ABSTRACT:
Fluid jet printing apparatus having a fluid jet printhead and a pair of substrate positioning rolls for moving the substrate between a position below the printhead for printing on the substrate and a position removed from the printhead enabling access to the printhead. Two or more printing stations, each having a fluid jet printhead and substrate positioning rolls, are serially aligned in the direction of movement of the substrate to print different fluids on the substrate. Idler rolls are arranged to effect printing on opposite sides of the substrate at the respective printing stations. The direction of travel of the substrate past the printhead may be in a direction to first pass the catcher and then the droplet streams thereby minimizing or eliminating the tendency of particles to enter the region of the electrodes.
