Abstract

The printing quality delivered by a Drop-on-Demand (DoD) inkjet printhead is mainly limited due to residual oscillations in the ink channel. The maximal jetting frequency of a DoD inkjet printhead can be increased by quickly damping the residual oscillations and by bringing in this way the ink-channel to rest after jetting an ink drop. The inkjet channel model is generally subjected to parametric uncertainty. This paper proposes a robust optimization-based method to design the input actuation wave-form for the piezo actuator in order to improve the damping of the residual oscillations in the presence of parametric uncertainties in the ink-channel model. Experimental results are presented to show the efficacy of the proposed method.
