The Brother machine has separate consumables the toner cartridge and the drum unit. Verify you replace only the drum unit and not the toner cartridge. If you want to know their difference, refer to "What is the difference between the toner cartridge and the drum unit?"
Please reset the drum counter only when you replace the drum unit. If you reset the drum counter during the life of the drum unit currently being used, the remaining drum life will not be displayed accurately.

Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability.
