Choosing Between Genuine and Compatible Options
Both genuine Lexmark and compatible C540 toner cartridges are available for your office setup. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Compatible toners offer a budget-friendly solution for routine workplace documentation without compromising output sharpness. You can read more in our detailed genuine vs compatible cartridge guide.

Pro Tip
Even if you rarely print in colour, small amounts of cyan, magenta, and yellow toner are consumed during routine calibration cycles, so keeping a spare C540X75G waste toner bottle on hand prevents unexpected print halts when the current container reaches capacity.
