Sharp names its color toner with an MX model number, the letters NT for toner, and then a colour pair on the end. That gives sets like MX70NTCA for cyan, MX70NTMA for magenta and MX70NTYA for yellow, with MX71NTBA and MX-50NTBA covering black on their respective machines. The hyphen after MX appears on some cartridges and not others, so search on the digits.
Sharp Copier and Printer Supplies
Sharp supplies split along generational lines. The MX codes belong to the newer color range, while older Sharp copiers use ZT numbers where TD marks a toner and developer part and DR marks a drum. Fax machines use UX and FO codes instead, including thermal transfer ribbons.
