Cleaning
The Jet Status Lines test provides a quick method of determining
the effectiveness of (or the need for) cleaning. This test prints a
pattern of lines, each segment of which corresponds a single jet.
If there are any missing segments in the lines, then a cleaning is
recommended. If, however, the lines appear solid and consistent,
then cleaning is most likely not required at this time. See “Jet
Status Lines” on page 4-7 for instructions.
The AutoSet calibration can also indicate that cleaning is
needed. When AutoSet maps out a significant number of jets
due to D (missing), or X and Y (alignment) errors, it is probably
due to clogged and deflected jets. In this case, cleaning is recom-
mended.
