I bought an HP MFP C1312NFI OCCAZ with consumables to zero. For back in the saddle, I bought this kit. I'm updating the latest firmware from June 2014, and I installed the cartridges. Contrary to what I read in other reviews, the toner (yellow) was not recognized as original HP. After calibration is required by the machine, first impression of a traditional 10x15 photo on 80g paper. Stunning result. Excellent holding of the powder to the substrate contrary to what I read in another review. In short, satisfied. See it on the length, but at first glance, everything is going. I have not put 4 stars for the fact that it is not recognized as an original, but functional view RAS.
