Don't be afraid to contact HP Support for help. I just bought an HP2840 and after 2 months of very light printing (about 300 pages total, mostly B/W) the unit said "install magenta cartridge". All the other cartridges were 98% full but it wouldn't recognize the magenta cartridge as even being present. I couldn't print or copy B/W because of this fault. A simple phone call to HP Support got them to send me a new cartridge free of charge and it cleared up the problem. They even paid for return shipment of the defective cartridge.
