Press the button <Jet Adjust> (12). The gutter motor of the print head is now
moving automatically to the required setting position (approx. 4200).
Note: Smaller deviations from the given setting position are in the tolerance
range of the system!
The ink jet has to be now adjusted with the two setting screws 13) according to
the following picture (jet adjustment (step2)) to the gutter tube (14).
By turning the upper setting screw (13.1) clockwise the ink jet moves to the
direction of the gutter tube top edge. Counter-clockwise the jet moves to the
direction of the gutter tube bottom edge.
Note: Line of sight from the nozzle to the gutter tube.
By turning the lateral setting screw (13.2) clockwise the ink jet moves to the
direction of the left gutter tube angle. Counter-clockwise the jet moves to the
direction of the right gutter tube angle.
Note: Line of sight from the nozzle to the gutter tube.
After carried out adjustment of the jet position in the gutter tube the complete
jet generation unit has to be adjusted in the charging tunnel (15) and in the
deflection plates in this way that the ink jet is parallel and flush with the left
angle of the charging tunnel.
Note: Line of sight from the nozzle to the gutter tube.
Setting sequence:
1. Open the 5 locking screws on the fixing plate (17) as far as the unit can be
moved by hand.
2. Move the unit carefully until the ink jet corresponds with the shown setting
position.
3. Fix the settings by tighten the locking screws (17).
4. Check the setting positions after fixing again and if necessary correct the
position again.
Now the nozzle seal has to be opened completely to souse the ink jet completely
into the charging tunnel (15). For this press on the arrow button <Open
nozzle> (18) and keep it pressed until the gutter motor has reached it's end
position.
Release R1.03e
Data/Programming
Attention! The ink jet should be absolutely parallel to the
deflection plates.
For the optical evaluation of the jet position it is important that the
angle of view is exactly adjusted vertically from above via the
charging tunnel and ink jet to exclude parallax errors as far as
possible.
