This topic describes the cleaning cycles used to clean jets of bubbles or foreign
matter that causes a jet to malfunction. Three basic actions take place during a
cleaning cycle:
purging
wiping
flushing
These actions are used in different combinations for three different types of
cleaning cycles:
quick wipe
short cleaning
long cleaning
The long cleaning is described here. The short cleaning and the quick wipe are
basically subsets of the long cleaning cycle.
