two models in Brother’s official Supply Specifications for this platform, where the LC3037 and LC3039 ratings are printed side by side. Both tiers fit this machine and mix freely by slot: LC3037 Super High Yield (3,000 pages black / 1,500 per color) below LC3039 Ultra High Yield (6,000 black / 5,000 per color), rated in accordance with ISO/IEC 24711.

The MFC-J5945DW is one of the two models whose Supply Specifications print the LC3037 and LC3039 ratings side by side — and identical ratings elsewhere are exactly its trap. The small INKvestment printers (MFC-J805DW, MFC-J995DW and their siblings) post the same yield figures, 3,000/1,500 and 6,000/5,000, but take LC3033/LC3035 cartridges with different bodies that will not install here, just as LC3037/LC3039 cartridges will not install in them. Buy by cartridge family and model list, never by yield figure alone. Similar-looking LC3017/LC3019 and LC3029 cartridges do not fit either — and the newer MFC-J5855DW-generation machines take LC406, not LC3039.

Set the side-by-side ratings against your own printing rhythm and the choice makes itself. An LC3039 color cartridge carries more than three times the fill of its LC3037 counterpart — 5,000 pages against 1,500 — while the black carries twice as much, 6,000 against 3,000. A machine in daily service gets the long run out of the Ultra tier; a lightly used one can stay on the Super High tier, which covers the same slots at the lower fill.

Which LC3039 should you buy?

• The shelf for this printer: the LC3039 Set of 4 ($89.94) — one of each color, each cartridge chipped, at 6,000 black / 5,000 per color.
• Singles: LC3037 single cartridges are not listed on this platform — their reference single price could not be verified, and no price was invented for them.

Chip, ink and everyday use

In the set, every cartridge carries a new compatible chip. Brother's own "Cannot Detect Ink Volume" guidance for this generation states that with non-genuine ink the machine may or may not detect the cartridge — we print that warning for the J5945DW rather than promise recognition. Lifetime warranty with 1-year free returns on every cartridge.
