INK JET RECORDER AND PRINTER DRIVER

摘要

PROBLEM TO BE SOLVED: To solve a problem that inner pressure variation can not be prevented effectively in a nonejection channel. SOLUTION: A first driving waveform for ejecting an ink drop is applied to a channel for ejecting an ink drop and a second driving waveform for displacing a diaphragm without ejecting an ink drop in phase with the first driving waveform is applied to a channel not ejecting an ink drop.
