Setup, Compatibility & Care
To install the TN423C, open your Brother printer's front cover and remove the existing drum unit and toner cartridge assembly. Press the green lock lever to release the old toner, insert the Alpa-Cartridge, and lock it into place. Ensure the corona wire inside the drum unit is clean before sliding the assembly back into the printer. This cartridge is explicitly compatible with the following models: DCP-L8410CDW, HL-L8260CDW, HL-L8360CDW, MFC-L8690CDW, and MFC-L8900CDW. Store unused cartridges in a cool, dark, and dry environment to prevent premature toner settling.
