Cassette tape will not be ejected.
The problems covered here are all the result of the use of a bad tape (deformed or not properly tightened)
or of a malfunction of the cassette player itself. Malfunctions involving the tape becoming caught in themechanism and ruining the case are also possible, and attempting to force the tape out of the player
can cause damage to the mechanism. The player should be taken to a service dealer for repair.
