6.2 CLEANING THE PRINTHEADS

You need to clean the printheads if your printout has missing dots,
banding problems, or alignment problems. You can perform printhead
cleaning or an initial ink charging (this also cleans the printheads) from the
control panel or the service program.
Note: See Chapter 5 for instructions for performing an initial ink charging
from the service program.
See Figure 6-1 for a quick overview of these options.
