The Brother TN760 is the high-yield black toner (about 3,000 pages) for the HL-L2350DW, HL-L2370DW, HL-L2390DW, MFC-L2710DW, MFC-L2750DW and related Brother lasers. The TN730 is the standard version (about 1,200 pages), and the TN770 super high-yield cartridge (about 4,500 pages) fits only four of those printers. All three work with the DR730 drum.
Below: the full printer list, the cost-per-page math, DR730 drum replacement and reset, and how to spot a genuine box.
TN730 vs TN760 vs TN770 at a glance
| Part | Type | Page yield* | Fits |
|---|---|---|---|
| Brother TN730 | Standard-yield black toner | ~1,200 pages | All 12 printers listed below |
| Brother TN760 | High-yield black toner | ~3,000 pages | All 12 printers listed below |
| Brother TN770 | Super high-yield black toner | ~4,500 pages | HL-L2370DW, HL-L2370DWXL, MFC-L2750DW, MFC-L2750DWXL only |
| Brother DR730 | Drum unit | ~12,000 pages | All 12 printers listed below |
*Toner yields per ISO/IEC 19752 at about 5% page coverage. Drum life is Brother's estimate and varies with how you print.
The TN730 and TN760 share the same housing, so they are fully interchangeable: a printer that came with a TN730 takes a TN760 (and vice versa) with no setting to change. The TN770 is the exception, and ordering it for a printer that does not accept it is the most common mistake in this family.
Which printers use the TN760 toner?
Brother lists the TN730, TN760 and DR730 for twelve monochrome laser models. The TN770 column is where they differ:
| Printer | Type | TN730 / TN760 | TN770 | DR730 drum |
|---|---|---|---|---|
| HL-L2350DW | Printer | Yes | No | Yes |
| HL-L2370DW | Printer | Yes | Yes | Yes |
| HL-L2370DWXL | Printer | Yes | Yes | Yes |
| HL-L2390DW | Printer with copy/scan | Yes | No | Yes |
| HL-L2395DW | Printer with copy/scan | Yes | No | Yes |
| MFC-L2690DW | All-in-one | Yes | No | Yes |
| MFC-L2710DW | All-in-one | Yes | No | Yes |
| MFC-L2717DW | All-in-one | Yes | No | Yes |
| MFC-L2730DW | All-in-one | Yes | No | Yes |
| MFC-L2750DW | All-in-one | Yes | Yes | Yes |
| MFC-L2750DWXL | All-in-one | Yes | Yes | Yes |
| DCP-L2550DW | All-in-one (no fax) | Yes | No | Yes |
The XL models are bundle editions of the HL-L2370DW and MFC-L2750DW and take exactly the same supplies. Brother ships the HL-L2370DWXL with one TN760 and one TN770 in the box, while a standard HL-L2350DW or HL-L2370DW comes with a starter cartridge rated for only about 700 pages. That is why the first "Toner Low" message on a new printer often arrives sooner than expected.
Not in the table? The previous generation (HL-L2340DW, MFC-L2740DW and similar) uses the TN630/TN660 cartridges covered in our TN630 vs TN660 guide, and the newer HL-L2400-series printers use the TN830 family explained in the TN830 vs TN830XL guide. Cartridges do not cross over between generations.
TN760 vs TN730 vs TN770: which costs less per page?
At current GS TONER prices the TN760 costs roughly 1.7× as much as the TN730 but prints 2.5× the pages, so each page costs about 32% less. The TN770 costs about 1.5× the TN760 and prints 1.5× the pages, so its cost per page is almost identical to the TN760 (about 2% lower).
| Cartridge | Relative toner cost per page (TN730 = 100) | Cartridges per 12,000 pages (one drum life) |
|---|---|---|
| TN730 | 100 | 10 |
| TN760 | about 68 | 4 |
| TN770 | about 67 | 2 to 3 |
In practice the TN770's advantage is convenience, not savings: on an HL-L2370DW printing 1,000 pages a month it lasts about four and a half months instead of three.
The drum is a separate cost. Spread over its 12,000 pages, a DR730 adds roughly one-third on top of the TN760's toner cost per page, so budget for one drum for about every four TN760 cartridges.
The DR730 drum: what it does and when to replace it
In these printers the toner cartridge clicks into the DR730 drum unit and the two slide into the printer as one assembly. The toner cartridge only holds powder; the drum is the light-sensitive cylinder that picks up the toner image and transfers it to the paper.
Brother rates the DR730 at about 12,000 single-sided letter pages printed one page per job. Drum life is counted in drum rotations, so actual life varies with job pattern, paper, temperature and humidity. Replace the drum when:
- the display shows Drum End Soon (order a spare now) or Replace Drum (replace it);
- prints show marks or spots that repeat at the same interval down the page, or a gray background that a new toner cartridge did not fix.
