MFC-J430W

The MFC-J430W's own pairing is LC71 below and LC75 above: same slots, double the pages (300 against 600 per cartridge, ISO/IEC 24711). The LC75 cartridges on this page are the official high-yield counterpart to the standard LC71 — which is why this store sells the LC75 as the step-up for this printer rather than opening a separate LC71 range. The third tier in the family, LC79, is not an option here at all: the MFC-J430W physically cannot accept an LC79 cartridge, and sellers who list it as fitting are wrong.

Judge the MFC-J430W's two tiers on Brother's own measure: both are rated to ISO/IEC 24711, so 300 pages for the standard LC71 against 600 for the LC75 is a like-for-like comparison — the same slots, at double the fill. Priced at $8.24 for up to 600 pages, an LC75 runs about 1.4 cents a page and halves how often a position needs changing. The LC79 super-high tier does not fit this printer at all, and no bigger cartridge is waiting later: LC75 is the ceiling. It is stocked as singles and in two sets, so black-heavy printing never forces a color purchase, and as the only tier covering all 11 family printers it is the safest code to keep on the shelf.

Which LC75 should you buy?

One color at a time: black, cyan, magenta and yellow — $8.24 each.
Full refresh: the Set of 4 ($29.94) puts one of each color in one box.
Print every week: the Set of 10 ($67.35) puts four blacks and two of each color in one box.

Chip, ink and everyday use

The risk cover on an MFC-J430W cartridge is plain: every Clever Supplies LC75 carries a lifetime warranty with 1-year free returns. The system behind it is fully individual — four slots, four separate chipped cartridges, each swapped on its own — and a new cartridge should be handled by the housing, with fingers kept off the chip contact.
