Brother TN-627BK — Black Ultra High Yield Toner Cartridge
Approx. 10,000 pagesTop of the TN-625 ladderISO/IEC 19798Three machines only
The Brother TN-627BK is the largest black cartridge in Brother’s TN-625 colour laser family, rated at approximately 10,000 pages measured to ISO/IEC 19798. It sits above the standard TN-625BK at 3,000 pages, the TN-625XL at 5,500 and the TN-625XXL at 7,500 — and unlike those three, Brother restricts it to the top machines in the range. That restriction is the single most important thing to check before ordering, because the TN-625 cartridges fit six printers and the TN-627 fits only three of them. It is a toner cartridge only; the drum DR-625CL is a separate part rated at around 30,000 pages.
Compatibility — check before buying:
This cartridge fits the HL-L8570CDW, the MFC-L8970CDW and the MFC-EX570. It will NOT fit the HL-L8430CDW, the DCP-L8630CDW or the MFC-L8730CDW, even though those three machines take the TN-625, TN-625XL and TN-625XXL cartridges from the same family. Brother reserves the ultra-high-yield tier for the larger models. If your machine is one of the smaller three, the TN-625XXL at 7,500 pages is the highest black cartridge available to you. One more thing worth stating plainly: Brother publishes no TN-623 and no TN-626 for this series — the ladder is TN-625, TN-625XL, TN-625XXL and TN-627, and those three-number codes belong to the older HL-L8260 and HL-L8360 generation.
Best For
✓ High-volume mono and colour printing on an HL-L8570CDW
✓ MFC-L8970CDW and MFC-EX570 workgroups
✓ Sites wanting the fewest black cartridge changes
✓ Lowering cost per page on a busy colour laser
✓ Departments where black outruns the colours
✓ Keeping a spare black for a machine that cannot stop
Key Features
Ten thousand pages, the top of the ladder
Brother publishes four black capacities for this family: 3,000, 5,500, 7,500 and 10,000 pages. This is the largest, and per page it is normally the cheapest — on machines that accept it.
Measured to ISO/IEC 19798
The yield is declared in accordance with the international standard, on A4 or Letter single-sided pages, which makes it directly comparable with cartridges from other manufacturers measured the same way.
Black outlasts the colours by design
On this family the colour cartridges run 1,800 to 6,500 pages depending on tier, while this black runs 10,000. For the typical office mix of mostly black text with occasional colour, that keeps the replacement cycle sensible.
Toner only — the drum lasts far longer
The DR-625CL drum is rated at approximately 30,000 pages and serves all four colours from one unit. The belt BU635CL and waste toner box WT229CL are rated around 50,000 pages each. Buying toner alone leaves those in place.

Frequently Asked Questions
Will it fit my printer?
Only three machines: HL-L8570CDW, MFC-L8970CDW and MFC-EX570. If you have an HL-L8430CDW, a DCP-L8630CDW or an MFC-L8730CDW, this cartridge will not work in it even though those printers use the same TN-625 family for their other tiers. The highest black available to those three is the TN-625XXL at 7,500 pages. Send us the model badge if you are unsure.
Why is the black yield higher than the colours?
On the standard, XL and XXL tiers Brother rates black higher than the colours, which reflects the way most offices print. On the TN-627 tier all four colours are rated at 10,000 pages. If you print mostly black text with occasional colour, black is the cartridge you will replace most often, and this is the one that stretches that interval furthest.
Do I need a new drum too?
Not usually. The DR-625CL is rated at approximately 30,000 pages and serves all four colours from a single unit, so it spans about three of these black cartridges. The belt unit and waste toner box run to around 50,000 pages each. The printer reports each part separately and tells you when it is genuinely due.
I have seen TN-623 and TN-626 mentioned. Are those the same?
No, and Brother does not publish either for this series. The ladder here is TN-625, TN-625XL, TN-625XXL and TN-627. The three-number pattern comes from the previous colour generation, the HL-L8260 and HL-L8360 machines, which used TN-421, TN-423 and TN-426. If a listing offers you a TN-626 for an HL-L8570CDW, something is wrong with it.
Singular Expert Insight
Two things decide whether this is the right cartridge. The first is fitment, and it is unusually restrictive: Brother sells six machines that take the TN-625 family but only three that take this ultra-high-yield tier. The HL-L8430CDW, DCP-L8630CDW and MFC-L8730CDW are excluded, and it is an easy mistake because the cartridges look like siblings on a shelf. The second is volume. At 10,000 pages this is the cheapest black per page in the range, but on a machine printing a few hundred pages a month a cartridge that size may sit in the printer for years, and the XXL at 7,500 or even the standard at 3,000 may suit better. Also worth knowing: on this tier Brother rates all four colours at 10,000 pages, so a full set depletes evenly rather than the colours running out first. Send us your model number and your monthly page count and we will tell you which rung is genuinely cheapest. The rest of the range is in our
original toner section, and the machines in
colour laser printers.
