After the printer has the rebuild cartridges initially accepted without objection (with the missing ink level indicator I can live very well), he initially reported a problem with the black and a little later with the color cartridge. After several attempts to use the new cartridges, several times to restart the printer to take completely from the mains, and so we went again sometime for a few pages, and now is again totally Feierabend. Here HP seems to have not found an effective remedy for the Rebuild competition. This problem have so apparently many users. From a purchase is therefore not recommended. For a yield of less than 50 - 60 pages the price is then too high :-(
