One Brother workgroup platform takes four black toner cartridges — TN820, TN850, TN880 and TN890 — rated from about 3,000 pages up to about 20,000, all of them sliding into the same toner bay and all of them paired with a separate drum. Because the two smaller cartridges sit at identical prices on our shelf while one is rated for well over twice the pages of the other, the yield ladder matters more here than the sticker. This guide climbs that ladder rung by rung, then deals with the drum split at the top of the range, where five of the biggest machines quietly take a different drum than the rest.
The short answer: buy the highest-yield cartridge your model accepts. For most machines on this platform that is the TN850, and the 2-pack at $42.07 is the box to start with — about 16,000 pages at roughly 0.26¢ a page, with a sealed spare in the drawer.
The TN850 2-pack at $42.07 is the default buy for this platform: two cartridges rated at about 8,000 pages each, $16.07 below the price of two singles. Owners of the ten largest models can step up to the TN880 (about 12,000 pages, same $42.07 2-pack), and the three flagship machines take the TN890 (about 20,000 pages). The standard TN820 costs exactly what the TN850 costs at every pack size and is rated for 5,000 fewer pages, so at today's prices it is the like-for-like replacement, not the value pick. The DR820 drum is a separate purchase on its own long cycle — and five models at the top of the range need the DR890 drum instead.
One platform, four yield steps
Brother built this generation of monochrome workgroup machines around a single toner bay, then sold four fill levels for it. The TN820 is the standard cartridge at about 3,000 pages. The TN850 raises that to about 8,000, the TN880 to about 12,000 and the TN890 to about 20,000 — Brother's own ISO/IEC 19752 ratings, and the figures printed on the cartridges themselves. The cartridges are the same shape and the same black; what changes is how much toner is inside and, crucially, which machines are allowed to use each step.
The two lower steps fit every machine on the platform. The twenty-two models are the DCP-L5500DN, DCP-L5600DN, DCP-L5650DN, HL-L5000D, HL-L5100DN, HL-L5200DW, HL-L5200DWT, HL-L6200DW, HL-L6200DWT, HL-L6250DW, HL-L6300DW, HL-L6400DW, HL-L6400DWT, MFC-L5700DW, MFC-L5800DW,MFC-L5850DW, MFC-L5900DW, MFC-L6700DW, MFC-L6750DW, MFC-L6800DW, MFC-L6900DW, plus the MFC-L5705DW, which Brother lists for this family but which has no model page in our store. Any of those machines accepts either a TN820 or a TN850, so for most owners the standard cartridge is simply an option to skip past.
The ladder narrows as it climbs. The TN880 fits only ten of the models — the HL-L6200DW, HL-L6200DWT, HL-L6250DW, HL-L6300DW, HL-L6400DW, HL-L6400DWT, MFC-L6700DW, MFC-L6750DW, MFC-L6800DW, MFC-L6900DW. The TN890 narrows the field to three flagships: the HL-L6400DW, HL-L6400DWT and MFC-L6900DW. A smaller machine cannot use the bigger cartridges, so the first step in this guide is always the same: find your model, then take the highest rung it offers.
If your Brother is an older or smaller machine that takes none of these numbers, it belongs to a different family — the TN760 generation is covered in our Best Brother TN760 Toner Cartridges guide.
The family side by side
Every price below was read from the product pages linked in this guide. Yields are Brother's ratings. The genuine Brother column is the price of the same cartridge in a Brother box on our own OEM shelf, shown so the compatible figures have something honest to stand against.
| Cartridge | Compatible single | Compatible 2-pack | Brother-rated yield | Cost per page, single | Genuine Brother single |
|---|---|---|---|---|---|
| TN820 | $29.07 | $42.07 | About 3,000 pages | About 0.97¢ | $98.69 (about 3.29¢/page) |
| TN850 SWEET SPOT | $29.07 | $42.07 | About 8,000 pages | About 0.36¢ | $140.79 (about 1.76¢/page) |
| TN880 | $29.07 | $42.07 | About 12,000 pages | About 0.24¢ | $161.29 (about 1.34¢/page) |
| TN890 | $36.94 | $57.80 | About 20,000 pages | About 0.18¢ | $199.99 (about 1.00¢/page) |
| DR820 drum | $30.04 | $44.00 | About 30,000 pages | About 0.10¢ | $159.29 (about 0.53¢/page) |
The drum's 30,000-page rating assumes an average of one page per print job; Brother rates the same drum at about 50,000 pages when jobs average three pages. Real toner yields vary with page coverage, printer settings and paper — the ratings are the comparison standard, not a promise for any single office.
The 5-second decision
This is the box most owners of these machines should buy. It prices the platform's workhorse cartridge at roughly 0.26¢ a page, and the second cartridge means the low-toner warning becomes a short swap instead of a stalled afternoon. A genuine Brother TN850 single, rated for the same 8,000 pages, is $140.79 on our OEM shelf — more than three of these 2-packs.

