The first problem there when inserting the cartridge. The slack so that my printer she first did not recognize. Now that we have half an hour because rum pressed and tried, the printer detects Although the cartridges, but the color quality is very poor. Actually, black characters have a strong blue cast.
Added to this is that my printer does not accept both black cartridges at once. Then always get error messages. Now I have used one of the empty Canon cartridges. And since then you go, but the colors are not at all satisfactory.
I write otherwise actually no recessions, but this time I'm so upset that I already have to share my opinion shortly after receipt of the cartridges. I will prefer to invest in the future in any case my money in Canon cartridges !!!
