Brother TN-3520 — Black Ultra High Yield Toner Cartridge
Approx. 20,000 pagesISO/IEC 19752Genuine BrotherDrum DR-3400 sold separately
The Brother TN-3520 is a genuine black toner cartridge in the ultra high yield tier for Brother’s HL-L5000 to HL-L6400 and DCP/MFC-L5500 to L6900 mono laser platform. Brother rates it at approximately 20,000 pages, measured in accordance with ISO/IEC 19752 on A4 or Letter single-sided pages. It is the top of the four-rung ladder on this platform, above the 12,000-page TN-3512, the 8,000-page TN-3480 and the 3,000-page TN-3430. It is a toner cartridge only — the drum unit DR-3400 is a separate part that outlasts several cartridges, so replacing toner does not mean replacing the imaging drum.
Compatibility — check before buying:
Fitment is the thing to get right on this range, because Brother restricts the higher-yield cartridges to the more capable machines. This cartridge fits three machines only: the HL-L6400DW, the HL-L6400DWT and the MFC-L6900DW. It will NOT fit the HL-L6300DW, HL-L6300DWT, HL-L6250DN, DCP-L6600DW or MFC-L6800DW, nor anything in the L5000, L5100, L5200, L5500, L5700 or L5750 range — Brother restricts the Ultra High Yield rung to the top three machines, and this is the classic mis-order on this platform. There is a second and larger trap: Brother runs two mono generations that look alike. The TN-3430, TN-3480, TN-3512 and TN-3520 cartridges with the DR-3400 drum belong to the HL-L5000 to HL-L6400 platform; the newer TN-3600 family with the DR3600 drum belongs to the HL-L5210, HL-L6415, MFC-L5710 and MFC-L6915 machines. They are not interchangeable in either direction. Check the exact model badge before ordering, or send it to us and we will confirm.
Best For
✓ Mono laser printing in offices and workgroups
✓ Sites that want genuine supplies with a declared ISO yield
✓ Replacing toner without touching the drum
✓ Departments printing text documents in volume
✓ Keeping a spare cartridge for a busy machine
✓ Predictable per-page costs
Key Features
Approximately 20,000 pages, measured to standard
Brother declares the yield in accordance with ISO/IEC 19752, the international standard for monochrome page yield, on A4 or Letter single-sided pages. That makes it comparable with other manufacturers measured the same way.
Ultra High Yield in a four-step ladder
Brother publishes four capacities for this platform: TN-3430 at approximately 3,000 pages, TN-3480 at 8,000, TN-3512 at 12,000 and TN-3520 at 20,000. Higher-yield cartridges are normally cheaper per page, but not every machine accepts every rung.
Genuine Brother, matched to the engine
A genuine cartridge is matched to the printer’s fuser temperature and toner-level sensing, which is what keeps density even through a long run and keeps the remaining-life reporting accurate.
Toner only — the drum lasts far longer
The DR-3400 drum is rated at approximately 30,000 pages at one page per job, or 50,000 at three pages per job. That is several cartridges worth, so buying toner alone avoids discarding a drum with plenty of life left.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
On this platform the sensible question is not genuine versus compatible, it is which rung of the ladder your machine will take. Brother publishes four capacities from 3,000 to 20,000 pages, and per page the larger cartridges are normally cheaper — but the top two rungs are restricted to the more capable machines, so the cheapest option on paper is often not available to you. On this cartridge the restriction is the whole story: three machines take it and everything else in the range does not, which makes it the most commonly mis-ordered part on this platform. If you do have an HL-L6400DW, HL-L6400DWT or MFC-L6900DW, it is the cheapest rung per page by a clear margin and roughly halves the number of cartridge changes against the 12,000-page TN-3512. The other thing to watch is the generation split. Brother sells two mono families that look almost identical on a shelf: TN-34xx and TN-35xx with the DR-3400 drum for the HL-L5000 to L6400 machines, and the newer TN-36xx with the DR3600 drum for the HL-L5210 and L6415 machines. Ordering across them is the single most common error we see, and neither cartridge will physically go into the other printer. Send us your model number and monthly page count and we will tell you which cartridge is cheapest to run. The full range is in our original toner section, and the machines in mono laser printers.
