Some implementations may also apply the mask to the first set of drop ejection elements and the second set of drop ejection elements.

Abstract: An ion writing unit including an ion generator and an array of electrode nozzles aligned to receive and guide generated ions. The ion writing unit convertibly operates between at least a first mode and a second mode. In the first mode, ions flow from the ion generator through selected nozzles at a first flow rate to cause image formation on an electrically biased passive e-paper spaced apart from the electrode holes. In the second mode, ions flow from the ion generator through at least some electrode nozzles at a second flow rate that does not cause image formation on the electrically biased passive e-paper.
