							9.Close and lock the printer window.
10.The front-panel display confirms that all of the printheads are correctly inserted. The printer starts
checking and preparing the printheads. The default routine process, when all printheads are
changed, takes up to 18 minutes. If the printer identifies a problem when preparing the printheads,
the process takes longer, up to 30 minutes. For a single printhead insertion, the time varies between
10 and 20 minutes. After all printheads are checked and prepared, the printhead realignment
procedure runs automatically if substrate is loaded. See the Maintenance and troubleshooting
guide.
