Does anybody have the answer to "Problem with Printhead" on ho 6830.. Change the head and Main board and still same message. Does this even without cartridges in so can't be ink. doea print out all reports in white and cleans printhead if you in the sevvice menu and select AUDIT !! I this to be honest it's the firmware but can't find any original on the net as it seems HP have deleted the links..I am experienced electronics engineer so maybe someone has the circuit or what brings the message up in normal mode. P.S. the New head was an original HP head and could,'t believe it when I intalled the head and same messae..Printer hardle done any work and still has the setup cartridges in. Roger
