Toner, drum unit and waste toner tank – what your Lexmark C543DN needs When you search for toner for Lexmark C543DN (also known as C543DN, C543 dn, C543 DN or C543dn), you’re usually looking for one of three key supplies: - Toner cartridges (black, cyan, magenta, yellow) – responsible for the colour and text on the page.
