Can I use non-Brother or third party supplies with the Brother machine?

I just replaced the toner cartridge and the LCD continues to display the message "Toner Low" / "Replace Toner" / "Toner Ended" or the Toner LED is still on or flashing.

Check the remaining ink or toner level (Linux)

Replace Drum

Reset the Drum Counter

I still receive the error message "Replace Drum", "Drum End Soon", or "Drum Stop" after I replace the drum unit with a new one.

Check the Remaining Life of Parts

What is the difference between the toner cartridge and the drum unit?
