    process, click  Cancel.
    If cleaning the head once does not resolve the print head problem, clean it once more.

    not resolve the print head problem.

    Cleaning the print head frequently will rapidly deplete your printer's ink supply. Consequently, perform
    cleaning only when necessary.
    Note
