25. Uneven Revolution. Tape Speed Is Fast or Slow

DIAGNOSIS

STEP 1. Does the player work normally if the tape is changed?

NOTE: Check that the tape label is not loose, that the tape case is not deformed and that the tape is tightly wound. Also, tape with a length of C-120 or greater can often get caught in the mechanism and should not be used.

If yes, the tape used is defective. The cassette tape speed should be stable.
If no, go to Step 2.

STEP 2. Are there any foreign objects inside the cassette player?

NOTE: Attempting to eliminate a foreign object (e.g., a coin or clip, etc.) out of the cassette player may damage the mechanism. The player should be taken to a service dealer for repair.

If yes, the cassette tape speed should be stable. If no, go to Step 3.




STEP 3. Is the head or capstan roller dirty?
If yes, clean the head or capstan roller. The cassette tape speed should be stable.
If no, repair or replace the tape player. The cassette tape speed should be stable.
