Frequently Asked Questions

Why does this black carry the TN431 code instead of TN433?

Because the two codes are the two yield classes of one platform. TN431 is the standard-yield line: this black is rated at 3,000 pages. TN433 is the high-yield line for the very same machines, with a 4,500-page black. Neither is a newer or older version of the other — they coexist so buyers can choose between a smaller ticket now and a lower cost per page across the cartridge's life.

What does 3,000 pages work out to, page by page?

At $111.72 for the cartridge, about 3.7 cents of toner per page at rated coverage. Put it beside the high-yield black's figure of roughly 2.4 cents and you can see the trade plainly: the TN431BK keeps $100-odd less money in the printer at any moment, and charges you about a cent and a third extra for every page in exchange.

Which printers take the TN431BK?

Nine models in Brother's L8260/L8360 and L9310 colour laser lines: HL-L8260CDW, HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, HL-L9310CDWT and HL-L9310CDWTT printers, plus MFC-L8610CDW, MFC-L8900CDW and MFC-L9570CDW all-in-ones. It takes the black slot, alongside TN431 or TN433 colours in any mixture — yield classes combine freely on this platform.

TN431BK, or skip straight to the TN433BK 2 pack?

Run the honest comparison, because it is closer than you'd expect. The TN433BK twin pack sells at $212.99 — $106.50 a cartridge for 4,500 pages each. That is less per cartridge than this single TN431BK at $111.72, for half as many pages again per cartridge. If your printer earns its keep daily, the high-yield pack is the rational money. This standard cartridge is for steadier, lighter duty — or for a machine whose remaining life you wouldn't bet two cartridges on.

How many months is 3,000 pages for a small office?

At 250 pages a month, a full year. At 500 a month, half a year; at 1,000 a month, a quarter — and an office at that last pace should be reading the TN433 answer above. The TN431BK's natural home is the printer that handles the daily paperwork of a handful of people without ever becoming the office bottleneck.

What protection does a genuine cartridge come with?

It can be returned to us within 30 days of delivery whatever the circumstances, and the warranty is Brother's manufacturer warranty — full wording on our shipping and returns page. Those are the OEM terms for genuine stock; the longer cover on parts of this site applies to compatible cartridges, not to Brother's own.
