This occurs after the toner particles pass through a line of electrodes in the form of tiny wires, or nibs.
Dry Toner models use a process similar to xerography in photocopiers.
Unlike a laser printer or photocopier, there is no transfer drum used in most electrostatic plotters; the imaging paper is directly exposed to the charging electrode array.
Electrostatic plotters can print in black and white or in color.
[2] Modern electrostatic color plotters are found in the short run graphics industry, printing on a variety of paper or plastic film surfaces.
