Evil is not : Have nacheinender posted 2 cartridges. My Oki laser printers announced "toner empty" despite repeated attempts - no success! 2. cartridge similar. I strongly suspect that the cartridge was actually empty because no single Tonerstäubchen could be seen on the drum. The toner I had bought as a reserve. After returning the complete set of agreed only about two-thirds of the purchase price has been paid. Under no circumstances I provide a purchase recommendation!