If your model is one of the ten that accepts it, the TN880 is the arithmetic winner on the toner side: the 2-pack costs no more than the TN850's and carries about 8,000 extra pages. Buy the listings carded in this guide — an older set of TN880 listings on our shelf is priced a little higher for the identical cartridge, which we flag in the TN880 section below.
View the TN880 2-Pack →TN850: the workhorse step
The TN850 is the cartridge this platform was really built around: about 8,000 pages, a $29.07 single, and a place in every one of the twenty-two machines. At about 0.36¢ a page for the single and 0.26¢ in the 2-pack, it undercuts the standard cartridge it shares a shelf with by nearly two-thirds per page, and it stays the right answer for every model that cannot climb to the TN880. The bigger boxes stretch the same cartridge further — about 0.23¢ a page in the 3-pack, 0.20¢ in the 5-pack and 0.18¢ in the 10-pack.
Two duplicate listings are worth knowing about so you can recognize them rather than wonder about them: a second TN850 2-pack listing exists at the identical $42.07, and a "Premium Quality" 5-pack listing exists at the identical $81.05 to the 5-pack carded below. Same cartridge, same price — the cards here are simply the listings we verified for this guide, and either route costs the same.
TN820: the standard cartridge, honestly priced
Here is the unusual thing about this family's shelf, and this guide will not dress it up: the TN820 and the TN850 are priced identically at every pack size — $29.07 for a single, $42.07 for two, $55.06 for three, $81.05 for five, $146.01 for ten — while Brother rates the TN820 at about 3,000 pages and the TN850 at about 8,000. Per page that is roughly 0.97¢ against 0.36¢ for the identical outlay. Since every printer that takes a TN820 also takes a TN850, the higher-yield cartridge is the better buy at these prices, full stop.
So why does the TN820 stay in this guide at all? Because some buyers replace like for like — an office standardizing on the cartridge named in its printer's manual, or a first compatible purchase kept deliberately identical to the genuine cartridge it replaces (a genuine Brother TN820 is $98.69). If that is you, the packs below are the same ladder as the TN850's, rung for rung; just know the ladder you actually want is one section up.
TN880: more pages, fewer printers
The TN880 pushes the rating to about 12,000 pages, and our shelf prices its current listings on the same template as the TN850 — a $29.07 single and a $42.07 2-pack — which makes it about 0.24¢ a page singly and 0.18¢ in the 2-pack. The catch is fit: only the ten larger models listed in the platform section can use it. If yours is a 5000-series machine, this section is not yours no matter how good the arithmetic looks; the TN850 is your top rung.
One shelf warning, because it is exactly the kind of thing that confuses a careful buyer: TN880 cartridges appear in our store under two generations of listings. The older generation prices the single at $29.85 and the 2-pack at $43.61; the current listings carded here price the identical cartridge at $29.07 and $42.07. A fourth listing sells the 4-pack under a title that never says "Pack" — it is the same $68.05 as the 4-pack carded below. Buy the carded listings and you pay the lower figure at every size; the savings figures on this page are all computed from those carded prices.
TN890: the flagship-only cartridge
The TN890 is the top of the ladder: about 20,000 pages per cartridge, the longest toner interval Brother offers on this platform, and at $36.94 for a single it works out to about 0.18¢ a page before any pack discount — the 4-pack takes it to roughly 0.12¢, the lowest figure in the family. Against a genuine Brother TN890 at $199.99, the compatible single is less than a fifth of the price for the same rated yield.
It serves exactly three machines — the HL-L6400DW, HL-L6400DWT and MFC-L6900DW — and owners of those machines should read the drum section next with care, because all three pair this toner with the DR890 drum rather than the DR820 the rest of the platform uses.
The DR820 drum — and the five machines that take a different one
These printers split toner and imaging into two parts. The cartridge holds the powder; the drum unit is the cylinder it sits in, and it is replaced separately, far less often. Brother rates the DR820 at about 30,000 pages when jobs average one page each, and about 50,000 pages when jobs average three pages — drum wear is counted per job as well as per page, so long print runs are gentler on it than the same pages sent one at a time. At $30.04, the compatible drum adds roughly 0.10¢ to the cost of a page on the one-page basis; a genuine Brother DR820 is $159.29, which is also Brother's own list price for the part.
Brother's own DR820 page lists seventeen models it works with: the three DCP machines, the HL-L5000D, HL-L5100DN, HL-L5200DW, HL-L5200DWT, HL-L6200DW, HL-L6200DWT and HL-L6300DW, and the MFC-L5700DW, MFC-L5705DW, MFC-L5800DW, MFC-L5850DW, MFC-L5900DW, MFC-L6700DW and MFC-L6800DW. Five machines in this printer range are not on that list — the HL-L6250DW, HL-L6400DW, HL-L6400DWT, MFC-L6750DW and MFC-L6900DW take the DR890 drum instead. That includes every TN890 machine. We stock the DR890 only as a genuine Brother unit, and no compatible version of it is sold here; if your machine is one of the five, shop by the drum code, not by the toner family, and do not let a model-page listing talk you into a DR820.
