Kusetshenziswa i-servo linear drive, ubude bokufakwayo kwefilimu ngesikrini esithintwayo. Ngommese ogoqayo, ifilimu ingasikwa ngokuzenzakalelayo. Ulayini we-sawtooth ungacindezelwa ngokuzenzakalelayo futhi unqamule umlomo wefilimu (njengebhokisi lethishu yobuso). Ukusebenzisa isilinda sokumunca ukubamba ifilimu esikiwe endaweni engenalutho, futhi indawo yefilimu ingalungiswa ngaphandle kokuma.
