Frequently Asked Questions

The TN433BK costs barely a dollar more than the standard black — where is the catch?

There isn't one, and the comparison is worth doing slowly. The standard TN431BK is $111.72 on this site; this TN433BK is $113.16 — a difference of $1.44. For that dollar and change, the rated fill rises from 3,000 pages to 4,500. Brother prices the two blacks close together because they share a shell and a production line; the extra money is essentially paying for toner powder, and toner powder is the cheapest part of any cartridge. As value gaps go, it is the widest one on this platform.

What does a black page actually cost with this cartridge?

About 2.5 cents. Divide $113.16 by the 4,500-page rating and you get 2.51 cents a page, against 3.72 cents a page for the standard TN431BK and $158.42 list price on this very cartridge, which would put it near 3.5 cents. Ratings assume the standard 5% coverage test page, so dense documents will land higher — but the ranking never changes: page for page, this is the cheapest genuine black the platform takes, short of the two-cartridge pack.

Should I be looking at the 2 pack of this cartridge instead?

If your printer earns its keep daily, honestly, yes. The TN433BK 2 pack is $212.99 — $106.50 a cartridge, which undercuts this single's $113.16 while doubling the stock on your shelf to 9,000 rated pages. The single makes sense when the machine is new to you, when volume is unproven, or when one cartridge genuinely covers a quarter's printing. Nothing about the single is poor value; the pack is simply better arithmetic for established workloads.

Which printers does the TN433BK fit?

Ten models run this black: the HL-L8260CDW, HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, HL-L9310CDWT and HL-L9310CDWTT printers, and the MFC-L8610CDW, MFC-L8900CDW, MFC-L9570CDW and MFC-L9570CDWT all-in-ones. Check the code on the cartridge you are replacing — if it reads TN431BK, this cartridge still drops into the same slot as the higher-capacity option; if it reads TN433BK, you are looking at the exact refill.

How long will 4,500 pages last in a real office?

At a modest 300 black pages a month, well over a year. At 750 a month — a small team sharing one machine for correspondence and filing — around six months. Heavy monochrome runs, statements or case bundles at 1,500 pages a month, turn it over in a quarter. The point of the high-yield fill is not just the lower cost per page; it is halving the number of times a busy printer stops mid-job waiting for someone to find the spare.

What are the return terms on this cartridge?

Straightforward OEM terms: you have 30 days from delivery to return it, in all cases, and the cartridge carries Brother's manufacturer warranty behind that — the full text is on our shipping and returns page. Orders ship from the nearest of our Illinois, Pennsylvania, Georgia and California warehouses, and the support team keeps Monday to Friday hours, 9 AM to 5 PM CST.
