Abstract
An ion writing system includes a writing unit and a calibration module. The writing unit includes an array of selectable electrode nozzles to direct ions onto passive e-paper to form a pattern of dots on the e-paper. The calibration module calibrates the writing unit for image optical intensity via information from a sensor.
