Genuine OEM Lexmark W850 n Toners
W850H21G is the high-yield black toner for the W850 n, while W850H22G is a photoconductor. The similar numbers can be easy to mix up, but toner and the photoconductor handle different printer needs.
Toner Buzz carries both genuine Lexmark supplies, plus the 40X0956 maintenance kit. Choose W850H21G for a low-toner message and the photoconductor or maintenance kit only when the printer names that part.
