Hello, I agree with the above post, usually you see those errors in regards to the ink system, if you purchased one of the first models of this series it is a manufactures defect. If the machine is still under warranty I would get with HP and have them replace the machine, if you are unable to get the machine to come to ready after the troubleshooting that the above post suggested. Or if you want to be brave you can order and replace the printbar, but I highly recommend having HP replace the machine, as replacing the printbar is not easily replaceable.
Hope this helps.....
