MECHANICAL ALIGNMENTS
  • Disconnect the AC plug.
  • Remove the Top Case and Front Assembly.
  • Insert a cassette tape. Though the tape will not be automatically loaded, make sure that the cassette tape is all the way in at the inlet of the Cassette Holder. To confirm this, lightly push the cassette tape further in and see if the tape comes back out, by a spring motion, just as much as you have pushed in.
  • Turn the LDG Belt in the appropriate direction shown in Fig for a minute or two to complete this task.
To unload a cassette tape manually:
  • Disconnect the AC plug.
  • Remove the Top Case and Front Assembly.
  • Make sure that the Moving guide preparations are in the Eject Position.
  • Turn the LDG Belt in the appropriate direction shown in Fig until the Moving guide preparations come to the Eject Position. Stop turning when the preparations begin clicking or cannot be moved further. However, the tape will be left wound around the cylinder.
  • Turn the LDG Belt in the appropriate direction continuously, and the cassette tape will be ejected.  Allow a minute or two to complete this task.
Symptom of Misalignment:
  • If the tape path is unstable during reversing, the tape will be damaged.
  • Note: Do not use an Alignment Tape for this procedure. If the unit is not correctly aligned, the tape may be damaged.
  • Insert a black cassette tape into the tray and set the unit to REV. Then confirm if the tape has been curled up or bent at the Take-up Guide Post[4] or REV Post[5].
  • When the tape has been curled up or bent, turn the alignment screw to adjust the height of REV Post.
