4.3.2 Vacuum tests on the CPP head
NOTE
Using the type 2069 closed (red) nozzles
Make sure that you deactivate nozzle scanning when using the red nozzles.
In order to provide guidance when troubleshooting, a number of different modifications were made to
a CPP head and vacuum tests were then carried out with type 2057 open nozzles (calibration
nozzles) and type 2069 closed (red) nozzles, and the results were compared.
The modifications were always carried out on segment 1.
