Have only one cartridge in the printer tried, which was also recognized without difficulty. The few sites that I've printed nothing could determine negative. The only thing I was not accustomed to the relatively small reservoir, which seems however to have the original size. - The otherwise ordered by a competitor cartridges have an appreciably larger tank, I always get one or two free offerings on your order (which you do not always really needs), so I think to be a total of not fared much cheaper. Overall, the cartridges are however especially when compared to the original seeeehhrr low.
