The drawing on this page is to help to understand the basic principle of how the dots are printed. Please
also see the drawings on the next page.
The parts in the upper left of this drawing is one of the magnet racks. The parts in the lower rigth,
are the beam and paper shoes. The magnet racks do not move, but the beams and the papershoes are
moving up and down for every revolution of the eccentric shafts.
Inside each magnet rack there are 42 electrical magnets. The magnets are controlling the long
pivotarms.
When a dot is going to be printed, the magnet is engaged, and the long pivot arm will be drawn
against the magnet poles.
At the same time, the beam and the papershoe will start to move downwards, and the short pivot arm
will catch the hook of the long pivot arm. The beam will continue to travel downwards, and will force
the printing pin into the paper.
