Atechnician has been asked to test an inkjet printer purchased 6 months ago that is being pulled from stock and put into use for the first time. the documentation indicates that the unit was successfully tested after it was received. after attempting to connect and install the driver, he finds that neither the self-test page nor the windows test page produces print on the paper. he pulls the inkjet cartridge out and shakes it, determining that it has ink in it. what should he do next?
