Toner ML-D2850B/XAA doesn't print
Problem: Samsung ML-2851 reports "Invalid toner"
XAA is, as the toner box states itself, "for sale only in Americas", it won't work on european printers.
Toners for Europe have ELS mark, written only on toner itself, not on the box. Toner's box for Europe is in green colour, and for Americas is purple one with region map and warning on it.
