Printhead verification
You can verify that the printhead is the failing FRU by following this procedure:
1. Turn the printer off, and remove the power cord from the outlet. Remove all cords and cables from the
printer before beginning.
2. Locate the printer on a corner of a work area so the front and back can be accessed.
