ABSTRACT:
In the case where the synchronism between the timing of generation of ink droplets and the phase of the information signal in an ink jet printer and deflection sensitivity of the droplet are checked by charging certain ink droplets with the phase detection signal voltage or the droplet deflection sensitivity detecting signal voltage, the certain ink droplets appearing at intervals in place of ink droplets for information recording, each of the ink droplets for recording information just following the certain ink droplet experiences distortion in electrification. This invention provides a circuit for compensating the voltage for charging those ink droplets for information recording which just follow the ink droplets for usage excepting information recording, e.g. droplet deflection sensitivity detection or phase detection etc.
