Hi, have a 12 XL replacement was chip cartridge package compatible erwoben to Canon PGI-550BK XL Black, CLI-551BK XL Photo Black, CLI-551C XL Cyan, CLI-551m XL Magenta, CLI-551Y XL, after I translated the first cartridge magenta for the time being all right. After a relatively short time I was shown that exactly this cartridge is almost empty again. Other cartridges not yet changed. Have therefore the magenta cartridge removed from the printer to look up how much ink is remaining after a little residual ink was available I have been translated back into the printer. Behold, the printer will not recognize this cartridge, the empty original cartridge is detected. Résumé, cartridge is no longer usable. I'm curious how behave the remaining 11 cartridges.
