ABSTRACT:
An apparatus for testing the driving of nozzles in an ink-jet printer having a plurality of nozzles for spreading ink and a nozzle driving unit for driving the nozzles by receiving a nozzle driving signal, includes: a nozzle drive detecting unit for detecting the variation of the voltage generated by the nozzle driving unit as the nozzles are driven, and for generating the predetermined detecting signal; a control unit for generating successively the nozzle driving signal fed to the nozzle driving unit, and for testing the driving state and finding defective nozzles when the detecting signal is inputted; and a result outputting unit for informing the user of the testing result performed in the control unit. It is possible for a user to take necessary actions according to the testing result, by informing the user of the number of defective nozzles which are found via the testing for the driving state of the nozzles instead of finding a defect manually.
