Installation worked immediately, but as expected, the printer reports naturally "missing cartridge". I'm used to and do not bother me further. But since I do not have as much printed, the amount of ink has dried very quickly. One probably. was also not so much in it ... Could you in any case after a few days when pulling on an absorbent paper elicit no matter how pale streaks more. Have my experience with compatible cartridges, which is why I would not buy this. Will once again buy the original cartridges and refill later. This has worked well for 1 year. One must only do not let the cartridge run dry, but fill sooner, then you also get no error messages.
