Paper Abstract

Based upon the purpose of prolonging the lifetime of an ink- jet head, we have attempted to apply double pulse to a heater during a drop ejection cycle. There are five parameters (pulse widths and voltages and the time delay) to define the double pulse. Taguchi's method is used to investigate the effects of these parameters. The experimental results show that under the optimized condition with (18 V, 2 microseconds), (14 V, 4 microseconds) and delay time 12 microseconds double pulse can prolong the life of ink jet heads up to an averaged drop counts of 4.8 X 108 as compared with that of 3.0 X 108 using single pulse. Also, improper parameters can dramatically shorten the life of an ink-jet head, or disturb the drop formation.
