The magnet rack must be adjusted in two directions, horizontal and vertical.
The horizontal adjustment is done first. This adjustment positions the magnet rack correctly in rela
-
tion to the short pivot arms. If the printer prints too many or too few dots, the horizontal adjustment
could be the problem.
Then the vertical adjustment is done. This adjustment will affect the pressure the pivot arms put on
the printing pins. This directly affects the shape of the printed dots.
To be able to adjust the magnet rack correctly,
it is necessary to put the printer in “printing
position”.
This is done by rotating the main belt by hand
until the arrows at the ends of the shaft are
pointing exactly 180 degrees away from each
other.
It is possible to get the mechanism to balance
in this position, but you can also lock the shafts
with e.g. a self locking wrench (vice-grip pliers).
