@uninventive @Heterokromia @yogthos I’m referring to laser toner cartridges, there’s no IR window on those that I know of. The printer just keeps track in memory of the remaining page count and you used to be able to reset the count if the cartridge still has some toner and the printer declares it empty. Brother did not try to lock out third party toner cartridges until fairly recently.
