Hello Martin
Yes, 4 toners (1x black = BK, 1x cyan, 1x magenta, 1x yellow) are included when you buy the machine, see "Specifications" - "Scope of delivery".
The included toner cartridges BK: approx. 3'000 pages + CMY approx. 1'800 pages) are fully filled and correspond to the standard toner TN-421 - approx. 3'000 pages black. 1'800 pages CMY :-) :-) :-)
Optionally, even larger "Jumbo Toners" are available for "frequent printers" :-)
