Genuine OEM Lexmark X546 dtn Toners
For the X546 dtn, C540 black toner comes as individual standard- and high-yield cartridges, while C544X four-color extra-high-yield sets cover black, cyan, magenta, and yellow. Choose the individual black cartridge for one low supply, or a set when you want all four colors together.
Toner Buzz carries these genuine Lexmark toner choices along with separate C540 imaging, developer, waste, and transfer supplies. Those maintenance products serve different printer messages from toner, so choose the product type the X546 dtn identifies.
