Setup, Compatibility & Care
To install, open the front cover of your compatible Brother printer and pull out the toner cartridge and drum unit assembly. Remove the used cartridge by pushing down the green lock lever and pulling it out of the drum. Slide the new TN-423Y into the drum until you hear a click. Ensure the corona wire inside the drum unit is cleaned by sliding the green tab back and forth several times.

Store unused cartridges in a cool, dark place and keep the sealed packaging intact until the moment of installation to prevent moisture buildup or toner degradation.
