Abstract

An injection controlling device for an inkjet printer and a controlling method thereof includes determining whether an ink cartridge is installed in the inkjet printer, printing patterns in order by driving an ink injection heater with an array of predetermined pulses with widths that vary in sequential order in response to the ink cartridge being connected to the inkjet printer, detecting printing densities of the printed patterns; determining the pattern with an optimal density among the printing densities, and storing the width of the pulse corresponding to the pattern with the optimal density as an optimal pulse width.

Description

technical field [0001] The present invention relates to an inkjet printer, and in particular to an ejection control device for the inkjet printer and a control method capable of correctly adjusting the amount of inkjet. This application claims priority from Korean Patent Application No. 2002-67624 filed with the Korean Intellectual Property Office on November 2, 2002, the disclosure of which is incorporated herein by reference. Background technique [0002] A general inkjet printer drives an inkjet heater for ejecting ink in an ink cartridge, thereby printing on a printing medium. The inkjet printer includes a heater driving control unit for controlling the width or waveform of a driving pulse, thereby driving the inkjet heater according to the temperature of an ink cartridge head. [0003] figure 1 Drive pulses for a conventional inkjet heater are shown. P1 denotes a preheating pulse for preheating, P3 denotes a main pulse of the heater, and P2 denotes an interval betwee...
