I had to give two stars because of the fact that my printer become useless after using this product. Honestly, the seller tried to help at the beginning but after while the seller appears to be in silence mode . They knew that there is a defect in the cartridge especially the coloured one. I printed out pages after pages then send it to them. The ink flow was fixed and calibrated so many times. I tried all the solutions calibrating, ink flow, take the tube out and putting it back but result was really worse. After while the printer shows me an error light all the time. The printer is 3 months old and was working well before but after while that’s what had happened. I think there was a technical issue with the chips that cause the mother board to this situation. I can see that some people are doing well with it but my experience is not as good as them . That’s why I have to let you know about mine to be aware of all possibilities
