Figure 70 is a schematic diagram of a printer nozzle depositing ink onto paper. The nozzle is situated above the paper and contains ink. There is a small rectangle drawn on the side of the nozzle labelled 'Heat or piezo element'. An S-shaped line connects this rectangle to a larger rectangle labelled 'Image data'. Ink droplets are shown falling from the nozzle, landing on the paper to create a line of droplets along the top surface of the paper. The droplets are not equidistant.
