ABSTRACT:
A method of detecting malfunctioning ones of a plurality of nozzles of a printhead in an ink jet printer includes providing a sensor having at least two terminals defining at least one gap therebetween. An attempt is made to jet ink from a first of the nozzles into the at least one gap. A resistance between at least two of the terminals is measured to determine whether the ink has been jetted into the at least one gap. The attempting and measuring steps are repeated for each remaining nozzle.
