8 Faulty Printing Quality
!
WARNING
Settings for the printing quality may only be done by trained service
personnel.
Upon touching the print head a risk of burns may be present with a
defective heating element (see chapter 4.3).
The following points must be checked before searching for further caus-
es of faults:
•
Is the charge electrode slit perfectly clean?
•
Are the deflector plates and basis unit perfectly clean?
•
Is modulation/drop separation set correctly?
•
Is alignment of the ink jet in the charge electrode parallel/central?
•
Is system pressure set correctly (see chapter 6.2)?
•
Does the ink jet hit the gutter tube?
•
Correct ink density?
IMPORTANT
See also the enclosed CD for further information about printing quality
faults.
Correctly set printing quality:
Omitted or double drops. The horizontal and vertical drops do not form a
line.
System pressure too low. Modulation not adjusted correctly.
No straight lines to characters. The vertical drops overlap the horizontal
drops.
System pressure too high. Modulation not adjusted correctly.
