I have only the color cartridges used in printers and meien first get an error message (Toner wrong / not kompatiebel etc.) After removing and re-installing the cartridges, were nevertheless accepted without bleating. But now spins the printer when it is printing with color (paper jam, printed part is at the top or bottom of the page, or even over it out!, Colors are not correct (wrong color components)). Bin'm very unhappy and buy original cartridges from Samsung nurnoch from now ...
