Abstract

An inkjet printer head driving apparatus and a control method thereof include a switching unit turning on and off each of heating elements to heat and eject ink through nozzles, a level shift unit having a level converter converting to a predetermined potential level a potential level of a signal inputted to drive the switching unit, a transient time extending part provided with at least one time extending element to extend a transient time during which a potential level of the signal inputted from the level converter to the switching unit is converted from a first signal level to a second signal level and vice versa, and a control unit outputting to the level shift unit the delayed signal as a nozzle selection signal to select the nozzles corresponding to a to-be-recorded image.

Description

[0001] This application claims priority from Korean Patent Application No. 2002-77320 filed in the Korean Intellectual Property Office on December 6, 2002, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to an inkjet printer head driving device and its control method, in particular to an inkjet printer head driving device and its control method for minimizing high-frequency noise components, when driving a heating element to pass through the printer head The high-frequency noise component may occur when ejecting ink from the nozzles formed on it. Background technique [0003] Generally, a printer prints images or information processed by an external device such as a computer on a recording medium such as paper. The printers are mainly classified into one of a wire dot type, a thermal transfer type, and an inkjet type. [0004] The inkjet printer head has a plurality of nozzles for ejecting ink to form an im...
