Abstract (en)
Deflection electrode arrangement (10) for ink jet printer wherein charged ink droplets are deflected by charge deflection electrodes (21, 22) to effect printing, including a tunnel (20) for passage therethrough of air and the stream of ink. Within the tunnel (20) are first (21) and second (22) longitudinally extending deflection electrodes in spaced apart confronting relation for effecting deflection of the charged drops in the ink stream passing therebetween. Electrically conductive continuations (26, 27) of at least one (22) of the deflection electrodes extend towards the other electrode (21) and along the interior of the tunnel (20) so that during start up and shut down of the ink stream, misdirection of drops from the intended stream direction which would normally tend to impact the sidewall of the tunnel (20) will strike the electrically conductive continuations (26, 27) of the deflection electrode (22) thereby accommodating ink drop contamination of the tunnel interior.
