ABSTRACT:
A control system for an inkjet printer to deliver a drive voltage to a piezoelectric element to discharge an ink drop and to reduce the effects of post-discharge vibrations propagated through an ink reservoir within a printing head of the inkjet printer. The control system can reduce the effects of post-discharge vibrations by delivering a secondary pulse to the piezoelectric element following delivery of the drive voltage and/or tailoring the leading and trailing edges of the driving voltage.
