Hint:
Due to the constructional positioning of the adjusment screws, there will be always
a movement like a skew during the adjusment on any screw. Due to this existing skew,
usually both adjusting screws must be adjusted for the correct attitude.
5. After adjustment of the entire drop production unit into the charging tunnel
and deflecting plates, it has to be adjusted in such a way, that the ink stream knew parallel
and concisely with the internal left of the charging tunnel.
(Viewing direction: From nozzle toward gutter tube)
The ink stream should run absolutely parallel to the deflecting plate.
Required tools:
6-fold magnifying glas
Allen key (SW 1,5) or Torx (T6)
During the optical evaluation of the radiation situation it is important that
the point of view is directed exactly perpendicularly from above via the charging tunnel and
ink stream, in order to exclude a parallax error to a large extent.
Attention: It is not allowed to use a ball head allen key.
The screw heads could be damaged!
