ABSTRACT:
An ink jet printing apparatus is disclosed in which, upon an accidental change in the direction of ink ejection to an uncontrollable range caused by ink set in a nozzle of its head or dust particles deposited thereon, ink ejection from the nozzle is interrupted immediately to avoid electric discharge and other possible accidents. An alarm representing such a failure may be produced simultaneously with the interruption of ink ejection.
