Title:

INK DROPLET JETTING DEVICE

Document Type and Number:

Japanese Patent JP2007196554

Kind Code:

A

Abstract:

To attain a higher recording speed by reducing the overall pulse width to enhance a driving frequency, in an ink droplet jetting device jetting a plurality of ink droplets per dot.

A driving pulse signal for forming one dot includes a plurality of main pulses Pm1, Pm2, Pm3 ranging at an interval for performing jetting operation and a stabilizing pulse Ps1 which is inserted among the main pulses Pm1, Pm2, Pm3 and suppresses the residual oscillation of the ink in a pressure chamber generated by the main pulses positioned before the stabilizing pulse, in which the last main pulse Pm3 in the main pulses for forming one dot performs the jetting operation and also suppresses the residual oscillation of the ink in the pressure chamber generated by the jetting of the ink.
