The pulses may be binary or analogue to scan the droplet train. In the case of analogue pulses, a combination of digital pulses may be applied to a charging ring (Fig. 5A, not shown) or each charging segment may comprise segments forming a ring, the segments being graded in size (Fig. 5B, not shown).</p> |
