Make sure Brother toner cartridge is installed in place

For Brother laser printers, Brother cartridges need to be put into corresponding Brother drum units before installing into the printers. Brother TN450 cartridge should be inserted into the slot of DR420 drum unit and the cartridge must click into place. Place the assembly into the printer and press the chip location to ensure proper contact with the printer probe.

For v4ink compatible TN450 black toner cartridge, it should be combined with v4ink DR420 or Brother DR420 drum. If it is inserted into a drum of a third-party brand, there is high chance that the cartridge will not be detected.
