What is Brother TN660 Toner & Which Printers Use It?

by William Elward Last Updated:

Quick answer: Brother TN660 is a high-yield black laser toner cartridge that fits a long list of Brother HL, MFC, and DCP series printers. It yields about 2,600 pages — roughly 2x the standard TN630 — and is one of the most popular replacement toners for small-office Brother lasers.

Brother Printers That Use TN660 Toner

  • Brother HL-L2300D, HL-L2305W, HL-L2315DW, HL-L2320D, HL-L2340DW, HL-L2360DW, HL-L2380DW
  • Brother MFC-L2680W, MFC-L2685DW, MFC-L2700DW, MFC-L2705DW, MFC-L2707DW, MFC-L2720DW, MFC-L2740DW
  • Brother DCP-L2520DW, DCP-L2540DW, DCP-L2541DW, DCP-L2550DW

If your Brother printer model also accepts TN630 (the standard-yield version), it will accept the higher-yield TN660 as well. The two cartridges are physically the same shape and use the same drum unit (DR630).

TN630 vs. TN660: Which Should You Buy?

TN630 yields ~1,200 pages. TN660 yields ~2,600 pages. The TN660 typically costs only modestly more than the TN630, so the cost-per-page on TN660 is significantly better. Unless you almost never print, TN660 is the smart pick. Like a lot of laser supplies, the savings get bigger the more you print — see our Brother L2000-series toner guide for related models.

How to Replace TN660 Toner in a Brother Laser Printer

  1. Power on the printer and open the front cover.
  2. Slide out the drum unit and toner cartridge assembly together.
  3. Push down the green release lever on the drum, then lift the empty TN660 toner out of the drum unit.
  4. Unwrap the new TN660 cartridge and gently rock it side-to-side a few times to distribute the toner powder.
  5. Slide the new toner into the drum unit until it clicks into place. The green lever should reset automatically.
  6. Reinstall the drum-and-toner assembly in the printer and close the front cover.

Troubleshooting Tips

  • "Replace toner" message after installing a new cartridge: Brother printers track toner usage through a sensor and software counter. Reset the toner counter from the printer's panel by following the brand's official Brother HL-L2340DW support page instructions, which apply to most TN660-compatible models.
  • Faded prints: Remove the drum-and-toner unit and rock it gently to redistribute toner. If fading continues, the cartridge is genuinely empty.
  • Streaks or vertical lines: Usually indicates a dirty corona wire on the drum unit — slide the green tab back and forth a few times to clean it.

Bottom Line

Brother TN660 is a high-yield (~2,600 pages) black laser toner used by dozens of HL, MFC, and DCP series Brother printers. It's nearly always cheaper per page than the standard TN630, and Castle Ink's compatible version delivers OEM-equivalent quality at less than half the OEM price.
