Simulation and Analysis of LHD Ship Airwake by Navier - Stokes Method

An ink jet printer is disclosed employing a row of multiple ink jet nozzles aimed at a moving target or copy sheet. Each nozzle has a separate charging electrode associated with it but all the nozzles share a pair of common deflection plates that divert charged droplets over a shared gutter toward the target. Uncharged droplets go into the gutter. An electrostatic lens is shared by all the nozzles being positioned in the path of the charged droplets deflected toward the target. The lens aligns or focuses charged droplets from all the nozzles to a focus line on the target despite misalignment of nozzles relative to a print line on the target.
