Title:
APPARATUS AND METHOD FOR DRIVING INK JET RECORDING HEAD
Document Type and Number:
Japanese Patent JP3225987
Kind Code:
B2
Abstract:
PURPOSE: To enhance the response speed of an ink jet recording head and to also prevent the clogging of a nozzle.
CONSTITUTION: In an ink jet recording head having a pressure generating chamber 1, the nozzle orifice 2 communicating with the pressure generating chamber 1 and emitting ink, a piezoelectric vibrator 7 generating pressure in the pressure generating chamber 1 and a voltage applying means applying voltage to the pressure vibrator 7, the pressure generating chamber 1 is expanded at predetermined speed in matching relation to a point of time when a meniscus generated after the flight of an ink droplet is most drawn in. This operation is performed regardless of the presence of recording data.
