Replacing The Ink Cartridges - Brother MFC-3420C User Manual

Replacing the ink cartridges

Your MFC is equipped with an ink dot counter that automatically
monitors the ink level in each color cartridge. When the counter
detects an ink cartridge is running out of ink, the MFC will notify you
with a message on the LCD.
The LCD shows you which color cartridges are low or empty. Be sure
to follow the LCD prompts so you replace the color cartridges in the
appropriate order.
