Product: HP Officejet Pro 8100 ePrinter - N811a/N811d

Since I had to replace the last 951 magenta cartridge because it was empty, my printer keeps telling me that any new cartridge I insert is faulty and therefore it can't print. I tried with 3 different cartridges, 2 brand new genuine HP and one that was previously used in this printer that still has some ink left in it. I tried cleaning the contacts on the cartridges and on the printhead but nothing works.
