Genuine OEM Lexmark X215 Toners
The Lexmark X215 uses 18S0090 black toner for its single toner position. There is no color set or alternate toner capacity to choose, so the 18S0090 part number is the important detail to match.
Toner Buzz carries genuine Lexmark 18S0090 toner for this machine. Compare that code with the toner notice or current cartridge before ordering, especially when other Lexmark black cartridges have similar names.
