Patent ID: 7556337

Claim:
An ink jet imaging device comprising: a motor configured to move an ink receiver; an imaging device controller configured to generate and to couple a speed signal to the motor to move the ink receiver at a speed corresponding to a particular resolution; a print head having a plurality of ink jets; a print head controller configured to generate a plurality of ink jet driving signals having an initial voltage and a particular resolution and to couple each ink jet driving signal to an ink jet to eject ink selectively from the ink jet in accordance with the driving signal received by the ink jet; a scanner having a signal summer and being configured to scan the ink receiver and to generate a line discontinuity signal indicative of a number of discontinuities detected in a line formed on the ink receiver by the ink ejected from at least one ink jet; and a driving signal adjuster configured to adjust one of a voltage and a resolution for an ink jet driving signal in response to the line discontinuity signal received from the scanner.
