4. Check and adjust the ink stream position

•

Switch on the Ink flow sensor by pushing the button

<Ink flow sensor active>

(1) again.

•

Push the button

<Jet Adjust>

(2). The nozzle opens automatically to the

<Jet adjust position> (ca. 2100 -2300)

•

Check the ink jet: The jet must be positioned at the

inner edge

of the charging tunnel:

1 – Button <Ink Flow Sensor active>
2 – Button <Jet Adjust>

•

Now open the nozzle seal

completely

using the

<arrow key>

(1). Check the ink jet again:

Now the Ink stream must be in the

middle of the charging tunnel

and parallel to the

deflecting plates:

Important

It may happen that you have to re-adjust the drop production unit again after adjusting the ink

jet. Both procedures affect each other.
