ABSTRACT:
A method for determining a printhead gap between a printhead and a sheet of media in an ink jet apparatus that performs bi-directional alignment of the printhead includes determining a first amount of bi-directional misalignment of the printhead at a first unknown printhead gap; changing the printhead gap from the first unknown printhead gap to a second unknown printhead gap by a known printhead gap change amount; determining a second amount of bi-directional misalignment of the printhead at the second unknown printhead gap; and calculating at least one of the first unknown printhead gap and the second unknown printhead gap based on the first amount of bi-directional misalignment, the second amount of bi-directional misalignment, and the known printhead gap change amount.
