Ink jet printing apparatus |
摘要 |
An ink jet printing apparatus includes a controllable gain charge amplifier circuit adapted to supply a charging electrode with a charge voltage. A reference charge voltage is coupled to the charging electrode to detect an actual position to which charged ink droplets are deflected. The gain of the amplifier circuit is automatically determined so that the actual deflection position coincides with a predetermined reference position. Moreover, the determined gain of the amplifier is automatically adjusted in accordance with charges on preceding droplets to compensate for any distortion of a charge to be deposited on an immediately following droplet attributed to the charges on the preceding droplets.
