Abstract

PURPOSE:To eliminate the occurence of a striped pattern due to the change in droplets distance and raise the quality of printing by correcting dot displacement by a method in which the timing of charging on ink droplets injected from nozzles is exactly matched with the starting point of printing on a recording paper. CONSTITUTION:Charging pulse is divided into 1/3 by the DQ flip-flop circuit a dividing circuit 27 to obtain charging pulses a to c. On the other hand, encorder pulse is quantized by a charging pulse 3 times as much as the charging period to obtain a quantized charging pulse by which printing data is sampled at a gate circuit 40. The output of the gate circuit 40 is supplied to a shift resistor 41 for delaying. In a resistor 41, an output delayed by one bit is sent as charging data to a charging amplifier. When droplets distance is 3lambda at all times, the output of the circuit 44 and a normal charging voltage is obtained. However, when the droplets distance becomes 4lambda due to the synchronization with the concorder pulse, the output of the circuit 45 is obtained, the gain of the charging data amplifier is controlled, and corrected voltage is applied as a charging voltage.
