PCA) and the backup EEROM (located in the Ink Supply Station)
contain false values or because both of them have failed.

to cap the Printheads. Once unlocked, the Carriage Assembly can
then be moved freely along the Printer by hand.

after they have been replaced (or if a situation arises where you need
