ABSTRACT:
An improved continuous stream ink jet printer is disclosed that conducts pagewidth printing via an array of fixed nozzles which direct droplets towards a moving recording medium. Each nozzle is assigned a segment of a printable line that extends across the entire width of the recording medium. The droplets from each nozzle are charged with printing information and fanned along its segment to specific pixels locations or to a gutter for recirculation. Distance sensing sensors are located below the droplet trajectories, parallel to the recording medium surface and perpendicular to the direction of movement of the recording medium. The distance sensing sensors periodically produce signals representative of the actual throw distance of the droplets and compare the signals indicative of the actual throw distance to a signal representative of the distance from the nozzles to a predetermined printing plane. The comparison signals are sent to the printer controller which adjusts the droplet trajectories in response thereto to correct the droplet placement errors that would be caused by variations in the throw distance produced, for example, by wrinkles in the recording medium or dimensional tolerance variations in the recording medium transport system where the printing occurs.
