Abstract

PURPOSE: To obtain the print of uniform density and to reduce noise sound, by obtaining the sane print force as the continuous driving even with a single driving and by correcting the fifference between the both print forces, thru the provision of a resistor in parallel with the transistor turning on and off the current flowing into the magnet.
