Cartridges are already equipped with a chip of the level display support.
That change, quite simply, the old out and the new pure, that's :-) -> no annoying chip remodeling longer necessary
From the print quality, I am amazed at the photo printing and the normal pressure no deterioration to the original ink.
Whether the printed photos retain their color or fade, I see then at least one year.
So I recommend everyone these cartridges whether for photo printing or text - image printing.
Definitely these cartridges are much cheaper than the originals, and that's the most important!
