Genuine OEM Sharp MX-4141N Toners

For the MX-4141N, MX51 toner and the MX31NRSA drum belong to the same printer but serve different supply needs. The drum's MX31 name doesn't make it an MX51 toner alternative: it is a separately supplied maintenance part.

Toner Buzz carries genuine Sharp MX51 black and color cartridges individually and in a four-color toner set. The set groups black, cyan, magenta and yellow. MX51 developer for black or the three colors and the MX31NRSA drum are separate choices for maintenance.