A naming warning while we are here: a few of our drum listings wear "Toner Cartridge" titles even though the product is a drum unit — read the DR820 code and the drum description, not the headline. And if you came here searching for a "DR850", there is no such Brother part; the drum for this platform is the DR820 (or the DR890 on the five machines above), which is almost certainly what the search meant.
Toner and drum together: the TN880 sets
Every combination set on our shelf for this family pairs the DR820 drum with TN880 toner, which makes the sets a ten-model story: they suit the machines that take both parts — the 6200, 6300 and 6400-series printers and the 6700 and 6800 all-in-ones from the TN880 list, minus the three DR890 machines named above. When a printer asks for a drum while a toner change is also on the horizon, a set prices the pair below the separate parts: $16.08 below on the one-and-one set, rising to $48.23 below on the three-toner and two-drum sets.
Each set also exists under a second, duplicate listing at the identical price — and one further two-drum, two-toner listing costs $1.55 more than the set carded here. The cards below are the verified, better-priced route to each combination.
Toner and drum run on different clocks
Because the two parts wear separately, they also complain separately. A "Replace Toner" message is about the cartridge; a "Replace Drum" message is about the DR820's own counter, and no fresh toner cartridge will clear it. On the one-page-per-job rating, one drum outlasts about ten TN820 cartridges, roughly four TN850s, or about two and a half TN880s — which is why the drum belongs in a buying guide but not in every order. Pages that stay faint or streaked after a new cartridge goes in are the drum's other way of asking.
Chip and reset questions deserve a straight answer about this family in particular: none of the listings in it claims a newly fitted chip, and the few that mention a chip at all repeat a standard parts-list sentence — the same sentence even appears on drum units, which carry no toner chip to speak of. Brother's published position on firmware and third-party cartridges, the exact drum-reset steps for these machines, and the "Cannot Detect" and "No Toner" messages are collected in one place: our Brother Monochrome Toner & Drum Compatibility page.
Before you order: the TN850 family checklist
Frequently asked questions
The TN850, in almost every case. Both cartridges fit all twenty-two printers on this platform, and at the identical $29.07 single price the TN850 is rated for about 8,000 pages against the TN820's 3,000 — roughly 0.36¢ a page against 0.97¢. The TN820 remains the like-for-like choice for buyers who deliberately replace the exact cartridge named in their manual.
No. The TN880 fits only the ten larger models — the HL-L6200DW, HL-L6200DWT, HL-L6250DW, HL-L6300DW, HL-L6400DW and HL-L6400DWT printers and the MFC-L6700DW, MFC-L6750DW, MFC-L6800DW and MFC-L6900DW all-in-ones. The 5000-series machines top out at the TN850, which is still an 8,000-page cartridge.
The DR890. Brother's own DR820 page omits the HL-L6400DW, HL-L6400DWT, HL-L6250DW, MFC-L6750DW and MFC-L6900DW from its list of seventeen models, and those five machines use the DR890 drum. We sell the DR890 only as a genuine Brother unit; there is no compatible version of it on our shelf.
No — Brother makes no cartridge or drum called DR850. The drum unit for this platform is the DR820, with the DR890 serving the five top models named above. Searches for “dr850” almost always mean one of those two parts.
Brother rates it at about 30,000 pages when print jobs average one page, and about 50,000 pages when jobs average three pages, because the drum cycles once per job as well as turning per page. The printer counts drum life separately and shows a “Replace Drum” message when the rating is reached; streaking or fading that survives a fresh toner cartridge is the earlier, visible sign.
Straight answer: no listing in this family claims a newly fitted chip, and most say nothing about chips at all — the handful that mention one repeat a standard parts-list sentence. Brother's published position is that its firmware updates do not block third-party toner cartridges, and the full wording, plus the drum-reset steps and the “Cannot Detect” and “No Toner” messages, are set out on our Brother Monochrome Toner & Drum Compatibility page.
Because the cartridge is listed twice, from two generations of listings. The older listing prices the single at $29.85 and the 2-pack at $43.61; the current listings carded in this guide price the identical cartridge at $29.07 and $42.07. The pack savings quoted on this page are computed from the carded listings.
Every compatible toner cartridge and drum unit in this family is covered by our 1-year warranty, with a full year to return a cartridge that is not right. Orders ship from our warehouses in Illinois, Pennsylvania, Georgia and California, and support runs Monday through Friday, 9 AM to 5 PM Central.
