Device and method for driving jetting head |
摘要 |
There is disclosed a head driving device which drives a plurality of pressure generating elements for generating pressure fluctuation in a jetted object contained in each of associated pressure chambers formed in a jetting head of a jetting apparatus to eject the jetted object from each of nozzles communicated with the associated pressure chambers. In the device, a head driver generates a drive signal which is selectively applied to at least one of the pressure generating elements to be driven. A bias potential provider selectively applies a bias potential to at least one of the pressure generating elements not to be driven.
