Abstract

PURPOSE:To impart stabilized electric charge to ink particles and increase phase margin to a great extent by sending a phase-searching signal during non-recording interval and ascertaining a phase suitable for particles, making phase-shift in every fixed cycle. CONSTITUTION:When printing signal S is inputted, data selector 23 is switched over to register 25 and phase signal D presenting the phase corresponding to register 25 is delivered from counter 22. Signal D is inputted in counter 32 and the output from counter 32 is inputted in counter 33. Counter 32 performs counting for the vertical dot, while counter 33 counts fo the horizontal, and the output from these counters 32 and 33 is inputted in letter-signal generating circuit 34 composed of ROM and others, from which dot signal E showing the presence of printing etc. is inputted to AND gate 35. Quantity of charge for ink particle 3 is given by counter 32, and both AND outputs are inputted in D-A converter 38, where ink particle 3 is electrified.
