Method of driving piezoelectric type ink jet head |
摘要 |
Disclosed is a method of driving a piezo-electric type ink jet head for jetting inks out of a nozzle by making use of a distortion of a piezo-electric element. The driving method includes a first step of driving the piezo-electric element so that a meniscus of inks is receded from an initial position of the nozzle to a first position within the nozzle, a second step of driving the piezo-electric element so that the meniscus quickly advances from the first position to a second position within the nozzle, and a third step of driving the piezo-electric element so that the meniscus slowly advances from the second position to the initial position. A particle quantity of ink particles is changed by changing a movement quantity from the fist position to the second position in the second step. <IMAGE> |
