Abstract:
1. A method for normalizing an ink jet that emits ink onto an imaging drum in an imaging device comprising: 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; counting voids in the line discontinuity signal with a signal summer in a scanner; comparing the counted number of voids to a continuous line threshold to detect whether the line formed on the ink receiver is substantially continuous; adjusting one of a voltage and a resolution for the ink jet driving signal in response to the comparison of the counted number of voids to the continuous line threshold indicating the line formed on the ink receiver is substantially continuous.
