Questions about this item

Which printer models will accept the two black cartridges in this pack?

The cartridges replace Brother TN660 and TN630 and work with HL-L2300D, HL-L2320D, HL-L2340DW, HL-L2360DW, HL-L2380DW, DCP-L2520DW, DCP-L2540DW, MFC-L2700DW, MFC-L2720DW and MFC-L2740DW.

Will the cartridges operate reliably in a printer that has been running for several years?

They are rated for 10 to 32.5 °C operating temperature and 20 to 80 % RH humidity, matching the environmental limits of the compatible Brother printers.

How can I confirm each cartridge is delivering the rated output after installation?

Print a test page and check the printer's page counter; each cartridge should yield about 2600 pages at 5 % coverage before the toner-low indicator appears.
