tn760 vs tn770 — both Brother black toners, but they are not a simple yield swap for every printer. Check the label (and the printer model) before you buy.
TN760 is about 3,000 pages. It covers a wide HL-L / MFC-L / DCP-L set in this family.
TN770 is about 4,500 pages. Same fit on the overlap printers only: HL-L2370DW and MFC-L2750DW (and XL). It does not fit the broader TN760 list (HL-L2350DW / L2390DW / L2395DW · MFC-L2690DW / L2710DW / L2717DW / L2730DW · DCP-L2550DW).
| Feature | TN760 | TN770 |
|---|---|---|
| Black yield | ~3,000 | ~4,500 |
| Best for | Regular use on supported printers | Higher volume on overlap printers only |
| Overlap printers | HL-L2370DW; MFC-L2750DW / L2750DW XL | |
| TN760-only (examples) | HL-L2350DW / L2390DW / L2395DW · MFC-L2690DW / L2710DW / L2717DW / L2730DW · DCP-L2550DW — use TN760, not TN770 | |
Mono black only. Not TN730 / TN660 / TN830 as a required buy. Read the label on the cartridge already in the printer.
We sell a compatible TN760 black and a compatible TN770 black, chips installed.
When to buy which: first confirm the printer is on the overlap list. If it is, and you replace toner often → TN770 (about 1.5× the pages). If the printer is on the broader TN760-only list, or the label already says TN760 and the machine is not HL-L2370DW / MFC-L2750DW → stay on TN760. Never pick TN770 for yield alone when the printer is outside the overlap.
FAQ
What is tn760 vs tn770 in one sentence?
Both are Brother blacks; TN770 is higher yield (~4,500 vs ~3,000) but only fits HL-L2370DW / MFC-L2750DW — not every TN760 printer.
Can I put TN770 in a printer that came with TN760?
Only if that printer is HL-L2370DW or MFC-L2750DW (or XL). Broader TN760 machines need TN760, not TN770.
Is there a TN760 / TN770 4-pack?
No. These are single black cartridges only.
Does compatible toner void the printer warranty?
Using a third-party cartridge does not by itself void Brother’s limited printer warranty. Damage Brother attributes to a non-Brother cartridge is a different question.
