When all of the printheads have been inserted correctly and the printer has accepted them, the printer
beeps.

9. Close 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.