When you replace the drum, move your current toner cartridge into the new drum; there is no need to discard toner that still has pages left.
How to reset the drum counter after installing a new DR730
The printer recognizes a new toner cartridge on its own, but the drum counter must be reset by hand. Brother warns not to reset it unless you are actually installing a new drum. The key sequence depends on the control panel:
HL-L2350DW, HL-L2370DW and HL-L2370DWXL:
- Turn the printer on and make sure the front cover is closed.
- Press OK and the Up arrow at the same time.
- Press OK to select Drum.
- Press the Down arrow to reset the drum counter.
HL-L2390DW, DCP-L2550DW, MFC-L2690DW, MFC-L2710DW and MFC-L2717DW (two-line display):
- Turn the machine on and close the front cover.
- Hold down OK and press the Up arrow.
- Press OK to select Drum.
- Press the Up arrow to reset the counter.
HL-L2395DW, MFC-L2730DW, MFC-L2750DW and MFC-L2750DWXL (touchscreen): clear the error message, press and hold the icon Brother specifies for about five seconds, tap Drum Unit, then Yes. The icon is easiest to identify on Brother's reset page for these models. Our step-by-step Brother drum reset guide covers other models and what to do if the message will not clear.
How to replace the TN760 toner cartridge
- With the printer on, open the front cover.
- Pull out the toner cartridge and drum unit assembly.
- Push down the green lock lever on the drum and lift the empty toner cartridge out.
- Unpack the new cartridge and remove the protective cover.
- Push the new cartridge firmly into the drum until it locks into place.
- Clean the corona wire: slide the green tab on the drum gently left and right several times, then return it to its home position with its arrow lined up with the arrow on the drum. A tab left out of position can cause a vertical stripe on prints.
- Slide the assembly back into the printer and close the front cover.
Set the empty cartridge aside for recycling. Brother runs a free return program for its genuine cartridges, with details on Brother's TN760 page.
Genuine vs compatible TN760 cartridges
Compatible and remanufactured TN760-type cartridges are widely sold for less, and some advertise yields well above the 3,000 pages Brother rates for the genuine cartridge. Not every listing measures yield to ISO/IEC 19752, so compare like with like. Brother's user guide for these printers notes that non-Brother drum units may reduce print quality and machine life and that warranty coverage does not apply to problems they cause. Our article on how to tell if Brother toner is genuine goes deeper; the quick checks are:
- The Brother name and the part number (TN760, also printed as TN-760) appear on the box and on the cartridge label.
- The UPC on the box matches the part: TN730 012502649267, TN760 012502649274, TN770 012502649281, DR730 012502649250.
- The retail box is factory sealed and the cartridge inside is sealed with its protective cover in place.
GS TONER sells only genuine Brother cartridges, brand new and factory sealed, with free US shipping and same-day dispatch on orders placed before 2 PM ET.
Which one should you buy?
- Default choice: the TN760 for any of the twelve printers above. It costs about a third less per page than the TN730.
- HL-L2370DW or MFC-L2750DW and heavy printing: the TN770, for fewer swaps at essentially the same cost per page.
- Very light use or a printer near retirement: the TN730, for the lowest upfront cost.
- Drum: order a DR730 when Drum End Soon appears, and reset the counter only after the new drum is in.
Frequently asked questions
What is the difference between TN730 and TN760?
Only the amount of toner. Both are genuine Brother black cartridges in the same housing for the same twelve printers. The TN730 is rated at about 1,200 pages and the TN760 at about 3,000 pages (ISO/IEC 19752), so the TN760 costs less per page.
Will the TN770 work in my HL-L2350DW or MFC-L2710DW?
No. Brother lists the TN770 super high-yield cartridge only for the HL-L2370DW, HL-L2370DWXL, MFC-L2750DW and MFC-L2750DWXL. The other printers in this family take the TN730 or TN760.
How many pages does a Brother TN760 print?
About 3,000 letter pages at roughly 5% coverage, per ISO/IEC 19752. Heavy graphics, bold fonts or photos use more toner and lower the real-world yield.
Do I need a new DR730 drum every time I change the toner?
No. The toner and drum are separate parts. The DR730 is rated for about 12,000 pages, so one drum typically lasts through about four TN760 cartridges. Replace it when the printer shows Replace Drum or prints show repeating marks.
How do I reset the drum on a Brother HL-L2350DW?
After installing a new DR730, turn the printer on, close the front cover, press OK and the Up arrow together, press OK to select Drum, then press the Down arrow to reset. Reset the counter only when you actually install a new drum.
Why does my printer still say Replace Drum after I changed the toner?
The drum message tracks the drum, not the toner. Either the DR730 has reached its rated life and needs replacing, or a new drum was installed without resetting the drum counter.
