ABSTRACT:
A method enables an ink jet imaging device to normalize the driving signals for the ink jets within a print head of the device. The method includes generating an ink jet driving signal at an initial voltage and a particular resolution, coupling the ink jet driving signal to an ink jet for selective emission of ink from the ink jet onto an ink receiver in accordance with the driving signal, scanning the ink receiver and generating a line discontinuity signal indicative of a number of discontinuities detected in a line formed on the ink receiver by the ink ejected from the ink jet, and adjusting one of a voltage and a resolution for the ink jet driving signal in response to the line discontinuity signal received from the scanner.
