Replacement for Brother TN660 TN630

This eSquareOne compatible cartridge replaces Brother TN660 and TN630 black toner supplies. It fits Brother HL-L2300D, HL-L2320D, HL-L2340DW, HL-L2360DW, HL-L2380DW, DCP-L2520DW, DCP-L2540DW, MFC-L2700DW, MFC-L2720DW and MFC-L2740DW printers. The single black unit is new and ready to install.

Yield measured at five percent coverage

The approximate page yield is 2600 pages when printed at five percent coverage. Actual output varies with document density, print settings and environmental conditions. Operating temperature range is 10 to 32.5 degrees Celsius with humidity between 20 and 80 percent RH. Storage limits extend from minus 20 to 40 degrees Celsius at the same humidity band.

Upgrade from standard yield cartridges

This high-yield unit suits offices that print enough to benefit from fewer cartridge changes. It is not for users who need colour output or who operate printers outside the listed Brother series. The jump is worth it when monochrome volume justifies the larger toner capacity over the standard TN630 alternative.

Questions about this item

Should I pick the TN660 or TN630 replacement option for my Brother printer?

The cartridge replaces both Brother TN660 and TN630 black toners, so either option fits the same compatible printers listed.

How many pages will the 2600-page yield actually deliver in daily office use?

The 2600-page estimate is based on 5% coverage; heavier text or graphics will reduce the count, while lighter printing can extend it.

Does the cartridge use a proprietary chip or standard interface that could limit printer recognition?

It is engineered as a direct replacement for Brother TN660/TN630 cartridges and works with the listed HL-L2300D, HL-L2320D, HL-L2340DW, HL-L2360DW, HL-L2380DW, DCP-L2520DW, DCP-L2540DW, MFC-L2700DW, MFC-L2740DW and MFC-L2720DW models.
